Description

The DPF differential pressure sensor module consists of a pressure sensor and signal processing circuit in a COB package, mounted on a square PCB substrate made of ceramic. It has the characteristics of small waveform coefficient and high reliability. The module uses the supply voltage as a reference to generate a calibrated and temperature-compensated voltage signal proportional to the input pressure. The working pressure range is gauge voltage-20~+80KPa, the supply voltage is 5±0.25V, and the typical current is 2.5 mA.

 

Features

  • Maximum error of 1% in the range of 0~85°C
  • Temperature compensation range -40~125°C
  • Small size
  • High reliability, low drift
