MPXV5100DP - 100kPa Differential Pressure Sensor, 5V, 8-SOP | NXP
MPN： MPXV5100DP ✓ 啟用中MPXV5100DP 概覽
A piezoresistive pressure sensor is a device that converts applied mechanical pressure into a proportional change in electrical resistance, which is then linearized and amplified by on-chip circuitry into an analog output voltage directly readable by an MCU ADC. In the broader sensor taxonomy, this part is a board-mount pressure transducer -> MEMS sensor -> pressure sensor -> physical sensor. The MPXV5100DP integrates the mechanical diaphragm, Wheatstone bridge, temperature compensation, gain stage, and calibration on a single die, eliminating the need for external compensation networks.
Key features include 5% maximum pressure accuracy (typically better over 0 to 85 C), 45 mV/kPa nominal output span, Ratiometric analog output proportional to supply voltage, dual horizontal ports for differential sensing, and on-chip temperature compensation. The dual-port package allows easy pneumatic connection with flexible tubing on both sides of the sensor die.
The device uses advanced thin-film metallization and bipolar semiconductor processing to combine a single-element piezoresistive transducer with bipolar signal conditioning. The ratiometric output architecture means the output scales linearly with VCC, enabling direct ADC readings without precision reference voltage requirements.
Typical applications include HVAC airflow and differential pressure monitoring, medical respiratory equipment, process control and pump monitoring, altitude and barometric estimation, and industrial pneumatic feedback. The dual-port configuration makes it especially well suited to measuring pressure drop across filters, ducts, orifices, and flow elements.
When designing with this sensor, ensure the supply is well-decoupled with a 0.1 uF ceramic capacitor placed close to VCC and GND. Avoid exposing the ports to moisture, dust, or corrosive gases; the device is specified for clean dry air or non-corrosive gases only.

典型應用
MPXV5100DP 適用於 6 應用s: HVAC Differential Pressure Sensing, Medical Respiratory Equipment, Pump and Compressor Monitoring, Barometric and Altitude Estimation, Process Control and Industrial Automation, Flow Element Pressure Drop Measurement.
HVAC Differential Pressure Sensing
The MPXV5100DP is ideal for HVAC duct and filter pressure-drop sensing, where 0-to-100 kPa covers typical fan, blower, and VAV box static pressures. Its dual horizontal ports simplify inline plumbing on either side of a fan or filter, while the 0.2 V to 4.7 V ratiometric output connects directly to a 5 V MCU ADC without external conditioning. The on-chip temperature compensation keeps accuracy within +/-5% across typical building temperature swings, an advantage over discrete bridge sensors that need external RTD compensation. Same-side dual ports also reduce tubing routing complexity in tight HVAC equipment enclosures.
推薦
Medical Respiratory Equipment
The MPXV5100DP suits CPAP, ventilator, and anesthesia machine pressure monitoring where 0-to-100 kPa covers inspiratory and expiratory circuit pressures. Its differential measurement isolates patient-circuit pressure from ambient, an essential safety feature. The 5 V ratiometric 0.2 V to 4.7 V output interfaces cleanly with medical MCU ADCs and the on-chip signal conditioning reduces BOM and board area. The 8-BSOP dual-port package also permits sterile filter placement between patient and sensor, important in clinical respiratory hardware. Always validate per applicable medical device standards before use in patient-connected applications.
推薦
Pump and Compressor Monitoring
The MPXV5100DP fits pump inlet/outlet differential pressure monitoring where 0 to 100 kPa covers typical industrial pump head pressures. Its dual-port architecture allows differential measurement across pump elements to detect clogged filters, worn seals, or impeller degradation. The ratiometric 0.2 V to 4.7 V output interfaces with industrial PLC and MCU ADC inputs without precision references. On-chip temperature compensation supports industrial ambient ranges, and the 8-BSOP surface-mount package reflows directly onto pump-controller PCBs. Monitor trend data over time to detect pump performance degradation early.
推薦
Barometric and Altitude Estimation
The MPXV5100DP can serve barometric and altitude estimation when used in a sealed gauge configuration with a sealed reference port. Its 0 to 100 kPa range covers sea level through reduced-pressure altitudes, and the 45 mV/kPa nominal sensitivity at 5 V provides reasonable altitude resolution through the troposphere. The ratiometric output scales with VCC, so an ADC reference tied to the same rail preserves absolute accuracy as supply varies. The integrated temperature compensation minimizes altitude drift across typical environmental changes. Use a digital barometric helper may be added for higher-precision altimetry if required.
推薦
Process Control and Industrial Automation
The MPXV5100DP suits process control panels and industrial automation where 0 to 100 kPa covers typical pneumatic and hydraulic circuit pressures. Its differential measurement isolates process pressure from atmospheric variation, an advantage for closed-loop feedback control. The 5 V supply and 0.2 V to 4.7 V analog interface match industrial PLC analog input modules and embedded controller ADC channels. The 8-BSOP surface-mount package supports reflow soldering and high-density industrial PCB layouts. Long-term stability and on-chip compensation minimize periodic recalibration needs.
推薦
Flow Element Pressure Drop Measurement
The MPXV5100DP measures pressure drop across flow elements such as orifice plates, Venturi tubes, and laminar flow elements where 0 to 100 kPa covers many industrial gas and air flow applications. Differential measurement captures both upstream and downstream pressures simultaneously, an essential requirement for differential flow calculation. The dual-port 8-BSOP package simplifies mounting on flow-rig PCBs and the ratiometric analog output interfaces cleanly with flow controller MCUs. The on-chip signal conditioning removes the need for instrumentation amplifiers or external references.

主要差異化特點
- Highest-range variant in MPXV5100 family (對比MPXV5050DP)
- Differential dual-port same-side geometry (對比MPXV5100GP)
- 5 V supply ratiometric output (對比MP3V5010DP)
設計說明
Decouple VCC with a 0.1 uF ceramic capacitor placed as close as possible to the supply pins (1 and 2) and GND (pin 4). The ratiometric output scales with VCC, so an MCU ADC reference tied to the same 5 V rail preserves absolute-pressure accuracy. For best noise performance, add a small RC filter on the VOUT pin if long PCB traces connect the sensor to the ADC input.
Mount the dual-port package with both 3.3 mm tube ports facing the same side and away from vibration sources. Seal the reference port with clean dry air when used in gauge configuration; do not expose the ports to moisture, dust, or corrosive gases. Keep the sensor away from heat-generating components since on-chip temperature compensation has finite accuracy beyond 0 to 85 C.
Do not apply pressure exceeding the maximum overload specification or expose the die to liquids with pressure exceeding vacuum limits. The differential measurement is referenced to the second port; both ports must be connected to valid pressure sources or sealed. Verify port orientation matches the application reference on the datasheet before final assembly.
