Gauge Pressure Transmitter (FKG Traditional Mount & FKP Direct Mount)

The FKG and FKP models of high precision relative pressure sensors are capable of accurately determining relative pressure and then sending a corresponding 4-20 mA electrical output signal. The transmitter uses the most advanced digital signal processing and a silicon micro-capacitive sensor for unmatched accuracy, stability and reliability.

  • Precise measurement of relative pressure
  • Independent of environmental conditions thanks to GyrationTM 4D characterisation
  • Reliable, robust with high availability.
