MPXV2010GP 概要
A piezoresistive pressure sensor is a MEMS device in which a monolithic silicon diaphragm and an integrated strain-gauge resistor network convert mechanical pressure into a millivolt-level analog voltage. The MPXV2010GP sits in the hierarchy of: pressure transducer -> MEMS pressure sensor -> signal-conditioning sensor -> sensor IC. The on-chip thin-film resistor network is laser-trimmed for span, offset, and temperature compensation, which removes the need for external calibration and simplifies firmware-side linearization in host MCUs.
Key features include a 0–10 kPa operating range, 25 mV full-scale span at 10 V excitation, 1.0 kPa typical pressure hysteresis, an integrated temperature compensation network, and ratiometric output that tracks supply voltage. The case 344B-01 package (8-SMD, gull-wing, side port) provides a robust surface-mount form factor with the pressure port on the package side, enabling vertical pneumatic coupling through a single 3.17 mm (0.13") tube barbed inlet.
The MPXV2010GP uses a monolithic silicon diaphragm with a Wheatstone-bridge strain-gauge configuration; bridge excitation at 10 V DC produces a differential millivolt signal proportional to differential pressure. The trimming process calibrates each device at room temperature and 0/10 kPa, with downstream accuracy dependent on the chosen ADC resolution and reference, and on conditioning the output through an instrumentation amplifier before MCU sampling.
Typical applications include HVAC differential pressure monitoring, medical respirators and ventilators, industrial process control, air-flow measurement in variable-air-volume (VAV) boxes, and low-pressure process instrumentation where 0–10 kPa sensing with a clean vented reference is required. The vented gauge reference makes the device well-suited to barometric-style measurements where backside absolute-pressure artifacts must be excluded.
When designing with the MPXV2010GP, use a low-impedance instrumentation amplifier at the sensor output to preserve the mV-level signal and reject common-mode noise, and place a 0.01 uF bypass capacitor close to the supply pin. The output is ratiometric, so using a stable, low-noise 10 V reference yields the best full-scale accuracy.

主な用途
MPXV2010GP の用途: 6 件s: HVAC Differential Pressure Monitoring, Medical Respirator and Ventilator Pressure Sensing, Industrial Process Air-Flow Measurement, Barometric Reference and Altitude Compensation, Liquid-Level and Column-Pressure Sensing, Pneumatic Leak Testing and Inline Quality Control.
HVAC Differential Pressure Monitoring
The MPXV2010GP fits HVAC pressure monitoring because its 0-10 kPa range covers filter-loading and duct static-pressure drop common in commercial air-handling units (0.05-1.5 inH2O is ~12-370 Pa). With 25 mV full-scale span at 10 V excitation and 1.0 ms response time, the device tracks pressure transients during fan startup and filter-clog events in real time. Placed across a Honeywell or differential orifice with an INA128 instrumentation amplifier feeding a 16-bit ADC, it replaces bulkier industrial differential transducers in VAV box controllers. Estimated: for a 0-250 Pa air-flow map, the sensor adds 0.1 Pa resolution after the instrumentation stage, more than adequate for building-automation loops.
おすすめ
Medical Respirator and Ventilator Pressure Sensing
The MPXV2010GP is well suited to ventilator circuit-pressure sensing in the 0-100 cmH2O (~0-10 kPa) range, where its 1.0 kPa hysteresis and 1 ms response time let the host MCU detect patient-circuit occlusion and peak inspiratory pressure within one breath cycle. Its calibrated, temperature-compensated output simplifies FDA documentation by removing external potentiometer trim steps. With a 10 V low-noise LDO, an isolation amp (ISO124), and two redundant MPXV2010GP sensors in parallel, designers meet IEC 60601 alarm requirements for breach detection. The vented-gauge reference prevents barometric drift in portable units used at varying altitudes.
おすすめ
Industrial Process Air-Flow Measurement
The MPXV2010GP enables compact air-flow measurement in variable-air-volume (VAV) boxes, laminar-flow hoods, and cleanroom pressure tracking where 0-10 kPa is the typical differential across orifice plates or Pitot pickups. Its 2.5 mV/kPa nominal sensitivity pairs naturally with a 16-bit delta-sigma ADC front end for sub-Pascal resolution. The 8-SMD side-port package fits a compact sensor head with a single 3.17 mm pneumatic inlet, eliminating the manifold plumbing of legacy through-hole MPX2010 designs. Estimated: through an INA2331 zero-drift amplifier, the MPXV2010GP delivers better than 0.5% FS accuracy at room temperature, suitable for ISO 14644 cleanroom monitoring.
おすすめ
Barometric Reference and Altitude Compensation
The MPXV2010GP's vented-gauge reference makes it the right pick for altitude-compensation tasks in drones, weather stations, and portable GPS where barometric drift would otherwise force software compensation. By referencing the back side of the diaphragm to ambient via the side-port vent, the device rejects absolute-pressure changes due to weather and elevation. Compared to 50 kPa absolute sensors the MPXV2010GP sacrifices top-end range but resolves pressure differentials down to about 1 Pa after amplification, ideal for vertical-speed indicators in small UAVs.
おすすめ
Liquid-Level and Column-Pressure Sensing
The MPXV2010GP is used in low-head liquid-level sensing (under 1 m of water, ~10 kPa) such as dialysis machines, household water softeners, and small chemical tanks. Its 25 mV span at 10 kPa allows simple conditioning for hydrostatic column readouts, and the vertical 3.17 mm side port accepts standard rigid tubing directly on the package. The vented-gauge topology cancels atmospheric pressure variation, so changes in weather do not show up as drift in tank-level readings. Designers often pair two MPXV2010GP units as a redundant pair for medical-class fault detection.
おすすめ
Pneumatic Leak Testing and Inline Quality Control
Inline leak-test fixtures in automotive component plants and consumer-electronics factories use the MPXV2010GP because of its 0-10 kPa range and millisecond response. By pressurizing a sealed device under test to a fixed set-point and watching the MPXV2010GP output, the controller can detect leak rates as small as 1 Pa/s - far below what slower legacy gauges can resolve. The 8-SMD package drops onto a small test fixture PCBA alongside a solenoid-driver stage, and the ratiometric output scales directly with the regulated 10 V rail supplied to the solenoid, simplifying calibration. Estimated: with a 0.01 uF bypass and a 100 Hz LPF, the device settles within 5 ms after a step, ideal for 200 ms test cycles.

設計ノート
Estimated: with a 25 mV full-scale output at 10 V excitation, route the MPXV2010GP differential output over a twisted pair or guard-trace pair to an INA128 instrumentation amplifier. Place the 0.01 uF supply bypass within 5 mm of the Vs pin to suppress switching-noise injection from neighboring DC-DC converters. Without a proper instrumentation amp, EMI from the host MCU's 16 MHz clock can couple capacitively into the bridge and produce 5-10 mV of spurious noise, equivalent to 2-4 kPa of pressure error.
Do not block the side-port vent on pin 8 of the MPXV2010GP. The vented-gauge reference relies on free airflow to atmosphere; sealing the port with epoxy or potting gel destroys the gauge topology and causes the output to drift with barometric pressure. Apply a 25 um hydrophobic membrane if the application is dust or splash exposed, but never wet-solder the side port.
Use a stiff, low-impedance PCB cutout around the MPXV2010GP side-port pad to avoid mechanical stress that the silicon diaphragm translates into offset. Keep tall capacitors and connectors at least 3 mm from the side port to maintain the required 0.13" (3.17 mm) tube clearance. Ground plane integrity around the bridge is essential; split or chopped planes that pass under the bridge traces inject thermal-EMF noise proportional to local temperature gradients.
The on-chip temperature-compensation network specifies 1.0 kPa hysteresis and a compensated temperature range of -40 C to +125 C. Estimated: for medical and HVAC deployments, a 30 second warm-up after power-on is sufficient for the laser-trimmed resistor network to settle; do not calibrate until 60 seconds in. Add a non-zero minimum airflow over the sensor in enclosed housings to avoid thermal-soak drift above +85 C in closed enclosures.
