MPX2010DP Обзор
A piezoresistive pressure sensor is a solid-state transducer whose Wheatstone-bridge strain gauges diffused into a silicon diaphragm convert mechanical strain into a proportional millivolt-level voltage output. Within the broader transducer taxonomy, this device sits at: piezoresistive sensor -> MEMS pressure sensor -> pressure transducer -> sensor. The on-chip thin-film resistor network delivers a temperature-compensated, calibrated output that simplifies the signal-chain by removing the need for external compensation circuitry in many designs.
Key features include 0 to 10 kPa (0 to 1.45 PSI) differential pressure range, 25 mV typical full-scale span at 10 V supply, ±0.05% linearity, ±0.1% to ±2.5% temperature compensation across 0 to 85 °C, and a fast 1.0 ms response time. The 4-SIP through-hole package aligns the dual pressure ports along the sensor axis and supports pressures applied via flexible tubing up to 75 kPa maximum overpressure and 200 kPa burst pressure. According to the NXP product overview, the device operates from -40 °C to +125 °C, making it suitable for industrial and consumer environments.
Typical applications include HVAC air-flow monitoring, medical respirators and ventilators, barometric altimeters, industrial process control loops, level detection in sealed containers, and water-column altitude measurement. The dual-port differential topology allows reference-pressure measurement, eliminating barometric drift in measurements where gauge pressure is converted to absolute flow.
When designing with the MPX2010DP, place the device in a region of stable ambient temperature and isolate the ports from condensation; use a differential amplifier (e.g., INA125 or equivalent instrumentation amp) to bring the 25 mV span up to ADC-friendly levels. Bridging the result with a low-offset, low-noise op-amp preserves the calibrated linearity across the full temperature range.
The MPX2010, MPXV2010G and MPXM2010 series provide accurate and linear output proportional to applied pressure, ideal for OEM system designs. This page synthesizes distributor pricing, drop-in alternatives, and practical design guidance that extends beyond the manufacturer datasheet.

Типичное применение
MPX2010DP подходит для 6 применениеs: HVAC Duct Airflow Monitoring, Medical Respirator / Ventilator Pressure Sensing, Barometric Altimeter / Handheld Altitude Measurement, Industrial Process Control / Filter Monitoring, Sealed-Container Liquid Level / Bubble Detection, Water-Column Altitude / HVAC Manometer.
HVAC Duct Airflow Monitoring
The MPX2010DP's 0 to 10 kPa differential range fits residential and light-commercial HVAC duct static-pressure monitoring, where typical operating pressures span 25 to 1000 Pa. The 25 mV full-scale span at 10 V excitation provides sufficient headroom for an instrumentation-amplifier front-end (e.g., INA125) to drive an ADC across 10-bit or 12-bit resolution. The MPX2010DP holds ±0.05% linearity at room temperature per the NXP datasheet, giving repeatable airflow measurements across multiple ducts. It is preferred over higher-range devices like the MPX2100DP because the lower full-scale yields approximately 10× better resolution in the airflow operating region.

Medical Respirator / Ventilator Pressure Sensing
The MPX2010DP is widely deployed in medical respirator inspiratory-line pressure monitoring because inspiratory pressures in CPAP and BiPAP machines fall within 0 to 10 kPa (0 to 1020 mmH2O). The device's on-chip temperature compensation from 0 to 85 °C matches standard clinical ambient conditions, and its 1.0 ms response time captures pressure transients associated with patient breathing cycles. Combined with a low-noise analog front-end, the MPX2010DP delivers reliable breath-detection signals while keeping per-unit cost low for OEM medical devices.

Barometric Altimeter / Handheld Altitude Measurement
For handheld altimeter and weather-station designs measuring altitude above sea level, 10 kPa of differential range corresponds to approximately ±830 meters relative to a known reference pressure. The MPX2010DP's small 25 mV span at 10 V lets a precision 16-24 bit ADC resolve altitude to better than 1 m after signal conditioning. Its -40 to +125 °C operating range and on-chip calibration over 0 to 85 °C fit outdoor recreational devices that may experience cold-storage and warm-skin conditions in a single use cycle.
Рекомендуется
Industrial Process Control / Filter Monitoring
In industrial filter-clog detection and process-line pressure monitoring, the MPX2010DP detects small differential pressures across filter elements where loading raises pressure drop from <0.5 kPa clean to several kPa dirty. Its 4-SIP dual-port package accepts differential tubing for true filter pressure-drop measurement independent of barometric drift. Per the NXP datasheet, the device holds ±0.05% linearity and survives 75 kPa overpressure without sensor damage, making it suited to industrial environments where supply-line transients occur.
Рекомендуется
Sealed-Container Liquid Level / Bubble Detection
In gas-purged closed vessels, the MPX2010DP can detect liquid-column height by sensing the head pressure of a trapped gas bubble above the liquid. The 10 kPa range covers water-column heads up to approximately 1 meter, sufficient for laboratory and small-tank level measurement. Its dual-port differential topology ignores barometric pressure variation, an advantage over single-port gauge-style sensors that suffer altitude-induced zero drift. Use a buffered op-amp such as the TLC2252 to drive the ADC from the sensor's small millivolt output.
Рекомендуется
Water-Column Altitude / HVAC Manometer
The MPX2010DP is well adapted to HVAC manometer and low-pressure water-column altitude measurement, where 10 kPa corresponds to 1020 mm H2O - encompassing residential building water-loop differentials. Its compact 4-SIP body and 0.19 inch axial tubes simplify plumbing integration, and its NXP factory calibration removes the need for end-product trim. Paired with a small microcontroller and an LCD, the device yields a handheld digital manometer at modest cost relative to commercial units.

Заметки по проектированию
The MPX2010DP outputs only 25 mV at 10 kPa full scale; route sensor outputs to an instrumentation amplifier with shielded twisted pairs or short tracks to avoid 50/60 Hz pickup. Place the INA125 within 50 mm of the sensor, use a guard trace between Vout+ and Vout-, and add 100 nF bypass at Vs. Estimated: at 50 mm track length and 5 cm² ground plane, ambient 50 Hz hum drops below 10 µVpp; otherwise output can be noise-limited at the 8-bit ADC level.
Do not exceed 75 kPa common-mode or differential overpressure, and never apply liquid directly to the ports - the die and housing are dry-gas-only. Also check calibration offset between lots: NXP/MPX2010 series historically carried a 0 mV nominal offset but later revisions may specify ±1.0 mV. Always perform a zero-pressure calibration at your operating temperature before full-scale calibration, and store the offset in firmware for accurate readings.
On-chip temperature compensation is calibrated over 0 to 85 °C; outside this band the device still operates up to +125 °C but uncorrected drift increases. Estimated: 1 °C temperature excursion away from the calibration point yields roughly 0.2% full-scale drift without software compensation. For applications with continuous exposure above 85 °C or below 0 °C, add an external temperature sensor and a one-temperature-point software trim.
Mount the 4-SIP tube port vertically or horizontally on the PCB with the tube headers aligned in the airflow direction. Use flexible silicone tubing (inner diameter 4.93 mm / 0.19 inch) for pressure input. Avoid mechanical stress on the SIP body - any flexure of the leads can shift calibration. Add a small adhesive strain-relief at the tube-to-port junction to isolate vibrations from the sensor.
