MPX2053GVP - 50kPa Gauge Pressure Sensor, 4-SIP | NXP
MPN： MPX2053GVP ✓ 啟用中MPX2053GVP 概覽
A piezoresistive pressure sensor is a MEMS device in which a silicon diaphragm with embedded Wheatstone bridge resistors deflects under applied pressure, converting mechanical force into a differential millivolt output proportional to pressure. Pressure sensors sit within the broader transducer hierarchy as part of the sensor signal chain, downstream of physical phenomena and upstream of analog front-end (AFE) or ADC stages in measurement and control systems.
Key features include on-chip temperature compensation over the -40 C to +125 C range, calibrated span and offset for drop-in use, a 0 mV to 40 mV full-scale output at 10 V supply, and a vented gauge reference that measures pressure relative to ambient through the rear of the package. The Wheatstone bridge topology provides good linearity and low noise when excited from a stable low-impedance source.
Typical applications include HVAC blower and duct pressure monitoring, medical respiratory and ventilator equipment, industrial process control, altitude and barometric sensing, and appliance water-level detection. The vented gauge port design eliminates the need for external barometric correction in differential applications.
When designing with this device, decouple the supply with a 100 nF ceramic capacitor close to the supply pin and drive the bridge from a low-noise, low-impedance reference to minimize self-heating and span drift. Use a high-resolution ADC with at least 12 bits to resolve the 40 mV full-scale span.

典型應用
MPX2053GVP 適用於 6 應用s: HVAC Duct Static Pressure Monitoring, Medical Respiratory and Ventilator Pressure Sensing, Industrial Process Control and Flow Measurement, Barometric and Altitude Sensing, Appliance Water Level and Pump Pressure Detection, Pneumatic System Pressure Monitoring.
HVAC Duct Static Pressure Monitoring
The MPX2053GVP suits HVAC duct static pressure sensing in the 0 to 1 inch water column range (approximately 0 to 250 Pa), well inside its 0 to 50 kPa full-scale capability. The vented gauge port automatically cancels barometric drift, so the sensor reports true differential pressure across fans and filters without external compensation. Plumb the 4.93 mm tube inlet to the duct tap and excite the bridge from a regulated 10 V supply; the linear 40 mV span feeds directly into a 16-bit delta-sigma ADC for ±0.1 Pa resolution.
推薦
Medical Respiratory and Ventilator Pressure Sensing
The MPX2053GVP's on-chip temperature compensation from -40 C to +125 C and calibrated 0 to 40 mV span support medical respiratory equipment where airway pressure must be measured reliably across body-temperature variations. The 50 kPa range comfortably covers inspiratory and expiratory pressures in ventilator circuits, while the small SIP package fits compact handheld designs. Use an isolated ADC front end and a low-leakage tubing interface to meet IEC 60601 patient-safety requirements for medical electrical equipment.
推薦
Industrial Process Control and Flow Measurement
The MPX2053GVP is well-matched to industrial flow measurement across orifice plates, venturi tubes, and Pitot-static probes where differential pressure correlates with flow rate. The vented gauge port eliminates atmospheric drift when measuring line pressure, while the calibrated span simplifies PLC integration. The robust 4-SIP package and -40 C to +125 C rating support harsh factory environments, and the mV output interfaces directly with industrial 4-20 mA transmitters after amplification by an instrumentation amplifier.
推薦
Barometric and Altitude Sensing
The MPX2053GVP's 0 to 50 kPa span encompasses the entire barometric pressure range at sea level and high altitude, making it viable for weather stations, drone altitude hold, and avionics research. The vented gauge reference ensures the output always reflects pressure relative to local ambient, so altitude is derived from absolute pressure with a single calibration. Pair with a 24-bit ADC and temperature compensation algorithm to resolve altitude changes below 1 meter at standard atmospheric conditions.
推薦
Appliance Water Level and Pump Pressure Detection
The MPX2053GVP detects water column height in appliances such as dishwashers, washing machines, and water softeners by sensing hydrostatic pressure at the bottom of a tank or standpipe. The 0 to 50 kPa range covers approximately 0 to 5 meters of water, sufficient for most residential and light-commercial appliance tanks. The through-hole SIP package mounts easily on a control-board PCB near the pressure tap, and the mV output drives a comparator or ADC for level control.
推薦
Pneumatic System Pressure Monitoring
The MPX2053GVP monitors pressure in shop-air and pneumatic automation lines up to 50 kPa (about 7 PSI), sufficient for low-pressure control circuits and vacuum-blow-off systems. The linear output simplifies calibration against a reference gauge, and the SIP package integrates directly onto a manifold-mounted controller board. Drive the bridge from a regulated 10 V to 16 V rail and use an instrumentation amplifier with sufficient CMRR to reject ground noise from relay-driven solenoid valves.

設計說明
Drive the MPX2053GVP bridge from a low-noise, low-impedance 10 V excitation source such as the MAX6126 reference followed by a buffer op-amp. Add a 100 nF ceramic decoupling capacitor close to pin 4 (Vs) and a 100 nF cap on pin 2 (GND) to suppress high-frequency noise. Self-heating of the bridge at high excitation currents introduces span drift; keep total bridge drive below 1 mA to minimize thermal errors.
Place the sensor as close as possible to the ADC input to minimize noise pickup on the high-impedance mV output traces. Use guard rings around the output traces and a star-ground topology that ties the sensor GND, ADC GND, and excitation ground at a single point. Keep digital switching traces (PWM, relays) routed away from the bridge output to avoid coupling interference into the 40 mV full-scale signal.
The MPX2053GVP's 40 mV full-scale output is small relative to typical thermocouple and ground-loop noise, so use a chopper-stabilized or auto-zero instrumentation amplifier (such as the MAX4194 or MAX4209) with at least 100 dB CMRR at 50/60 Hz. Apply low-pass filtering at 1 kHz to limit noise bandwidth, and consider correlated double sampling in software to remove 1/f noise from the ADC conversion.
