Pressure Transmitter



The DP-Switch has been designed to automatically stop the refueling process when the maximum permitted differential pressure for filter elements is reached. The FAUDI Aviation DP-Switch is designed for connection to a mechanical differential pressure gauge that measures the pressure difference between the inlet and outlet of a filter vessel in safety-critical applications.

The switching pressure is set to 1 bar (15 psi) and designed to stop the refueling process automatically. It is suitable for competitive exchange and easy to retrofit.


  • Conformity with JIG Bulletin No. 58
  • Switching pressure at 1.0 bar (15 psi)
  • Easy installation to a differential pressure gauge
  • Establishing a connection with an existing deadman switch
