MPX2010GS 概述
A piezoresistive pressure sensor is a transducer whose conversion of mechanical pressure into an electrical signal relies on a silicon diaphragm embedded with diffused Wheatstone-bridge resistors; when pressure deflects the diaphragm, the bridge imbalance produces a differential output proportional to the applied pressure. The MPX2010GS belongs to the board-mount pressure-sensor family within the broader transducer (sensor -> pressure sensor -> piezoresistive sensor -> gauge pressure sensor -> silicon pressure sensor) taxonomy and is commonly used wherever a small, linear, temperature-stabilized pressure-to-voltage conversion is required.
Key differentiating specifications include an operating pressure range of 0 to 10 kPa (0 to 1.45 psi), an output of 0 mV to 25 mV at 10 V, a Wheatstone-bridge analog output type, vented-gauge pressure type referenced to atmosphere, on-chip temperature compensation and calibration, and a 10 V to 16 V supply range. The integrated signal conditioning, calibration, and temperature compensation eliminate external compensation networks and reduce BOM count.
At its core, the MPX2010GS uses a single-element piezoresistive die laser-trimmed for span and offset, with on-chip compensation networks (resistors) flat across the 0 to 85 C operating range. The hermetic SIP-4 housing isolates the die from ambient humidity and provides a barbed tube port for pneumatic connection, with a vent port to atmosphere providing gauge (vs. absolute or differential) reference. Compared with uncompensated bare-die sensors, the integrated compensation substantially reduces system-level drift error.
Typical applications include medical respirators and ventilators, HVAC variable-air-volume (VAV) controllers, industrial process controllers, barometric/altimeter instrumentation, level measurement, and consumer appliances such as washing-machine water-level sensors. The 10 kPa range suits low-pressure medical and HVAC use cases where barometric noise would otherwise swamp a higher-range transducer.
When designing with the MPX2010GS, place an instrumentation amplifier (e.g., INA125, AD620, or NXP MPXAZ5010 interface) directly at the Wheatstone output to convert the millivolt bridge signal to a usable 0-5 V or 4-20 mA signal. Use a stable, low-noise excitation source (10 V typical) because sensor span scales linearly with excitation; noise and drift on the supply will be reflected in the output. Apply a bypass capacitor near the supply pin.

典型应用
MPX2010GS 适用于 6 应用s: Medical Ventilator and Respirator Pressure Monitoring, HVAC Variable Air Volume (VAV) Box Control, Barometric Pressure and Altimeter Instrumentation, Industrial Process Controller Low-Pressure Loop, Washing Machine and Dishwasher Water Level Sensing, Robotic and Drone Airspeed / Pitot-Static Sensing.
Medical Ventilator and Respirator Pressure Monitoring
The MPX2010GS is well suited to medical ventilator and respirator pressure monitoring because its 0-10 kPa (1.45 psi) range matches the low airway-pressure transients found in CPAP, BiPAP, and anesthesia circuits. Its on-chip temperature compensation from -40C to +125C keeps span and offset drift within +/-1% across clinical thermal environments, while the Wheatstone-bridge 0-25 mV output at 10 V excitation is easily amplified to a usable 0-5 V rail by an INA125 instrumentation amplifier placed adjacent to the SIP port. Unlike higher-range transducers, the MPX2010GS gives millibar resolution at the typical 5-30 mbar breathing pressure without saturating the front end, and its vented reference inherently rejects barometric shifts that would otherwise appear as patient-pressure error.
推荐
HVAC Variable Air Volume (VAV) Box Control
The MPX2010GS fits HVAC variable-air-volume box control where duct differential pressure typically ranges from 0 to 1.5 inches water column (about 0.4 kPa full-scale). With its 0-10 kPa range and 2.5 mV/kPa sensitivity, the sensor resolves fractions of a Pascal at the low signal levels where VAV controllers operate, while its vented-gauge reference auto-compensates for altitude and barometric shifts in rooftop installations. The 4-SIP barbed tube port accepts standard 4.93 mm pneumatic tubing used in duct manifolds, and the 10-16 V supply range aligns with 24 VAC-rectified control boards. The +/-1% calibrated accuracy is sufficient for closed-loop damper control without on-board linearization.
推荐
Barometric Pressure and Altimeter Instrumentation
For hobbyist altimeters, drone altitude hold, and weather-station barometers, the MPX2010GS provides a calibrated 0-10 kPa gauge output that is conveniently zero-referenced at sea level through its vent port. The 2.5 mV/kPa sensitivity gives roughly 25 microvolts per meter of altitude change near sea level when read with a low-noise 24-bit ADC (e.g., ADS1220), enabling sub-meter altitude resolution without external amplification. The hermetic SIP-4 housing protects the silicon diaphragm from humidity and condensation encountered in outdoor enclosures, and the on-chip temperature compensation suppresses the 0-25 mV output drift that would otherwise corrupt altitude readings across a -20C to +60C weather range.
推荐
Industrial Process Controller Low-Pressure Loop
The MPX2010GS serves in industrial process controllers monitoring low-pressure gas or pneumatic lines in the 0-10 kPa range, such as cleanroom pressure cascades, glove-box overpressure regulation, and natural-gas leak detection circuits. Its calibrated 0-25 mV bridge output integrates directly with 4-20 mA loop transmitters built around XTR105 or XTR106, allowing two-wire industrial transmission back to PLCs and DCS systems. The 10-16 V supply range is compatible with 24 VDC industrial rails, and the SIP mounting with barbed port simplifies pneumatic plumbing in standard 4.93 mm tubing manifolds common in process skids.
推荐
Washing Machine and Dishwasher Water Level Sensing
Consumer washing machines and dishwashers use the MPX2010GS for water-level (or air-trapped pressure) sensing, where 0-10 kPa covers the typical 0-1 m water column range. The vented-gauge reference automatically subtracts atmospheric pressure, so day-to-day barometric shifts do not affect fill-level calibration. The on-chip temperature compensation handles the 5C-60C wash-water environment without recalibration, and the 4-SIP barbed port connects directly to the air-trap tube used in appliance sump designs. The MPX2010GS is a higher-accuracy alternative to the discrete pressure-switches used in legacy designs, supporting multi-level wash programs via software-level thresholds.
推荐
Robotic and Drone Airspeed / Pitot-Static Sensing
Low-cost robotic and drone platforms use the MPX2010GS as a Pitot-static airspeed sensor where differential pressure across a venturi rarely exceeds 5 kPa even at 30 m/s flight speeds. Mounted in a 4-SIP module, the sensor's small footprint and barbed port simplify integration into air-data booms, and its calibrated millivolt output feeds directly into op-amp-based airspeed calculators before the MCU's ADC. The vented-gauge reference is critical here: it lets the back-side of the diaphragm see ambient (static) pressure while the front side sees stagnation (total) pressure, yielding true differential pressure when the two ports are connected to the appropriate Pitot tube taps.

设计说明
The MPX2010GS bridge output span scales linearly with excitation voltage: a 10 V regulated source is the standard calibration reference and yields 25 mV full-scale at 10 kPa; a 16 V source raises full-scale to roughly 40 mV. Any noise or drift on the excitation voltage is reflected directly in the output, so use a low-noise LDO (e.g., LP2985, TPS7A47) rather than a switching regulator for the bridge supply. Place a 100 nF ceramic bypass capacitor within 5 mm of pins 3 and 4.
The 0-25 mV bridge signal is small and easily corrupted by thermocouple effects and ground loops. Use an instrumentation amplifier (e.g., INA125, AD620) placed adjacent to the SIP module with twisted-pair or shielded routing from pins 1 and 2 to the INA inputs. Estimated: for the MPX2010GS at 2.5 mV/kPa and an INA125 with gain 100, expect roughly 2.5 V full-scale output per 10 kPa, well-suited to a 0-5 V ADC input.
Do not apply pressure exceeding the maximum overpressure rating of the MPX2010GS - the die or housing will rupture. Do not confuse the MPX2010GS (vented gauge) with the MPX2010DP (differential) - they are electrically drop-in but pneumatically incompatible. Do not power the sensor below 10 V or above 16 V; below 10 V the output span scales down proportionally and the S/N ratio suffers; above 16 V the die may overheat and the calibration shifts.
Mount the MPX2010GS vertically with the barbed port pointing upward to prevent condensate from pooling on the silicon diaphragm. Keep the vent holes on the SIP housing clear of conformal coating or potting compound - blocked vents destroy the gauge reference. Provide strain relief for the pneumatic tubing so vibration cannot fatigue the barbed port.
