Thermal Differential Pressure Transmitter – Overview

The Thermal Differential Pressure Transmitter is designed on the MEMS hot wire anemometer design. This combines with the integrated circuit to convert data into a differential pressure signal. It has very good zero point stability and small differential pressure detection capability.  It also boasts a high-pressure resistance.

Thermal Differential Pressure Transmitter – Features

  • Modbus RTU protocol
  • Physical switch : mmWS / inH2O / mmHg / mbar / Pa / hPa / kPa / mmH2O
  • Square root function
  • Option RS-485 communication interface
