MPX2010GSX - 10kPa Pressure Sensor, 4-SIP, STMicroelectronics
MPN： MPX2010GSX ✓ 啟用中MPX2010GSX 概覽
Pressure sensors like the MPX2010GSX are transducers that convert an applied pressure into a proportional electrical signal. Within the broader sensor hierarchy they belong to MEMS (Micro-Electro-Mechanical Systems) devices, and more specifically to piezoresistive pressure sensors - a category that uses strain-induced resistance changes in silicon to produce a Wheatstone-bridge output voltage. Unlike capacitive or optical pressure sensors, piezoresistive designs offer simple excitation (10 V typical), high linearity, and ratiometric output ideal for low-pressure medical and instrumentation applications.
Key features include 25 mV full-scale span at 10 V excitation, 0.45% linearity typical, 1.0 mV/kPa sensitivity, on-chip temperature compensation from 0°C to +85°C, and ratiometric output proportional to supply voltage. The 4-SIP package with axial tube port simplifies pneumatic interface, while the through-hole mounting provides robust mechanical retention on the PCB.
The MPX2010GSX uses a single monolithic silicon diaphragm with an integrated four-resistor Wheatstone strain-gauge bridge. Laser-trimmed resistors calibrate span and offset at room temperature, with additional thin-film compensation networks maintaining accuracy across the 0°C to +85°C operating range. Excitation at 10 V DC produces a ratiometric output that scales linearly with supply, simplifying ADC interface design.
Typical applications include medical respiratory monitoring (spirometers, ventilators), HVAC airflow sensing, industrial process control, and altimeter/barometric reference designs where the 0-10 kPa gauge range matches inhalation flow or low-differential process pressures.
When designing with this device, ensure a stable low-noise 10 V excitation supply; supply ripple directly couples into the output. The 0.19" tube port must be sealed against contamination and moisture, and the through-hole pins require strain relief if the pneumatic line applies mechanical load.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers shorten the selection and qualification cycle for 10 kPa vented-gauge pressure sensing.

典型應用
MPX2010GSX 適用於 6 應用s: Medical Respiratory Monitoring, HVAC Airflow & Filter Pressure Drop, Industrial Process Control & Manifold Pressure, Portable Altimeter / Barometric Reference, Pneumatic Control & Robotics, Appliance Pressure Sensing (White Goods).
Medical Respiratory Monitoring
The MPX2010GSX's 0-10 kPa range is ideal for spirometer and CPAP pressure measurement, where peak inhalation flow and mask pressure typically remain under 7.5 kPa (75 cmH2O). The 0.19" axial tube port accepts standard medical tubing without adapters, simplifying patient-circuit integration. The 1.0 mV/kPa sensitivity paired with 0.45% linearity delivers reliable breath-by-breath pressure tracking when read through an INA128 instrumentation amplifier with gain of 100. On-chip temperature compensation across 0°C to +85°C maintains calibration accuracy in heated enclosures. Unlike amplified digital sensors, the analog output lets the host MCU sample at >1 kHz, enabling flow-derivative calculations for spirometry waveform analysis.

HVAC Airflow & Filter Pressure Drop
The MPX2010GSX monitors filter pressure drop across HVAC return-air ducts and cleanroom terminal units, where 0-10 kPa covers typical loaded-filter thresholds (1-5 kPa) and pre-fan static pressure. The vented-gauge reference port prevents altitude drift in rooftop installations. The 4-SIP through-hole package mounts directly on the duct plenum PCB with the 0.19" tube extending into the air stream. For differential filter monitoring (pre vs post filter), two MPX2010GSX units feed a differential amplifier. Designers often pair the sensor with a C-grade op-amp gain stage (LM358 / MCP6002) and a 4-20 mA loop transmitter for industrial BMS integration.

Industrial Process Control & Manifold Pressure
Process-control instruments measuring low-pressure gas lines, vacuum pump inlet pressure, or natural-gas appliance manifold pressure benefit from the MPX2010GSX's ratiometric 25 mV/10V span and high immunity to common-mode noise. The 0-10 kPa gauge range aligns with industrial regulator set-points below 1.5 PSI. The through-hole 4-SIP package withstands vibration better than SMT pressure sensors in motor-control cabinets. On-chip temperature compensation reduces calibration drift across outdoor enclosures. The device is commonly used in gas chromatograph carrier-gas regulators and pneumatic control loops, where the piezoresistive bridge drives a panel meter or PLC analog input module.
推薦
Portable Altimeter / Barometric Reference
The MPX2010GSX serves as a low-cost barometric reference in portable altimeter designs and weather-station instruments where 0-10 kPa covers the full sea-level-to-3 km altitude span (approximately 70 kPa to 30 kPa absolute, but differential measurements against a sealed reference are feasible with paired sensors). The 1.0 mV/kPa sensitivity and 0.45% linearity translate to sub-meter altitude resolution when paired with a low-noise 24-bit ADC. The vented gauge port requires altitude correction through GPS or sea-level baseline, or differential sensing against a sealed reference. Its through-hole SIP package survives handheld drops better than fragile SMT sensors, making it a popular choice in hiking and amateur-rocket telemetry hardware.
推薦
Pneumatic Control & Robotics
Pneumatic robotics and pick-and-place vacuum systems use the MPX2010GSX to monitor suction cup pressure in the 0-10 kPa range typical of vacuum grippers and small diaphragm pumps. The fast mechanical response of the silicon diaphragm (sub-millisecond settling) enables closed-loop suction control for delicate object handling. The 4-SIP through-hole footprint mounts easily on DIN-rail pneumatic manifold PCBs. Designers integrate the sensor with a solenoid-driver MOSFET stage (e.g. IRF540N) and a PID loop on an STM32 or Arduino-class MCU. The 25 mV analog span scales cleanly into a 12-bit ADC input after a 100x instrumentation amplifier stage.

Appliance Pressure Sensing (White Goods)
The MPX2010GSX appears in water-heater inlet regulators, dishwasher flow sensors, and clothes-dryer duct-pressure monitors where 0-10 kPa covers the working range. The 0.19" tube port accepts standard 3/16" pneumatic hose used in appliance manifolds. The piezoresistive silicon die tolerates long-term thermal cycling better than polymer capacitive sensors, extending service life in hot-water and steam environments. The through-hole SIP package also simplifies conformal coating for moisture-prone dishwasher and washing-machine control boards. The 10 V ratiometric excitation interfaces directly with legacy appliance controller ADCs that share the same 10 V reference rail.

設計說明
Estimated: Excite the MPX2010GSX bridge with a low-noise 10 V reference such as REF01 or REF02. Bridge current at 10 V is approximately 6 mA - total power dissipation is 60 mW, so self-heating is negligible. Supply ripple couples directly into the 25 mV output, so add a 10 uF + 0.1 uF bypass network on the Vex pin. Ratiometric output scales linearly with supply, so a 5 V supply produces 12.5 mV span - useful for 3.3 V ADC designs with an INA gain of 250.
Estimated: The 25 mV full-scale span is small enough that PCB leakage and stray capacitance can introduce 1-2% error. Route the four bridge pins as a tight quad with ground guard ring around Vout+ and Vout- traces. Keep bridge traces away from switching power or PWM lines (cross at right angles if needed). Use a low-bias-current instrumentation amplifier (INA128, AD620, or INA333 for portable designs) with input bias current under 5 nA to avoid drift. Estimated input offset voltage of 50 uV corresponds to 0.05 kPa error, comparable to sensor linearity.
Do not reverse Vex and GND - the device is not internally polarity-protected and reverse excitation will damage the bridge. Do not apply pressure exceeding 2x rated range (20 kPa) or the diaphragm may fracture. For 0.19" tube port applications, avoid kinking or sharp bends in the pneumatic line; use flexible silicone tubing. The vented-gauge reference port on the rear of the package must remain open to atmosphere - do not seal the entire device in potting compound.
