MPX5010DP 概要
A piezoresistive pressure transducer is a solid-state sensor that converts applied gas or air pressure into a strain-induced change in resistance, which is then conditioned on-chip into a ratiometric analog output voltage proportional to pressure. The MPX5010DP belongs to the MPxx5010 family of monolithic silicon pressure sensors, situated in the broader hierarchy: pressure sensor -> MEMS sensor -> transducer -> sensor IC -> semiconductor. It is intended for systems employing a microcontroller or microprocessor with an A/D converter, where it replaces discrete bridge amplifiers and trimming circuits with a single calibrated device.
Key specifications include a full-scale span of 10 kPa, a sensitivity of 450 mV/kPa typical, an output range of 0.2 V to 4.7 V at 5 V supply, and a 5 V typical supply voltage (4.75 V to 5.25 V). The integrated bipolar signal chain delivers better than +/-1.5% linearity over the compensated temperature range of 0 to 85 C, while factory calibration removes the need for external passive trim networks. The dual-port (DP) mechanical configuration supports differential measurement between two air or non-corrosive gas sources.
Architecturally, the device combines a micromachined silicon diaphragm with thin-film metallization and bipolar signal processing on a single die. This monolithic integration is what enables its calibrated, temperature-compensated output without external components. The 6-SIP package provides two axial ports for differential pressure connection and four through-hole leads for power, ground, and analog output, simplifying PCB assembly.
Typical applications include HVAC variable-air-volume controllers, medical respiratory and CPAP monitors, industrial process control, water-level / liquid-level sensing via trapped air columns, altitude and barometric measurement, and consumer appliance pressure feedback. The differential topology is particularly suited to measuring pressure drop across filters, ducts, orifices, and small fans.
When designing with the MPX5010DP, decouple the supply with a 100 nF ceramic capacitor placed within 5 mm of the VCC pin and provide a stable 5 V rail, since the output is ratiometric. Keep both pressure ports free of moisture, particulates, and corrosive media; for liquid sensing, isolate the sensor via an air column or use the MPVZ5010 family with media-resistant gel.

主な用途
MPX5010DP の用途: 7 件s: HVAC Variable Air Volume (VAV) Control, Medical Respiratory / CPAP Monitoring, Filter / Orifice Pressure Monitoring, Water Level Sensing via Air Column, Industrial Process Air Flow Measurement, Barometric / Altitude Estimation, Small Fan / Blower Health Monitoring.
HVAC Variable Air Volume (VAV) Control
The MPX5010DP is well suited to HVAC VAV box control because its 0-10 kPa differential range matches the typical static pressure setpoint of duct-mounted flow sensors, and its 450 mV/kPa sensitivity provides 4.5 V of useful span on a 5 V rail - enough to resolve airflow setpoint changes of better than 0.05 kPa after a 10-bit ADC. Placed across a Pitot tube or orifice plate, the differential reading feeds a microcontroller that modulates a damper actuator. Unlike gauge-only sensors, the DP topology compensates for ambient barometric drift in rooftop installations.
おすすめ
Medical Respiratory / CPAP Monitoring
For CPAP machines and respiratory flow circuits, the MPX5010DP's differential topology allows direct measurement of pressure drop across a flow restriction or patient circuit, with the 0.2-4.7 V analog output simplifying interface to a medical-grade MCU ADC. The 450 mV/kPa sensitivity yields ~0.05 kPa resolution at 10-bit ADC - adequate for tracking breath-by-breath pressure waveforms above 1 kPa. Integrated temperature compensation from 0 to 85 C covers clinical-room environments without external linearization. The non-corrosive gas media rating is appropriate for breathing circuits.
おすすめ
Filter / Orifice Pressure Monitoring
The MPX5010DP excels at filter-loading and orifice-plate monitoring because the differential measurement intrinsically cancels ambient barometric pressure. As a filter loads with particulates, the pressure drop across it rises from ~0 kPa (clean) toward 10 kPa (clogged) - the 0.2-4.7 V output feeds a microcontroller that triggers a replacement alert. The 5 V ratiometric output lets the reading track the ADC reference, eliminating absolute calibration drift. The 4.93 mm ports accept common flexible tubing used in HVAC and pneumatic systems.
おすすめ
Water Level Sensing via Air Column
By submerging one port of the MPX5010DP at the bottom of a vented tube and leaving the other port open to atmosphere, the sensor measures the hydrostatic head of water trapped in the air column - converting liquid level into differential pressure. A 10 kPa range corresponds to about 1 meter of water column, sufficient for residential sump, tank, and pool level monitoring. The dual-port design intrinsically cancels atmospheric pressure variation, and the ratiometric 5 V output can be read by a battery-powered MCU with a stable LDO reference.
おすすめ
Industrial Process Air Flow Measurement
For compressed-air flow metering and pneumatic control loops, the MPX5010DP provides a factory-calibrated differential pressure signal that directly correlates with flow rate through a Venturi or laminar flow element. The 0-10 kPa range covers typical shop-air pressure drops (1-5 kPa), and the 5 V supply is readily derived from industrial 24 V via a small DC-DC converter. The 6-SIP package is robust to industrial vibration, and the integrated temperature compensation removes the warm-up drift that plagues discrete bridge amplifiers.
おすすめ
Barometric / Altitude Estimation
Although primarily a differential sensor, the MPX5010DP can be used for low-altitude barometric trends by referencing one port to a sealed vacuum capsule and the other to atmosphere - effectively converting it to an absolute barometer with 0-10 kPa range (roughly sea level to 20,000 ft). The 450 mV/kPa sensitivity gives ~0.01 kPa resolution at 10-bit ADC, corresponding to about 1 meter of altitude. For higher-altitude barometric applications, the dedicated BMP280 absolute-pressure I2C sensor is the preferred choice - the MPX5010DP is best reserved for differential topologies.
おすすめ
Small Fan / Blower Health Monitoring
By sensing the pressure rise across a small DC fan or blower, the MPX5010DP enables real-time airflow health monitoring - useful for server, embedded, and appliance fans where bearing wear manifests as a drop in static pressure. The 0.2-4.7 V analog output is read by the host MCU's ADC and trended over time; a falling baseline indicates degrading fan performance before failure. The differential topology rejects ambient barometric drift, and the 6-SIP package fits inside compact fan housings. Operating current is in the single-digit mA range, compatible with always-on monitoring.

設計ノート
The MPX5010DP output is ratiometric to VCC, so any noise or drift on the 5 V supply directly couples into the measurement. Place a 100 nF ceramic decoupling capacitor within 5 mm of pin 1 (VCC), and derive VCC from a low-noise LDO rather than directly from a switching regulator. For ADC readings, use VCC as the ADC reference so supply noise cancels out. Estimated supply current is in the single-digit mA range per datasheet typical conditions; a 50 mA LDO provides comfortable margin.
Route the analog output (pin 2) away from switching nodes, inductor coils, and high-current traces to minimize coupled noise. Keep both pressure ports mechanically isolated from the PCB to avoid stress on the sensor body, and use flexible silicone tubing (typically 4.93 mm / 3/16 in ID) with barbed fittings. Do not over-torque fittings - the SIP body is plastic and the internal port can crack above ~2 N·m.
Do not expose the ports to liquids, corrosive gases, or particulates - the die is bare silicon. For water or humidity exposure, route the medium through an air column or substitute the MPVZ5010 family with media-resistant gel. Do not apply pressure above the calibrated 10 kPa full scale without confirming the overload specification - permanent zero-shift can occur. Do not connect either port to a sealed volume during power-up; trapped pressure at 5 V supply application can produce transient over-range outputs.
The MPX5010DP output is a low-impedance analog voltage but the source impedance and capacitive load behavior is not formally specified; add a small RC filter (10 ohm + 100 nF) at the output if driving long cables or noisy ADC inputs. For ADC sampling, allow at least 1 ms settling time after multiplexer switching - the on-chip buffer has finite slew rate. Avoid driving the output into capacitive loads above 1 nF without a series resistor.
