MPX2202D 概要
A pressure sensor is a transducer that converts an applied physical pressure into a reproducible electrical signal. The MPX2202D belongs to the piezoresistive sensor family, in which diffused silicon strain gauges form a Wheatstone bridge on a monolithic diaphragm. When pressure deflects the diaphragm, the gauges change resistance unbalancing the bridge and producing a pressure-proportional differential output. This category sits within MEMS sensors -> transducers -> signal conditioning chains in industrial and medical instrumentation.
Key specifications include a maximum operating pressure of 29.01 PSI (200 kPa), a supply voltage of 10 V to 16 V, and a typical Wheatstone bridge output of 0 mV to 40 mV at 10 V. On-chip temperature compensation keeps the span and offset stable over the operating range, eliminating the need for external analog trimming in many designs. The unibody 4-SIP package integrates the sensing die and port into a single molded housing for through-hole PCB mounting.
Architecturally, the MPX2202D uses a monolithic silicon die with a chemically etched diaphragm and four piezoresistors in a Wheatstone bridge arrangement. The on-chip compensation network nullifies temperature-induced span and offset shifts, which simplifies the downstream instrumentation amplifier stage. The result is a calibrated, ratiometric analog output that scales linearly with applied differential pressure across 0 to 200 kPa.
Typical applications include HVAC airflow and differential pressure monitoring, medical respiratory equipment such as spirometers and ventilators, process control instrumentation, altitude and barometric measurement, and industrial pneumatic system monitoring. The differential port style makes it well suited to measuring pressure drop across filters, valves, or HVAC duct restrictions.
When designing with the MPX2202D, ensure the instrumentation amplifier input common-mode range accommodates the sensor's bridge bias, and use a stable low-noise supply to avoid corrupting the millivolt-level output. Add protection against condensation and overpressure spikes to extend sensor life in humid or pulsating environments.

主な用途
MPX2202D の用途: 6 件s: HVAC Airflow and Filter Monitoring, Medical Respiratory Equipment, Process Control Instrumentation, Altitude and Barometric Measurement, Industrial Pneumatic System Monitoring, Automotive Sensor and Test Bench.
HVAC Airflow and Filter Monitoring
The MPX2202D's 200 kPa (29.01 PSI) differential range and millivolt-level Wheatstone bridge output make it well suited to measuring pressure drop across HVAC filters, coils, and duct restrictions. Placed inline with the duct using its 0.136 in female ports, the sensor produces a 0-40 mV signal proportional to filter loading; an instrumentation amp then drives the building management controller. The 1 ms response time captures transient airflow events, while the on-chip temperature compensation keeps the reading stable across varying return-air temperatures typical of commercial HVAC systems.
おすすめ
Medical Respiratory Equipment
The MPX2202D's differential port configuration and fast 1 ms response time fit respiratory monitoring in ventilators, CPAP machines, and spirometers. The sensor measures airway pressure drop across flow elements or directly senses lung-pressure differentials, producing a calibrated 0-40 mV output that scales linearly with airway pressure. The on-chip temperature compensation keeps readings stable across body-temperature inspired gas, while the unibody 4-SIP package allows easy integration into the patient-circuit manifold. Medical designs should verify the obsolete lifecycle status and consider the active MPXV2202G surface-mount variant for new certifications.
おすすめ
Process Control Instrumentation
The MPX2202D's 200 kPa range and ratiometric 0-40 mV output fit industrial process control loops monitoring liquid or gas differential pressures in pipes, tanks, and reactors. The 4-SIP unibody package mounts directly on a process-control backplane, and the millivolt output is digitized by an ADC referenced to the same 10 V supply for noise-immune ratiometric readings. The 10-16 V supply range aligns with industrial 12 V and 15 V control rails, simplifying power architecture. Its on-chip temperature compensation reduces recalibration cycles, and its 1 ms response handles most closed-loop process control bandwidths.
おすすめ
Altitude and Barometric Measurement
The MPX2202D's 200 kPa full-scale covers the full range of atmospheric pressure from sea level (101 kPa) to high-altitude operation, and its Wheatstone bridge output can be calibrated against a precision ADC to deliver altitude readings within +/-1 meter after compensation. In weather stations, drone altitude hold, and barometric altimeters, the sensor's differential port configuration allows sealing one side as a reference while the other samples ambient. The on-chip temperature compensation is critical for outdoor and airborne applications where ambient temperature swings affect both the bridge span and offset.
おすすめ
Industrial Pneumatic System Monitoring
The MPX2202D handles compressed-air differential pressure monitoring in pneumatic actuators, valves, and regulators operating below 200 kPa. The 0.136 in ports accept standard pneumatic fittings, and the 1 ms response captures regulator dynamics during valve switching. The ratiometric 0-40 mV output at 10 V supply can be scaled to match a 0-10 V industrial analog input by adding an instrumentation amp with 250x gain. Its unibody package withstands industrial vibration better than PCB-only sensors, and the obsolete lifecycle status should prompt evaluation of the MPXV2202G surface-mount upgrade for new deployments.
おすすめ
Automotive Sensor and Test Bench
The MPX2202D's differential measurement capability suits automotive test benches monitoring fuel pressure, oil pressure, and intake manifold differential pressure. The 4-SIP through-hole package allows easy installation on test fixtures, and the 10-16 V supply range matches automotive 12 V power rails. While the part is not AEC-Q100 qualified, its robust unibody construction and on-chip temperature compensation deliver reliable readings across engine-bay thermal conditions. For production automotive designs, select AEC-Q100 qualified NXP sensors from the MPX-series or migrate to the surface-mount MPXV2202G family.

設計ノート
The MPX2202D produces a millivolt-level (0-40 mV) bridge output that is highly susceptible to noise pickup. Use shielded twisted-pair cabling from the sensor to the instrumentation amplifier, keep the cable under 30 cm, and place the INA as close as possible to the sensor pins. Add 100 nF ceramic bypass capacitors on the Vs+ and GND pins at the package to suppress supply noise that would otherwise couple directly into the bridge output.
Do not apply pressure beyond the burst pressure rating or expose the ports to liquids without proper sealing - the MPX2202D's gel-coated die tolerates humid air but fails with direct water contact. Verify the common-mode voltage of your instrumentation amplifier can swing to the bridge mid-supply (around 5 V at 10 V supply); many low-voltage instrumentation amps cannot accommodate this range and will saturate, producing a flat output at high pressure.
Power the MPX2202D from a stable low-noise 10 V to 16 V supply shared with the ADC reference if possible, to exploit the ratiometric output and cancel supply drift. A 78L10 regulator with 100 nF + 10 uF decoupling is sufficient for most applications; for low-noise designs, add an LT3042 or similar ultra-low-noise LDO between the regulator and the sensor's Vs+ pin. Estimated: at 10 V supply and 1 mA bridge current, dissipation is 10 mW - thermal management is not a concern.
