Differential pressure transmitter DE21 LCD


Differential pressure transmitter DE21 LCD

Our Fischer DE21 can monitor even the smallest differential pressures. It comes with a compact measuring instrument in 2-wire technology, serving to cover numerous measuring ranges in the low pressure area. To serve this purpose, capacitive measuring cells specially designed for nominal pressure ranges along with high overpressure safety are used. Owing to the fact that no signal spreading is required, these units ensure high precision, long term stability and drift free operation. Typical applications include the monitoring of laboratories, packaging machines, industrial furnaces, filters and blowers.

Main Features

  • High precision and long term stable capacitive sensor element
  • Measurement of lowest gauge, vacuum or differential pressure
  • High over-pressure protection
  • Selectable units mbar, Pa, kPa and inWC
