MPX5010D 概要
A piezoresistive transducer is a solid-state sensor that converts applied mechanical pressure into a proportional change in resistance of diffused silicon strain gauges arranged in a Wheatstone bridge. The MPX5010D belongs to the pressure-sensor / transducer family in the broader Sensors hierarchy, which itself sits within MEMS (Micro-Electro-Mechanical Systems). The integration of signal conditioning, temperature compensation and calibration directly on-chip distinguishes this part from raw Wheatstone-bridge sensing elements that require external amplifiers and trimming.
Key features include a 0.2 V to 4.7 V ratiometric analog output proportional to 5 V supply, a 4.75 V to 5.25 V supply range, a typical full-scale span of 4.5 V at 10 kPa, and a measured accuracy suitable for medical, industrial and consumer flow or level sensing applications. The device is engineered to interface directly with microcontrollers or microprocessors equipped with A/D inputs, eliminating the need for additional front-end analog circuitry in most designs.
At the architecture level the sensor combines advanced surface micromachining, thin-film metallization for the strain-gauge network, and bipolar signal-conditioning circuitry fabricated on the same silicon die. Temperature compensation and span calibration are laser-trimmed at the wafer level, so each part delivers a closely-matched transfer function across the 0C to +85C operating range. The differential pressure port geometry routes positive pressure to the top side of the diaphragm and reference pressure to the underside.
Typical applications include HVAC duct airflow measurement, medical respirator and ventilator flow paths, liquid level detection in non-corrosive reservoirs, industrial process control loops, barometric baseline correction in altimetry modules, and appliance water-level feedback. The differential configuration enables bidirectional flow sensing across an orifice or venturi element.
When designing with the MPX5010D, place a 0.1 uF decoupling capacitor within a few millimeters of the supply pin and use a stable 5 V reference for the ADC if absolute pressure accuracy beyond the ratiometric spec is required. Avoid exposure to harsh media - the silicon diaphragm is exposed through the port and should be protected with a compatible media-isolating cap in liquid applications.

HVAC Duct Airflow Measurement
The MPX5010D's 0 to 10 kPa differential range matches the pressure drop produced by a small orifice or pitot tube in HVAC ducts, while its calibrated 0.2 V to 4.7 V ratiometric output can be sampled by a microcontroller ADC without additional analog front-end circuitry. Placing the sensor across a known restriction allows the host MCU to compute flow using the standard Q proportional to sqrt(DeltaP) relationship; the on-chip temperature compensation holds accuracy across the 0C to +85C supply-air range with no external drift trim, though bypass capacitance should be placed within a few millimeters of the supply pin to suppress ADC noise coupling.
おすすめ
Medical Respirator Flow Path
For medical ventilator and CPAP flow paths the MPX5010D provides a low-noise, conditioned analog signal that is normally summed with reference-side pressure to derive patient flow. The silicon diaphragm is air-referenced and dry-media compatible, simplifying the pneumatic isolation stack; the 4.5 V full-scale span over 10 kPa yields a 4.5 mV/Pa resolution on a 12-bit ADC, sufficient for breath-shape analysis. Designers must add media-isolation and sterilization interfaces suitable for the clinical deployment because the silicon diaphragm is exposed through the port.
おすすめ
Liquid Level Detection in Reservoirs
The MPX5010D works as a non-corrosive liquid level sensor when the high-pressure port is connected via an air column to the bottom of the tank, while the low-pressure port vents to atmosphere. The hydrostatic pressure scales linearly with liquid height, so a 10 kPa full-scale range corresponds to about 1 meter of water column at typical system factors; the ratiometric 0 to 4.7 V output feeds a 12-bit ADC for continuous level telemetry. Confirm media compatibility because the die is exposed and the part is intended for dry-gas pressure coupling only.
おすすめ
Industrial Process Control Loops
In industrial 4 mA to 20 mA loops and PLC analog inputs, the MPX5010D delivers a 0.2 V to 4.7 V conditioned signal that pairs naturally with industrial-grade A/D front-ends scaled to a 5 V reference. The differential measurement rejects common-mode disturbances common on long cable runs near motor drives and switching contactors. Apply a 0.1 uF decoupling capacitor and protective TVS clamps at the connector to handle ESD and inductive transients in cabinet installations.
おすすめ
Barometric Reference for Altimetry
Although primarily differential, the MPX5010D can be wired with the low-pressure port sealed against a known reference and the high-pressure port exposed, turning it into a high-accuracy barometric altimeter with 10 kPa headroom. ADC sampling at 1 Hz and software low-pass filtering yields altitude readings comparable to low-end altimeter modules and GPS augmentation. Use a sealed reference chamber to keep the differential baseline stable against environmental drift.
おすすめ
Appliance Water-Level Feedback
Washing machines, dishwashers and coffee appliances exploit the MPX5010D's 0 to 10 kPa range to detect water-column height without dipping any electronics into the fluid, simply by routing an air tube to the bottom of the sump. The conditioned 0 to 4.7 V signal feeds the appliance MCU directly, replacing legacy mechanical float switches with a quiet, reliable solid-state sensor. Add a water trap and lint guard at the air-tube pickup because the sensor's port is sized for clean air only.

設計ノート
The MPX5010D is ratiometric - its output scales with supply - so power it from the same clean 5 V rail that supplies the ADC reference to retain absolute pressure accuracy across the 0.2 V to 4.7 V output span. Place a 0.1 uF ceramic bypass capacitor within a few millimeters of the VCC pin to suppress digital switching noise; the part draws only a few milliamps so no bulk capacitor is needed, but the supply must stay within 4.75 V to 5.25 V to keep the calibration intact.
Avoid exposing the silicon diaphragm directly to liquid, dust or corrosive media because the sensing element is exposed through the port. Use a compatible media-isolating diaphragm or hydrophobic filter at the pneumatic pickup point. Leaving pins 4-6 floating is correct - they tie to factory trim networks and must not be grounded externally; ignoring this can disturb the calibrated transfer function.
Route the analog output (pin 3) away from switching converter inductors and high-current traces to prevent switching-noise coupling into the ADC input. A small RC low-pass on the output (10 kHz typical) is usually sufficient because the sensor bandwidth is intrinsically limited; higher software oversampling can be used to further improve effective resolution on top of any low-pass filter.
コンプライアンス情報
RoHS, lead-free and REACH status should be verified against the current NXP product page or certificate of conformance because the part has been manufactured across Motorola, Freescale and NXP ownership transitions. The MPX5010D is not AEC-Q100 qualified; consult the automotive MP3V5010 / MPXV5010 line for vehicle applications.
