MPXV7007GP - ±7kPa Compound Pressure Sensor, 5V SOP-8 | STMicroelectronics
The STMicroelectronics MPXV7007GP is a monolithic silicon piezoresistive pressure sensor that measures compound pressures from -7 kPa to +7 kPa (-1.02 to +1.02 PSI) and converts them to a ratiometric analog output of 0.5 V to 4.5 V at 5 V supply. It is housed in an 8-pin Small Outline Package (SOP-8) with a top-side port and gull-wing leads for surface mounting. What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a MEMS device that uses diffused strain gauges on a silicon diaphragm; when pressure is applied, the diaphragm flexes and changes the resistance of the gauges, producing a differential voltage proportional to applied pressure. Piezoresistive sensors sit within the hierarchy of pressure sensors -> MEMS sensors -> sensors -> electronic components, and are widely chosen for low-pressure medical, HVAC, and instrumentation uses because of their high sensitivity, low cost, and integrated signal conditioning. Key features of the MPXV7007GP include on-chip signal conditioning, factory calibration, temperature compensation from 0 °C to +85 °C, and a typical full-scale span of 4 V at 5 V supply. The device operates from a single 5 V supply (4.5 V to 5.5 V), draws 10 mA typical supply current, and includes EMC and reverse-polarity protection. The compound range allows both vacuum and positive pressure measurement with a single device, simplifying manifold and bidirectional flow designs. Technically, the MPXV7007GP uses bipolar processing with thin-film metallization combined with advanced micromachining to deliver an accurate, high-level analog output that interfaces directly to microcontroller A/D inputs without external compensation. The 0.5 V to 4.5 V output spans nearly the full ADC range of a 5 V MCU, maximizing resolution. Typical applications include HVAC variable-air-volume controls, medical respirators and ventilators, process controls, level sensing, and portable/wearable airflow monitoring. The compound range makes it ideal for measuring both positive and negative pressures in respiratory circuits and duct work. When designing with this part, place a 0.33 µF decoupling capacitor close to the supply pin and a small RC filter on the output if the ADC input is in a noisy environment. Avoid kinking or blocking the side port, and respect the maximum tube diameter of 0.13 in (3.17 mm) to prevent leaks.

MPXV7025DP - 5V ±25kPa Differential Pressure Sensor | NXP/ST
The NXP Semiconductors (originally Freescale, now also distributed by STMicroelectronics) MPXV7025DP is a state-of-the-art monolithic silicon piezoresistive pressure sensor rated for ±25 kPa (±3.63 PSI) differential measurement in a dual-port SOP 8 (8-BSOP, 12.06 mm width) package. It operates from a single 5 V supply and provides a temperature-compensated, calibrated analog output of 0.2 V to 4.7 V over the rated pressure range, ready to feed directly into a microcontroller ADC input. What is a differential pressure sensor? A differential pressure sensor measures the pressure difference between two ports (a high-side inlet and a low-side reference) and outputs a voltage proportional to that delta. It belongs to the pressure sensor family under MEMS (micro-electro-mechanical systems) and silicon piezoresistive transducers. Differential sensors are widely used for flow sensing (via orifice or pitot tube), filter blockage detection, altitude/altitude-derivative sensing, and HVAC duct monitoring, where only the difference between two points — not an absolute reference — matters. Key features include on-chip signal conditioning (no external calibration required), temperature compensation across 0 °C to +85 °C, ±5 % linearity over the primary pressure range, and a sensitivity of approximately 90 mV/kPa at 5 V excitation. The patented single-element transducer combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing — an architecture inherited from earlier Motorola/Freescale MPX series devices. Technically, the device uses a Wheatstone-bridge of piezoresistors diffused into a silicon diaphragm. When pressure is applied across the dual ports, the diaphragm flexes, unbalancing the bridge and producing a differential voltage that is then amplified and offset on-chip to the 0.2 V – 4.7 V output swing. The result is a ratiometric analog output that scales proportionally with supply voltage, simplifying ADC interface design with 3.3 V or 5 V microcontrollers. Typical applications include HVAC duct airflow monitoring, medical respirators and CPAP machines, industrial process control, water-level detection in sealed tanks, and altitude/altitude-derivative measurement in drones and wearables. Designers choose this part when they need a calibrated, drop-in analog solution rather than a digital I²C/SPI sensor. When designing in, place 100 nF decoupling close to the supply pin and use a stable, low-noise 5 V source — the output is ratiometric, so any supply ripple couples directly into the reading. Add a small RC low-pass filter on the output if driving long cables to suppress EMI pickup.

MPXV7025DPT1 - ±25 kPa Differential Pressure Sensor | NXP
The NXP MPXV7025DPT1 is a piezoresistive differential pressure sensor rated for ±3.63 PSI (±25 kPa) full-scale range, delivering a calibrated analog output of 0.2 V to 4.7 V in an 8-BSOP surface-mount package with dual ports on the same side. The integrated transducer combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing to provide an accurate, temperature-compensated signal that interfaces directly to a microcontroller or microprocessor A/D input. A pressure sensor is a transducer that converts an applied physical pressure into a proportional electrical signal. Within the broader sensor hierarchy, the MPXV7025DPT1 belongs to the piezoresistive family, where strain gauges embedded in a silicon diaphragm change resistance when mechanical stress is applied. It sits under MEMS (micro-electromechanical systems) sensors, which themselves are a sub-class of semiconductor sensors used in industrial, medical, and consumer monitoring. Differential variants, like this one, measure the pressure difference between two ports rather than absolute or gauge pressure, making them ideal for flow measurement and filter monitoring. Key features of the MPXV7025DPT1 include a 5.0 V typical supply, an on-chip signal conditioner and temperature compensation circuit, a ratiometric analog output, and a 0.475-inch (12.06 mm) wide 8-BSOP housing with two 0.13-inch (3.302 mm) male tube ports on the same side. The output span of 4.5 V across the ±25 kPa range gives approximately 90 mV per kPa sensitivity, simplifying firmware calibration on the host MCU. Technically, the device leverages Freescale's (now NXP) patented single-element transducer design, which provides a single piezoresistive die that responds symmetrically to positive and negative differential pressure. The integrated ASIC normalizes the offset, span, and temperature drift, eliminating the need for external compensation components. This monolithic integration delivers a typical total error of under 5% across 0 °C to 85 °C, suitable for closed-loop control without factory recalibration. Typical applications include HVAC variable-air-volume (VAV) controllers, patient monitoring airflow, process control manifolds, and water-level / filter-pressure detection. The differential topology allows bidirectional flow sensing when used with pitot tubes or orifice plates. The same-side dual port arrangement simplifies plumbing layout for inline measurement. When designing with the MPXV7025DPT1, take care to vent the unused port appropriately for gauge-style applications, and keep fluid-path tubing short and stiff to avoid mechanical resonance. Add a small RC low-pass filter on the analog output if the host ADC samples at a low rate to suppress conducted noise from pumps or motors. This page synthesizes distributor pricing, cross-validated drop-in alternatives, application-specific recommendations, and practical design notes - information beyond the raw manufacturer datasheet to accelerate part selection and PCB implementation.
MPXV7025GC6T1 - ±25 kPa Pressure Sensor, 5V, Top Port | NXP
The NXP MPXV7025GC6T1 is an integrated silicon pressure sensor with on-chip signal conditioning, temperature compensation, and calibration, housed in an 8-SMD gull-wing package with a top axial pressure port. The device measures gauge pressure from 0 to +25 kPa (0 to +3.63 PSI, compound range down to -25 kPa) and provides a ratiometric analog output of 0.2 V to 4.7 V from a 4.75 V to 5.25 V supply. The MPXV7025GC6T1 targets board-mount applications where a small, calibrated, factory-trimmed pressure-to-voltage transducer is required. A board-mount pressure sensor, also called a piezoresistive transducer or pressure sensor IC, is a semiconductor device that converts applied pressure into a proportional electrical signal. Within the broader hierarchy, this places it as a pressure sensor -> sensor -> transducer -> signal conditioning device. Piezoresistive sensors use a Wheatstone bridge of strain-sensitive silicon resistors etched into a diaphragm; when pressure deflects the diaphragm the bridge produces a differential voltage that is then amplified and offset on-chip. The integrated signal path of the MPXV7025GC6T1 eliminates external compensation circuitry, simplifying design-in. Key features include factory calibration across 0 to 85 °C, a low supply current of approximately 7 mA typical, an operating temperature range of -40 °C to +125 °C, and a top-side axial port that accepts 3.18 mm tubing for direct connection to the measured gas. The output is ratiometric with VDD, which means the full-scale span scales with supply voltage and allows simple ADC interfacing using the supply as the reference. The 8-SMD, gull-wing package simplifies SMT assembly and provides mechanical robustness for industrial environments. The MPXV7025 series piezoresistive transducer is built on a monolithic silicon process that integrates the sensing diaphragm, the Wheatstone bridge, and the signal-conditioning ASIC on a single die. The on-chip ASIC provides offset trimming, span calibration, and temperature compensation, so designers do not need to perform multi-point calibration in firmware. This architecture yields a typical accuracy within a few percent of full-scale span across the calibrated temperature range, which is sufficient for HVAC, medical respiratory, and appliance applications. Typical applications are HVAC damper control and airflow monitoring, medical respiratory equipment such as ventilators and CPAP machines, appliance pressure sensing including washing-machine water level and dishwasher flow, altimeters and barometric aids, and industrial pneumatic control. The 0.2 V to 4.7 V output swings nearly full-scale between the rails and is well matched to 5 V ADCs and microcontrollers. When designing with this device, ensure the supply is well regulated because the output is ratiometric: noise or drift on VDD appears directly on VOUT. Place a 100 nF decoupling capacitor close to the VDD pin and a small capacitor on the output if the load is highly capacitive. The axial port accepts 3.18 mm tubing; use flexible silicone or polyurethane tubing with a press fit, and avoid kinking the line near the port.

MPXV7025GC6U - ±25kPa Compound Pressure Sensor, 5V | ST
The STMicroelectronics (formerly NXP/Freescale) MPXV7025GC6U is a monolithic silicon piezoresistive pressure transducer in an 8-SMD gull-wing SOP package with a top axial port, rated for ±25 kPa (±3.63 PSI) compound pressure measurement with a 0.2 V to 4.7 V ratiometric analog output. A pressure sensor is a transducer that converts an applied pneumatic or hydraulic pressure into a proportional electrical signal. Within the broader sensor taxonomy, the MPXV7025GC6U is a board-mount MEMS pressure sensor -> piezoresistive transducer -> signal-conditioned analog sensor -> MEMS device -> semiconductor. The 'compound' rating means the device measures both positive gauge pressure (up to +25 kPa above atmospheric) and negative vacuum pressure (down to -25 kPa below atmospheric) on a single output span, which is essential for applications such as medical vacuum systems, HVAC, and engine manifold monitoring where the pressure can swing across atmospheric reference. Key features include on-chip signal conditioning, temperature compensation between 0 °C and 85 °C, and calibration that eliminates the need for external trim components. The 5 V typical supply with ratiometric output (VOUT/VCC scaling) provides 90 mV/kPa nominal sensitivity over the full ±25 kPa span, plus ±5 % accuracy after calibration. The patented single-element transducer combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing to deliver stable, repeatable performance with long-term drift typically below 1 % per year. Typical applications include HVAC variable-air-volume (VAV) controllers, medical respiratory and vacuum equipment, industrial process control, altimeters and variometers, and engine manifold absolute/relative pressure sensing. The 8-SMD top-port package simplifies pneumatic connection via 3.18 mm (0.13 in) tubing while keeping the PCB-side reflow-compatible. When designing with this device, ensure that the analog supply (VCC) is well decoupled with a 100 nF ceramic capacitor placed within 5 mm of the supply pin, and avoid sharp tubing bends at the axial port to prevent stress on the package. The output is ratiometric to VCC, so any noise on the 5 V supply will translate directly into output noise — use a low-noise LDO for best results.

MPXV7025GP - ±25kPa Compound Pressure Sensor, 8-SMD | NXP Semiconductors
The NXP Semiconductors MPXV7025GP is an integrated silicon piezoresistive pressure transducer with on-chip signal conditioning, temperature compensation, and calibration, measuring ±3.63 PSI (±25 kPa) compound pressure. Housed in an 8-SMD gull-wing package with a side-mounted 0.13" (3.18 mm) tube port, it delivers an analog output of 0.2 V to 4.7 V proportional to applied pressure for direct microcontroller ADC interfacing. A pressure sensor is a transducer that converts an applied pressure into a proportional electrical signal, typically voltage. The MPXV7025GP belongs to the integrated silicon pressure sensor family (piezoresistive transducer -> MEMS pressure sensor -> pressure sensor -> sensor IC), combining a micromachined silicon diaphragm with on-board ASIC conditioning. This integration eliminates the need for external amplification or temperature compensation circuitry, simplifying design-in for engineers. Key features include a compound pressure range allowing both positive and vacuum measurement, a ratiometric analog output suitable for 5V supply systems, and factory calibration that removes user-side trimming. The device operates over a wide supply voltage with low power consumption and provides temperature-compensated output across its specified operating range. Its integrated signal chain produces a clean analog voltage that maps linearly to applied pressure, reducing software overhead. The MPXV7025GP is built using NXP's proprietary MEMS piezoresistive technology combined with a bipolar op-amp signal-conditioning ASIC. The Wheatstone bridge formed by implanted resistors on the silicon diaphragm produces a differential millivolt signal that is amplified, offset-corrected, and temperature-compensated to deliver a ground-referenced 0.2 V to 4.7 V swing. This single-chip integration dramatically improves noise immunity compared to discrete transducer designs. Typical applications include HVAC air-flow monitoring, respiratory equipment, barometric compensation for altimeters, process control systems, and medical vacuum/pressure monitoring. The compound range enables measurement in systems that see both pressure and vacuum. When designing with this part, decouple the VCC pin with a 100 nF ceramic capacitor placed close to the sensor leads. The output is ratiometric to VCC, so for highest accuracy, ADC read the regulator should share the same supply rail as the sensor or use a precision reference.

PX309 - Stainless Steel Pressure Transducer 5000 psi | Omega Engineering
The Omega Engineering PX309-5KGI is a stainless-steel industrial pressure transducer rated for 0 to 5000 psi gauge measurement with a 4-20 mA current-loop output. It uses a high-accuracy silicon strain-gage sensor molecularly bonded to a stainless-steel diaphragm, packaged in a rugged all-stainless-steel cylinder housing with a 1/4 inch NPT male process connection. A pressure transducer (also called a pressure transmitter) is an electromechanical sensor that converts an applied fluid or gas pressure into a proportional electrical signal for monitoring, control, or data acquisition. Within the broader sensor taxonomy it sits as: pressure sensor -> transducer -> industrial sensor -> measurement instrument. The 4-20 mA current-loop output is the dominant industrial standard because it is intrinsically safe over long cable runs and is immune to voltage drop on the wiring. Key features include 0.25 percent or 0.5 percent accuracy classes, long-term stability with low drift, an operating temperature range suited to process environments, and 316L stainless-steel wetted materials compatible with a wide range of media. The series spans gauge, absolute, compound-gauge, and vacuum pressure types, with selectable pressure ranges from a few psi up to 10,000 psi, making it a versatile workhorse for general-purpose industrial use. The PX309 below 100 psi uses an oil-filled isolation diaphragm that protects the silicon sensing element, while 100 psi and above units bond strain gages molecularly to the diaphragm directly. The all-welded stainless-steel construction provides excellent media compatibility and corrosion resistance, which is critical in hydraulic, chemical, and oil-and-gas applications where aggressive fluids would attack alternative elastomer-sealed sensors. Typical applications include HVAC system pressure monitoring, hydraulic system pressure feedback, process-control loops in chemical plants, pump and compressor monitoring, water and wastewater treatment pressure measurement, and factory-automation panels. When wiring this transmitter, supply 12 to 30 Vdc loop excitation, route the cable away from VFD inverters and large motors to minimize EMI, and use a 250-ohm sense resistor across the receiver input to convert 4-20 mA to 1-5 Vdc for older analog-input cards. This page synthesizes distributor pricing, application guidance, and a comparison with cross-brand alternatives that is not available in the stock Omega datasheet alone.
PX409 - 0.08% High Accuracy Pressure Transducer | Omega Engineering
The Omega Engineering PX409 is a configurable, high-accuracy pressure transducer that delivers ±0.08% accuracy with a 5-point NIST-traceable calibration certificate included with every unit. Built around a micro-machined silicon strain-gauge sensing element with all-stainless-steel wetted parts and welded construction, the PX409 series supports gauge, absolute, vacuum, differential, and compound pressure ranges from inches of water up to 10,000 PSI. Standard output options include 4-20 mA, 0-5 VDC, 0-10 VDC, ±10 VDC, USB, and RS-485, suiting both legacy analog loops and modern digital data-acquisition systems. A pressure transducer is a sensor that converts an applied fluid or gas pressure into a proportional electrical signal, typically voltage or current, for monitoring, control, or recording purposes. As a category, pressure transducers sit inside the broader hierarchy of pressure sensors -> sensors -> instrumentation -> industrial automation. Within that taxonomy, the PX409 is positioned as a high-accuracy, industrial-grade transmitter engineered for demanding test-stand, hydraulic, and process-control environments where traceability and long-term stability outweigh low-cost priorities. Key features include ±0.08% Best-Fit-Straight-Line (BFSL) accuracy, ±0.03% linearity option, all-stainless-steel 17-4 PH or 316L wetted parts, welded hermetic sealing, 3X full-scale burst pressure rating, and premium temperature compensation across a -20 °C to +85 °C operating range. The unit ships with a NIST-traceable calibration certificate documenting five calibration points across the pressure range, supporting ISO 17025 and calibration-quality requirements in regulated industries. Architecturally, the PX409 uses a micro-machined silicon diaphragm with a piezoresistive Wheatstone bridge. Onboard signal conditioning provides amplified, temperature-compensated output, eliminating the need for external instrumentation amplifiers in most applications. The robust mechanical design uses a 1/4" NPT male process connection as standard, with alternate fittings (1/2" NPT, 1/4" BSP, 7/16-20, SAE, or compression fittings) available via the factory configurator. Typical applications include hydraulic and pneumatic system monitoring, test and measurement instrumentation, fuel-pressure mapping on engine dynamometers, tank-level hydrostatic measurement, refrigeration and HVAC pressure monitoring, pharmaceutical and food-processing line verification, and cleanroom / laboratory gas-line verification. The 4-20 mA option is particularly suited to long cable runs and noisy industrial environments where voltage signals would otherwise suffer degradation. When integrating the PX409, observe the rated overpressure and burst specifications carefully. Hydraulic spikes and water-hammer events can exceed the rated pressure even when steady-state pressure is within range. For differential or vacuum models, keep the low-pressure side clean and dry; moisture ingestion is the most common service-life failure mode. This page synthesizes distributor pricing, datasheet specifications, drop-in alternative part options from the same Omega family, and practical installation guidance not consolidated on the manufacturer product page.
RO - Reverse Osmosis System | Standard RO Water Treatment
The RO Reverse Osmosis (RO) system is a water purification technology that removes dissolved ions, organics, particles, and microorganisms by forcing feed water through a semi-permeable membrane under pressure. RO membranes typically reject 95-99.5% of total dissolved solids (TDS) and produce permeate flows characterized by a steady-state flux rate in the L/m²/hr (LMH) range, depending on element geometry and operating pressure. Standard RO systems are packaged as 4040 (4-inch x 40-inch) or 8040 (8-inch x 40-inch) spiral-wound elements that fit industry-standard pressure vessels and operate between 1.0-1.5 MPa of feed pressure with up to 15% recovery per stage. An RO membrane element is a separation device within the broader water-treatment hierarchy: RO element → thin-film composite membrane → spiral-wound module → RO system → water purification unit → industrial process subsystem. Reverse osmosis (also called hyperfiltration) is distinguished from nanofiltration (NF) by its near-total ionic rejection, from ultrafiltration (UF) by its ability to remove monovalent salts, and from microfiltration (MF) by its ability to remove dissolved species below 1 nm. Key features of standard RO elements include thin-film polyamide composite membranes laminated onto a microporous polysulfone support, a 28-mil or 34-mil feed spacer, a permeate tube sealed by anti-telescoping device (ATD) end caps, and a standard 1.125-inch (4040) or 3.875-inch (8040) outer diameter. Most elements carry NSF/ANSI 61 certification for potable water contact and operate across a feed pH window of 2-11 (continuous) and 1-13 (cleaning), with maximum feed water temperature of 45°C and free chlorine tolerance of less than 0.1 mg/L. The polyamide chemistry provides the dense skin layer responsible for ionic rejection, while the polysulfone layer provides mechanical strength. Rejection is driven by solution-diffusion through the dense layer, with the support layer providing only hydraulic permeability. Operating pressure, recovery, and feed water chemistry (TDS, pH, temperature) jointly determine permeate quality and flux. Typical applications of standard RO elements include brackish water desalination (BWRO), seawater desalination (SWRO at higher pressure), ultrapure water for semiconductor and pharmaceutical manufacturing, boiler feed pre-treatment in power generation, food and beverage concentration/dewatering, and residential point-of-use drinking water. The wide feed-tolerance range supports single-stage and two-stage process trains. When designing with standard RO elements, size the high-pressure pump to deliver feed pressure above the osmotic pressure of the concentrate, plus the net driving pressure required for the design flux. Always include cartridge filtration (5 micron nominal) upstream of the RO train and avoid operating continuously above 15% recovery per element to prevent scaling and fouling.
SLB - Stainless Steel Single-Ended Beam Load Cell | Flintec
The Flintec SLB is a high-accuracy, low-profile, single-ended bending-beam load cell with full stainless-steel construction and potted environmental sealing, designed for tough industrial weighing applications. The SLB is offered in five capacities: 200 lb, 500 lb, 1,000 lb, 2,500 lb, and 5,000 lb (91 kg to 2,268 kg metric equivalents), making it one of the most flexible bending-beam families on the market. According to the Flintec SLB datasheet, the device carries an OIML R60 accuracy class rating with up to C3 (3,000 verification intervals) and is NTEP-rated for legal-for-trade use, which is unusual for a beam cell in this capacity range. A bending-beam load cell is a force transducer that converts an applied mechanical load into a measurable electrical signal via strain gauges bonded to a metal element that deflects proportionally under load. The SLB belongs to the broader category of strain-gauge load cells, which sit within the sensor hierarchy of load/force sensors -> weighing sensors -> industrial measurement transducers -> sensors. Bending-beam cells are typically used in tank, hopper, platform, and process-scale installations where low profile, hermetic sealing, and high repeatability are required. Key features of the SLB include 17-4 PH stainless-steel construction, hermetically sealed to IP67/IP68, a six-core shielded cable with strain-relief boot, integrated overload protection to approximately 150% of rated capacity, and laser-welded strain-gauge sealing that eliminates potting failures in humid or wash-down environments. The cell uses a four-wire (plus sense) bridge configuration with a nominal 2 mV/V output and 350-ohm bridge impedance, allowing direct connection to most industrial weight indicators and PLCs. Typical applications include truck and rail scales, batching and mixing hoppers, tank and silo weighing, in-process checkweighing, and OEM platform scales. The SLB's wide capacity range lets one mechanical design replace several single-capacity beam cells across a product line. When installing the SLB, use self-aligning mounting hardware to prevent side-load errors, and torque mounting bolts to the values listed in the datasheet to avoid preload shifts that compromise zero stability.
XMLP025BC11F - 25 bar Pressure Sensor, 0.5-4.5V, G1/4 | Schneider
The Schneider Electric XMLP025BC11F is a 25 bar electronic pressure transmitter from the OsiSense XM family, providing a 0.5 V to 4.5 V ratiometric analogue output over a G1/4 A male process connection conforming to DIN 3852-E. It operates from a 5 VDC SELV supply, draws 7 mA, and integrates a 3-wire EN 175301-803-A (ex DIN 43650) connector for plug-and-play hydraulic and pneumatic installations. The device uses a strain-gauge thin-film sensing cell with FPM (Viton) sealing for media compatibility from -30 °C to +135 °C. A pressure sensor is a transducer that converts an applied fluid pressure into a proportional electrical signal, and within the broader sensor taxonomy it belongs to the measurement-sensor family alongside temperature, flow, and level sensors. In an industrial control hierarchy, the XMLP pressure transmitter typically feeds an analogue input module of a PLC, a SCADA remote terminal unit, or a microcontroller-based data-acquisition front end, providing real-time hydraulic or pneumatic pressure data for closed-loop control and condition monitoring. Key differentiating features of the XMLP025BC11F include a wide 0 bar to 25 bar operating range with proof pressure of 75 bar and burst pressure of 150 bar, ±0.1 % repeatability per IEC 61298-2, ±1 % linearity (typical), and ratiometric 0.5-4.5 V output that cancels 5 V supply drift. The compact stainless-steel body with FPM seal supports air, fresh water, hydraulic oil, gas, and refrigeration fluids, eliminating the need for separate sensor SKUs per media type. The robust EN 175301-803-A connector supports field replacement without rewiring. At the silicon level the XMLP series relies on a piezoresistive Wheatstone bridge diffused into a stainless-steel diaphragm, laser-trimmed for offset and span, then conditioned by an Application-Specific Integrated Circuit (ASIC) providing ratiometric output, reverse-polarity protection, and short-circuit safeguards. The amplifier stage is calibrated so that 0.5 V corresponds to 0 bar and 4.5 V corresponds to 25 bar with a typical linearity of ±0.5 % of the full scale. The device is supplied with a traceability code per Schneider lot conventions and conforms to CE, UL, and CCC features. Typical applications include hydraulic-press pressure verification on machine tools, HVAC chilled-water and refrigerant line monitoring, compressed-air system pressure trending, injection-moulding clamp force feedback, and pump-discharge pressure supervision. In each case the 0.5-4.5 V ratiometric signal interfaces directly with industrial analogue inputs that expect a 0-5 V or 0-10 V proportional reading. When designing with the XMLP025BC11F, observe the 75 bar proof-pressure limit during transients such as water-hammer events, ensure the 5 V supply regulation stays within ±0.25 V to preserve ratiometric accuracy, and torque the G1/4 male fitting to 25-30 N·m using a thread sealant compatible with FPM/Viton. This part is now in end-of-commercialization status as of May 31, 2023, so design-in for new projects should target the active XMLP platform variants such as XMLP025BC71F.
