About differential pressure measurement

Proven in use in a wide range of applications in numerous industries: Differential pressure transmitters are used for the continuous measurement of differential pressures in liquids, vapors and gases. They are suitable for all types of media, both in standard applications and for applications with high process pressures and temperatures.

Measuring principle

The principle of differential pressure measurement is based on measuring the difference between two pressures. The differential value is output as a measurement result using a differential pressure transmitter.

Benefits

  • Universal differential pressure transmitters for flow, level and filter applications
  • Process temperatures from -70 to +400 °C are possible with diaphragm seals
  • Improved process availability and minimization of safety risks thanks to electronic differential pressure system
