Differential Pressure Transmitter  – Overview

This differential pressure transmitter is designed according to the MEMS hot wire anemometer technology.  This has very good zero point stability and small differential pressure detection capability, as well as high-pressure resistance. The transmitter, using the pressure difference, passes a very small amount of gas through the airflow channel of the sensor. Combined with the integrated circuit, it converts into a differential pressure signal.

Differential Pressure Transmitter  – Features

  • Low-pressure monitoring, high-pressure resistance
  • Silicon chips on differential pressure module of MEMS integration technology
  • RS-485 communication interface (Optional), Modbus RTU protocol
  • Physical unit switch (User Interface): mbar / mmWS / inH2O / mmHg/ Pa / hPa / kPa / mmH2O
  • Square root function
  • Offset function / UI software
