MPX2100GVP Visão geral
A pressure sensor is a transducer that converts an applied mechanical pressure into a proportional electrical signal. Within the broader sensor hierarchy, piezoresistive silicon pressure sensors belong to the MEMS (Micro-Electro-Mechanical Systems) family, which sits under the wider category of physical sensors and ultimately under signal-conditioning and data-acquisition components. These devices typically rely on a Wheatstone-bridge network diffused into a silicon diaphragm; when pressure deflects the diaphragm, the bridge resistors change value and produce a differential output. On-chip temperature compensation maintains accuracy across commercial and industrial temperature ranges, eliminating the need for external linearization in many designs.
The MPX2100GVP integrates the sensing element, signal conditioning, and temperature compensation on a single silicon die. Its full-scale span of 40 mV is calibrated directly by the manufacturer, simplifying the host-side interface to a simple ADC channel or instrumentation amplifier. Operating from a 10 V typical supply (3 V minimum specified for the family, full performance at 10 V), the part draws only 6 mA. The 4-SIP through-hole package with ported tube inlet simplifies hose/fitting integration in industrial equipment, medical instrumentation, and HVAC systems. Maximum operating temperature reaches 125 degrees Celsius, supporting engine-bay and process-control environments.
Typical applications include pneumatic control systems, respiratory and medical monitoring equipment, gas-flow instrumentation, altimeters and barometric measurement, and industrial process controllers. The vented-gauge topology means absolute vacuum reads as 0 kPa, and the device rejects common-mode supply noise due to its bridge output structure.
When designing with the MPX2100GVP, place a precision instrumentation amplifier (such as an INA125 or AD620) immediately after the sensor output to boost the millivolt-level signal before it reaches the ADC. Add adequate EMI/RFI shielding because the high-impedance bridge output is susceptible to interference. Provide a clean, regulated supply because output is ratiometric to supply voltage.

Aplicações típicas
MPX2100GVP é adequado para 7 aplicaçãos: HVAC Duct and Building Pressure Monitoring, Medical Respiratory and Spirometer Equipment, Industrial Pneumatic Control and Valve Feedback, Barometric Measurement and Altimeter Systems, Filter Clog and Air-Flow Differential Sensing, Process Control and Tank-Level Measurement, Weather Station and Environmental Monitoring.
HVAC Duct and Building Pressure Monitoring
The MPX2100GVP suits HVAC duct pressure and building pressure monitoring because its 0 to 100 kPa vented-gauge range matches typical building-pressure spreads and its 0.19 inch (4.93 mm) male tube port accepts standard pneumatic hose fittings used in air-handling units. On-chip temperature compensation keeps readings stable across -40C to +125C rooftop and mechanical-room environments, while the bridge output typically feeds an instrumentation amplifier such as INA128 before the building automation ADC. Compared with differential-pressure flow sensors using orifice plates, the MPX2100GVP provides direct static-pressure readout with 40 mV span at 10 V supply, simplifying calibration. Designers should mount the ported inlet facing downward to reduce moisture ingress in ductwork.
Recomendado
Medical Respiratory and Spirometer Equipment
The MPX2100GVP fits respiratory monitoring, spirometers, and CPAP/BiPAP pressure verification because its 0 to 100 kPa range covers mouth and airway pressure envelopes while on-chip compensation maintains accuracy as the device warms during patient use. The ported inlet accepts standard respiratory tubing, and the bridge output is amplified by an AD620 or INA125 to drive a 16-bit ADC. The vented-gauge topology means atmospheric changes cancel out, important for handheld spirometers. Compliance with IEC 60601-1 medical safety standards remains the integrator's responsibility, and the sensor should be isolated from patient-contact paths. Compared with disposable flow sensors, the MPX2100GVP offers better long-term stability across repeated calibration cycles.
Recomendado
Industrial Pneumatic Control and Valve Feedback
The MPX2100GVP is widely deployed in pneumatic control systems where 0 to 100 kPa covers most factory compressed-air and actuation pressures. The vented-gauge reference rejects altitude-dependent absolute readings, simplifying valve-position and actuator-force feedback loops. The 4-SIP through-hole package with male tube port snaps into standard industrial manifolds, and the 40 mV full-scale span interfaces directly with PLC analog input modules after instrumentation amplification. The on-chip temperature compensation reduces drift in factory environments with 10C to 50C swings, while the 125C maximum rating supports engine-bay and process-control cabinets. Compared with strain-gauge pressure transducers, the MPX2100GVP delivers a calibrated millivolt output that eliminates potentiometer trimming.
Recomendado
Barometric Measurement and Altimeter Systems
For altimeters and weather-station barometric measurement, the MPX2100GVP vented-gauge topology lets the host subtract local sea-level pressure to derive altitude, while its 100 kPa range envelops all earthly pressures. The 40 mV span at 10 V drives an ADC with adequate headroom, and the on-chip compensation minimizes temperature-induced altitude errors that could otherwise produce 10-meter or larger biases. Unmanned aerial vehicle flight controllers often use the MPX2100 family for sensor-fusion altitude estimation, where the small 4-SIP size and 6 mA supply current fit tight weight and power budgets. Compared with absolute-pressure sensors, the MPX2100GVP avoids the vacuum-reference aging drift common in sealed-cavity designs.
Recomendado
Filter Clog and Air-Flow Differential Sensing
The MPX2100GVP detects HVAC and dust-collection filter clogging by sensing the pressure drop across a filter element as airflow restrictions increase. With 0 to 100 kPa range and on-chip compensation, the sensor delivers stable readings across the lifetime of a clogged filter. Two sensors mounted across a filter bank feeding an instrumentation amplifier produce a differential clog indicator, signaling maintenance crews before airflow degradation impacts downstream processes. The vented-gauge configuration accommodates changes in absolute barometric pressure without false alarms, important for outdoor installations. Compared with mechanical pressure switches, the MPX2100GVP provides continuous analog readout for trend logging and predictive maintenance.
Recomendado
Process Control and Tank-Level Measurement
In process-control panels, the MPX2100GVP monitors low-pressure vessels and bubbler-type tank-level systems where 0 to 100 kPa covers most head pressures for non-pressurized tanks. The sensor sits at the bottom of the pneumatic dip tube, and the vented reference corrects for local barometric changes that would otherwise bias tank-level readings. Host PLCs digitize the 40 mV span via 16-bit ADCs and derive tank volume from the calibrated relationship between head pressure and hydrostatic level. The on-chip temperature compensation keeps measurement drift under 1 percent across typical ambient swings, while the 4-SIP module with tube port simplifies plumbing integration. Compared with hydrostatic capacitance probes, the MPX2100GVP avoids contact with corrosive tank contents.
Recomendado
Weather Station and Environmental Monitoring
The MPX2100GVP serves hobbyist and professional weather stations as a barometric pressure element, where its 0 to 100 kPa range covers normal sea-level to high-altitude pressures and the 40 mV span drives a microcontroller ADC through a small instrumentation amplifier. The vented-gauge topology gives real atmospheric pressure without vacuum-reference drift, while on-chip compensation maintains accuracy across temperature swings from -40C winter cold to +125C summer sun in sealed enclosures. Combined with an external temperature/humidity sensor, the MPX2100GVP forms the core of a multi-parameter weather station logging to SD card or wireless uplink. Compared with modular weather chips, the discrete MPX2100GVP provides repairability and replaceability in long-deployment field stations.

Notas de projeto
Place a precision instrumentation amplifier (such as INA128, AD620, or INA333) within 50 mm of the MPX2100GVP output pins to minimize pickup on the high-impedance millivolt-level bridge signals. Use a guard trace or twisted-pair routing for VOUT+ and VOUT- to reject common-mode noise, and locate the sensor away from switching regulators, motor drivers, and relay coils. Apply RFI suppression capacitors (1 nF to 10 nF) at the amplifier inputs if the sensor cable runs more than 100 mm. Source: NXP MPX2100 datasheet typical application circuit.
The MPX2100GVP is ratiometric, so output span scales linearly with supply voltage; use a low-noise regulated supply (LM317 or REF02-based 10 V rail) rather than raw rectified DC. Add 100 nF ceramic and 10 uF electrolytic decoupling within 25 mm of the VCC pin. Bridge current consumption is approximately 6 mA, so a small 78M10 or DC-DC followed by LDO easily handles the load while keeping noise below 100 uVpp.
Although the MPX2100GVP integrates on-chip temperature compensation, host designs should still shield the sensor from direct airflow or radiation sources to avoid thermal gradients across the diaphragm. In outdoor enclosures, mount the sensor away from solar-heated surfaces and use thermal-conductive epoxy to couple (or decouple as appropriate) from the PCB. Operating temperature spans -40C to +125C, allowing engine-bay and refrigerated applications without external heating or cooling.
Do not apply pressure beyond the 100 kPa full-scale or pressure transients exceeding the burst rating, or the silicon diaphragm may fracture. Avoid sealing the vented-gauge port because that converts the topology to absolute, invalidating readings. Do not probe the bridge output with a long ground-lead oscilloscope clip - use a differential probe or buffer the signal first.
