Pressure Transmitters: Accurate and Reliable Pressure Measurement for Industrial Applications

Pressure transmitters are essential components in industrial automation and process control systems. Designed to accurately measure the pressure of gases or liquids and convert that data into an electrical signal, pressure transmitters ensure the safe, efficient, and consistent operation of critical systems across a wide range of industries—including oil & gas, water treatment, manufacturing, and HVAC.

What Is a Pressure Transmitter?

A pressure transmitter is an electronic device that senses pressure and transmits a proportional signal to a control or monitoring system. These transmitters are designed to handle various types of pressure—gauge, absolute, or differential—and provide output in forms such as 4-20mA, 0-10V, or digital communication protocols like HART or Modbus.

How Do Pressure Transmitters Work?

Pressure transmitters consist of a pressure sensor and signal conditioning electronics. The sensor detects pressure changes and converts them into a small electrical signal. The transmitter then amplifies and processes this signal into a standardized output, which can be used by control systems, PLCs, or data loggers to monitor and manage processes in real time.
