MPXV2053GP 概要
A pressure sensor is a transducer that converts an applied physical pressure into a proportional electrical signal, used wherever a system must monitor or react to fluid or gas pressure. Within the broader taxonomy, the MPXV2053GP belongs to the sensor family, more specifically to piezoresistive (silicon strain-gauge) pressure sensors, and within that to the mV-output (uncompensated or partially compensated) subclass that requires an external signal-conditioning chain. Its on-chip temperature compensation and calibration distinguish it from bare die-strain elements, eliminating the need for external compensation circuits in many low-precision applications.
Key features of the MPXV2053GP include factory calibration, on-chip temperature compensation over 0°C to +85°C, excellent linearity across the 0–50 kPa range, and very low hysteresis. The sensor uses a single axial port with a tube interface, allowing direct pneumatic connection to the manifold under test. The 8-SMD form factor supports automated assembly, and the top-side port orientation simplifies manifold design in vertical-mount pressure assemblies. Output is ratiometric to supply voltage, meaning a 5 V supply halves the full-scale output to about 20 mV.
Typical applications include HVAC differential pressure sensing, medical inhalation and respiratory monitoring equipment, industrial process control and level measurement, altimeters and barometric instruments, and pneumatic control in fuel-cell and analytical instruments. The 50 kPa full-scale range is well suited to low-pressure gas and dry-air measurements where differential pressures span a few kPa up to nearly 1 atm of gauge pressure.
When designing with this part, plan for a low-noise, high-gain instrumentation amplifier (such as an INA125 or AD620 with gain of about 100) because the native 40 mV full-scale output is too small for direct ADC digitization in 12-bit systems. Provide adequate PCB isolation between the digital ground and the analog ground star-point near the sensor’s ground pins to avoid corrupting the small millivolt signal.

主な用途
MPXV2053GP の用途: 6 件s: HVAC Differential Pressure Sensing, Medical Inhalation and Respiratory Monitoring, Altimeters and Barometric Instruments, Industrial Process Control and Level Sensing, Pneumatic Control in Fuel-Cell and Analytical Instruments, Vortex and Flow Metering Systems.
HVAC Differential Pressure Sensing
The MPXV2053GP’s 0–50 kPa range covers the typical differential pressures measured across HVAC filters, fans, and variable-air-volume boxes. Its on-chip temperature compensation keeps the millivolt output stable across the 0–85°C air-handler operating envelope, eliminating the need for external thermistor networks. The vented-gauge port references ambient barometric pressure, so readings track true duct pressure rather than absolute pressure — ideal for filter-loading alarms. Outputs feed a low-noise instrumentation amp (e.g. INA125) with gain ≈100 to bring the 40 mV full-scale up to ADC range. Because the part is obsolete, plan inventory or move to the XGZP193 for new builds.
おすすめ
Medical Inhalation and Respiratory Monitoring
Respiratory instruments require accurate low-pressure gas measurement between -5 kPa and +50 kPa, well within the MPXV2053GP’s range. The small 0.13" tube port fits standard medical pneumatic fittings, simplifying hose interface design. The piezoresistive silicon diaphragm responds quickly to breathing-cycle pressure changes, and on-chip temperature compensation maintains accuracy over the 15–35°C clinical operating window. The millivolt-level output demands a high-CMRR amplifier such as AD620 to reject 50/60 Hz mains pickup on long patient cables. Note that for new medical designs the obsolescence of the MPXV2053GP drives engineering toward the XGZP193 or modern NXP families.
おすすめ
Altimeters and Barometric Instruments
Atmospheric pressure at sea level is about 101 kPa with a 1 kPa change roughly every 100 m of altitude, so the MPXV2053GP’s 50 kPa range captures meaningful altitude changes in handheld and weather-station altimeters when calibrated against a known reference. The vented-gauge configuration directly references atmospheric pressure through the port, avoiding absolute-pressure drift over time. Calibration routines stored in the host microcontroller map mV readings to elevation via the standard atmosphere model. The 8-SMD surface-mount package supports compact PCB layouts for handheld and wearable enclosures. For new designs the obsolescence of the MPXV2053GP directs engineers to pin-compatible XGZP193 or MPX2053 family variants.
おすすめ
Industrial Process Control and Level Sensing
Tank-level sensing via hydrostatic head pressure produces signals in the low kilopascal range when measuring water columns of a few hundred millimeters — squarely within the MPXV2053GP’s 0–50 kPa envelope. Pneumatic control loops in analytical instruments also operate in this pressure band. The on-chip calibration compensates the millivolt output for the thermal gradients found in industrial enclosures, and the small SMD package fits inside compact process transmitters. Designers pair the sensor with a current-loop (4–20 mA) transmitter IC such as XTR105 to deliver industrial-standard analog signals to PLCs. Since the MPXV2053GP is EOL, both retrofit (existing designs) and forward-looking builds should evaluate the XGZP193 or NXP MPX family updates.
おすすめ
Pneumatic Control in Fuel-Cell and Analytical Instruments
Analytical instruments such as gas chromatographs and fuel-cell test stations need precise low-pressure gas monitoring around 0–50 kPa for flow control and leak detection. The MPXV2053GP’s vented-gauge configuration isolates the sensor from absolute atmospheric drift while still registering small differential pressures in the gas line. The millivolt output interfaces cleanly with a precision 24-bit ADC, and on-chip temperature compensation reduces the thermal drift typically encountered in heated analyzer enclosures. Engineers use the sensor to detect blockage in fuel-cell hydrogen lines where a pressure rise indicates flow restriction. Pair it with an instrumentation amp and a sealed NXP MPX pressure sensor at a higher range for differential measurement.
おすすめ
Vortex and Flow Metering Systems
Industrial flow meters detect pressure pulses generated by vortex shedding behind a bluff body in the flow stream; the resulting differential pressure signal lies in the 0–50 kPa band that the MPXV2053GP measures directly. The piezoresistive element’s high sensitivity resolves small pressure pulses even at low flow rates, and the small tube port adapts to standard process-piping adapters. Instrument designers follow the sensor with a low-pass filter and high-gain instrumentation amp to extract the vortex frequency (proportional to flow velocity). Always plumb the high-pressure side to the sensor port and the low-pressure side to the vent port for proper vented-gauge operation.

設計ノート
Estimated: with a native output of 40 mV at 10 V, you need an instrumentation amplifier with gain of about 100 to bring the signal up to ~4 V full-scale for a 12-bit ADC at 5 V. Choose a low-noise amp with at least 100 dB CMRR (e.g. INA125, AD620). Place the amp within a few centimeters of the sensor to keep the high-impedance millivolt lines short, and use a Kelvin connection from the sensor GND to the amp’s REF pin to avoid ground loops.
Route the high-impedance mV signal traces on a separate analog ground island that joins the system ground at a single star-point near the sensor. Keep digital and switching-converter traces away from the sensor bond area. The vent hole beside the tube port must remain unobstructed — do not place components within 3 mm of the vent or seal the vent with conformal coating. Use a sealed 8-SMD land pattern with sufficient copper pour under the thermal-pad area for mechanical stability.
Estimated: despite on-chip temperature compensation over 0–85°C, the sensor still exhibits residual TCO and TCS errors in the datasheet; if the application operates near the temperature extremes, perform a two-point calibration (zero at minimum temperature, span at nominal) at the system level. Mount the sensor away from heat sources such as power inductors and MOSFETs because the silicon die is small and tracks local PCB temperature quickly.
