MPX2053DP - 50 kPa Differential Pressure Sensor | NXP | 4-SIP Module
MPN： MPX2053DP ✓ 啟用中MPX2053DP 概覽
A piezoresistive pressure sensor is a MEMS device whose Wheatstone-bridge strain gauges are diffused into a silicon diaphragm that flexes under applied pressure, producing a differential output voltage proportional to the pressure differential across its two ports. In the broader sensor hierarchy, the MPX2053DP sits within pressure sensors -> MEMS sensors -> transducers -> sensors, and is commonly interfaced to instrumentation amplifiers or ADC front ends. Temperature compensation and span/offset calibration are performed by laser-trimmed thin-film resistors on-chip, eliminating the need for external compensation networks in many applications.
The MPX2053DP features a typical full-scale span of 40 mV at 10 V supply, a maximum offset of ±1.0 mV, and a response time of 1.0 ms. The device operates from a single 10 V typical supply (maximum 16 V) and is specified over 0 °C to +85 °C. Ratiometric output means the span scales linearly with supply voltage, simplifying ADC interfacing. The dual-port SIP package (Case 344-15) accepts 4.93 mm (0.19 inch) tubing for pneumatic or hydraulic differential measurement.
Typical applications include medical instrumentation (respiratory monitors, ventilators, blood pressure monitors), HVAC airflow and filter monitoring, industrial process control, level detection, and barometric differential measurement. The 0.8 mV/kPa sensitivity makes the device well-suited for low-pressure biomedical and environmental sensing.
Designers should use a high-precision instrumentation amplifier (such as an INA126 or AD620) to boost the 40 mV full-scale output to a usable 0-5 V or 4-20 mA range. Add 100 nF supply decoupling close to the sensor pins and a resistive bridge-drive configuration if ratiometric ADC sampling is required.

典型應用
MPX2053DP 適用於 6 應用s: Medical Respiratory Flow Monitoring, HVAC Filter and Duct Pressure Monitoring, Industrial Process Control and Level Detection, Barometric and Altitude Measurement, Blood Pressure Monitor Front-End, Environmental Air Quality and Flow Sensing.
Medical Respiratory Flow Monitoring
The MPX2053DP's 0-50 kPa differential range and 0.8 mV/kPa sensitivity make it well suited for spirometry and respiratory monitoring where flow head is created by a pneumotachograph. In this role, the sensor measures the pressure drop across a flow restriction, which an external circuit converts to volumetric flow. Its 1 ms response time resolves individual breath cycles, and on-chip temperature compensation keeps readings stable across 0 °C to +85 °C ambient shifts in clinical and home-care equipment.
推薦
HVAC Filter and Duct Pressure Monitoring
Commercial HVAC systems use differential pressure sensors to monitor air filter loading and duct static pressure. The MPX2053DP's 7.25 PSI full-scale and 0-50 kPa range cover the typical 0.1-2.0 inch H2O pressure drops used for filter diagnostics, while its dual barbed ports accept standard 0.19 inch tubing for inline duct installation. Ratiometric output simplifies the ADC interface when driven from the same 10 V reference, eliminating supply-drift errors during long measurement campaigns.
推薦
Industrial Process Control and Level Detection
The MPX2053DP measures differential pressure in closed vessels, hydrostatic tank levels, and pipe flow via orifice plates. Its 50 kPa range covers most low-pressure industrial process loops below 7 PSI, and its 4-93 mm dual-port SIP accepts the standard pneumatic fittings found in process plants. The ratiometric 0-40 mV output is easily scaled by an isolated 4-20 mA transmitter front-end for plant-wide SCADA integration and certified regulators.
推薦
Barometric and Altitude Measurement
For portable weather stations and drone altimeters, the MPX2053DP can be configured as a sealed-gauge reference with one port capped to ambient, providing a low-cost barometric pressure measurement. Although designed primarily for differential sensing, the single-port reference technique yields useful readings up to 50 kPa above the sealed reference. Combined with a temperature sensor, the device enables altitude calculation for unmanned aerial vehicles and recreational GPS instruments.
推薦
Blood Pressure Monitor Front-End
The MPX2053DP is a long-established choice for electronic sphygmomanometers, where its 0-50 kPa range covers cuff pressures up to 300 mmHg. The 0.8 mV/kPa sensitivity yields sufficient resolution to resolve systolic and diastolic events when amplified by an instrumentation amplifier. On-chip temperature compensation and laser-trimmed calibration deliver accuracy suitable for consumer health devices and ambulatory blood pressure monitors used by patients at home.
推薦
Environmental Air Quality and Flow Sensing
Building automation and indoor air-quality systems use differential pressure sensors to detect airflow across ventilation grilles, fan operation, and cleanroom pressure cascades. The MPX2053DP's dual barbed ports accept standard pneumatic tubing for inline measurement, and its 1 ms response enables detection of rapid fan startups. Ratiometric output allows direct ADC sampling using the same reference that drives the sensor, simplifying the BOM and improving long-term stability.

設計說明
Estimated: The MPX2053DP differential output is 40 mV full-scale at 10 V supply, so a gain of ~100 is needed to drive a 5 V ADC. Use an instrumentation amplifier such as INA126 or AD620 with RG ≈ 1.2 kΩ for INA128 (gain = 1 + 49.4 kΩ/RG). Route the sensor outputs as a differential pair with equal-length traces and a ground guard trace to reject supply-coupled noise. Place a 100 nF ceramic bypass capacitor directly across pins 1 and 2 of the SIP module within 5 mm of the leads.
Do not expose the MPX2053DP die to liquids, oils, or corrosive gases - the silicon die is exposed at the port opening. For liquid pressure measurement, mount an inert fluid isolator (thin oil column behind a flexible diaphragm) between the media and the sensor. Also note that the device is not AEC-Q100 qualified - for automotive applications use the MPX5700AS or MPXx5010 family which carry automotive-grade certification.
The 4-SIP Case 344-15 package is through-hole and stands approximately 15 mm above the PCB. Reserve at least 20 mm of vertical clearance above the board for tubing connections. Provide strain-relief loops for the pneumatic tubing to avoid mechanical stress being transmitted to the sensor ports, and use flexible silicone or Tygon tubing rated for the application's pressure and chemical compatibility.
Self-heating of the bridge is negligible (<5 mW dissipation), so the device can be operated in still air without thermal concerns. However, for highest accuracy over the 0 °C to +85 °C range, mount the sensor away from heat sources such as power resistors, voltage regulators, and power inductors. The laser-trimmed temperature compensation is calibrated for the part's self-heating profile, so external heating may degrade accuracy.
