Differential Pressure Breakout

Differential Pressure Breakout comprises NXP's MPXV5010DP, is an Integrated Silicon Pressure Sensor On-Chip Signal Conditioned, Temperature Compensated, and Calibrated. Differential Pressure Breakout consists of two axial ports to accommodate industrial grade tubing. In the temperature range between 0º and 85ºC, the maximum error rate of the sensor is 5.0%.

Features

  • MPXV5010DP has an analog output
  • Temperature Compensated over -40 to +125C
  • The signal passes through the onboard 22-bit ADC before being outputted through the SPI interface
  • Durable Epoxy Unibody and Thermoplastic (PPS) Surface Mount Package.

Specifications

  • Operating Voltage : 5V
  • Operating Pressure - 1.45 psi
  • Port Type - Dual Radial Barbed
  • Port Size - 4.93 mm
  • Interface- SPI / Analog Interface
  • Measurement range- 0 to 10 kPa
