MPXV5050VC6T1 概述
What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a MEMS device in which four silicon piezoresistors arranged in a Wheatstone bridge on a diaphragm change resistance in proportion to applied strain. As pressure deflects the diaphragm, the bridge output is amplified and conditioned by on-chip circuitry to deliver a high-level, temperature-compensated analog voltage proportional to pressure, eliminating the external instrumentation amplifier and calibration steps normally required for bare bridge sensors.
The MPXV5050VC6T1 family is rated for a pressure range of 0 to -50 kPa (vacuum mode) with a sensitivity of 90 mV/kPa and a 5 V supply span. The integrated signal chain delivers 5% accuracy over 0°C to 85°C, on-chip temperature compensation, and a typical response time suitable for industrial, medical, and HVAC closed-loop control. The SOP-8 surface-mount form factor with top port and 0.13 inch (3.17 mm) tube port allows direct manifold mounting and high-volume pick-and-place assembly.
Typical applications include vacuum pump monitoring, HVAC airflow sensing, respirator and ventilator pressure feedback, barometric altitude estimation, and industrial process control where a conditioned 0.1 V to 4.6 V analog output can be read directly by an MCU ADC.
When designing with this part, decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin, and add a 1 µF bulk capacitor on the supply rail. Drive the analog output through an RC low-pass filter if the application samples at less than the sensor's response bandwidth to avoid aliasing.

典型应用
MPXV5050VC6T1 适用于 6 应用s: Vacuum Pump Monitoring, HVAC Airflow and Duct Pressure Sensing, Medical Ventilator and CPAP Pressure Feedback, Barometric Altitude Estimation, Industrial Process Control Loops, Appliance and White Goods Vacuum Sensing.
Vacuum Pump Monitoring
The MPXV5050VC6T1 is a natural fit for vacuum-pump closed-loop monitoring because its 0 to -50 kPa range spans the typical suction envelope of medical suction, vacuum-bag transfer, and pick-and-place vacuum generators. With 90 mV/kPa sensitivity and a ratiometric 0.1 V to 4.6 V output, the sensor delivers a directly ADC-readable voltage that scales with applied vacuum, removing the need for external instrumentation amplifiers or calibration tables. Designers wire VCC to a clean 5 V LDO rail and route the analog output through a 10 kHz low-pass RC filter to suppress pump-induced switching noise. Compared to a bare piezoresistive bridge, the integrated signal chain shrinks BOM and PCB area while preserving ±5% accuracy across 0 to 85°C, which is sufficient for pump health trending and leak detection in industrial automation.
推荐
HVAC Airflow and Duct Pressure Sensing
In HVAC variable-air-volume (VAV) boxes and duct static-pressure probes, the MPXV5050VC6T1 measures the small negative pressures (typically -0.1 to -1 kPa) that drive damper modulation. Its 90 mV/kPa sensitivity provides roughly 9 mV to 90 mV across the damper-control window, well within the resolution of a 12-bit ADC at 5 V full scale. The on-chip temperature compensation reduces drift across the 0 to 85°C HVAC envelope, and the top-port SOP-8 footprint mounts cleanly inside the actuator housing. Designers often pair it with a differential reference to cancel altitude-induced barometric shifts; for absolute barometric use the MPX4115 family is preferred instead.
推荐
Medical Ventilator and CPAP Pressure Feedback
The MPXV5050VC6T1 is widely used in ventilator, BiPAP, and CPAP machines for inspiratory-pressure feedback in the 0 to -50 kPa range. Its 5% accuracy and ratiometric 0.1 V to 4.6 V output translate directly to breath-by-breath pressure readings without external calibration, and the SOP-8 surface-mount form factor allows compact assembly inside the patient-circuit housing. Engineers typically add a 0.1 inch tube with a hydrophobic anti-bacterial filter between the patient circuit and the sensor port to prevent biofluid ingress. The on-chip signal chain keeps the BOM and cost low enough for high-volume disposable-circuit medical designs.
推荐
Barometric Altitude Estimation
For low-cost altitude estimation in drones, weather stations, and portable instruments, the MPXV5050VC6T1 can be paired with a complementary absolute-pressure sensor to compute altitude from differential pressure. While the device is optimized for vacuum measurement, its calibrated transfer function is linear enough for relative altitude trends. Designers should subtract the local barometric baseline at power-up to remove weather-induced drift. The 5 V ratiometric output interfaces directly to most MCU ADCs and the small SMD package suits weight-constrained drone applications.
推荐
Industrial Process Control Loops
In process-control applications such as tank-level sensing, leak detection, and vacuum-clamp force feedback, the MPXV5050VC6T1 delivers a calibrated analog voltage that interfaces directly with PLC analog-input modules. The 0 to -50 kPa range covers many vacuum-clamp and pick-and-place force-feedback needs, while the on-chip conditioning eliminates per-channel calibration on the factory floor. Mount the sensor close to the pressure port via short, rigid tubing to preserve bandwidth, and use the same regulated 5 V rail that powers the PLC analog front-end to keep the ratiometric reading accurate.
推荐
Appliance and White Goods Vacuum Sensing
Vacuum-cleaner suction control, robotic-mop water-flow sensing, and dishwasher drain monitoring all rely on small differential-pressure transducers in the 0 to -50 kPa window. The MPXV5050VC6T1 provides a conditioned analog output that the appliance MCU can sample directly to regulate motor speed or detect clogged filters. Its 8-SMD SOP-8 footprint reflows with standard lead-free profiles, and the on-chip calibration removes the need for in-line trimming, keeping per-unit assembly cost low in high-volume appliance manufacturing.

设计说明
Power the MPXV5050VC6T1 from a clean 5 V LDO rail rated for at least 10 mA. The output is ratiometric to VCC, so any ripple on VCC couples directly into the analog output as pressure-readout error. Place a 100 nF ceramic decoupling capacitor within 5 mm of the VCC pin and add a 1 µF bulk capacitor on the supply rail to suppress switching-converter ripple. For best absolute accuracy, drive both the sensor VCC and the MCU ADC reference from the same low-noise regulator.
Route the analog output trace away from switching-converter nodes, motor drivers, and high-current traces; use a ground guard ring around the sensor footprint to reduce common-mode noise pickup. Keep the tube port unobstructed and add a hydrophobic membrane in medical and outdoor applications to prevent fluid or dust ingress. Use rigid, short tubing between the pressure source and the port to preserve bandwidth and avoid mechanical resonances that couple into the diaphragm.
Add a 10 kHz RC low-pass filter (1 kΩ + 15 nF, or similar) on the analog output before the MCU ADC to suppress high-frequency motor and switching noise while preserving the closed-loop control bandwidth. The on-chip bandwidth is well above 10 kHz, so this filter does not materially slow pressure tracking. If sampling below 1 kHz, add additional software averaging or decimation to push the effective resolution beyond the raw 10-bit or 12-bit ADC count.
