Absolute Pressure Transmitter (FKA & FKH High Accuracy)

The FKA high accuracy absolute pressure transmitter model and FKH high accuracy absolute pressure transmitter model accurately measure an absolute pressure and transmits a proportional 4-20 mA output signal.

The transmitter uses a unique high reliability micro-capacitive silicon sensorin combination with a state-of-the-art digital signal processing to provide exceptional performances in terms of accuracy and stability.

  • Short delivery time
  • Accurate measuring results independent of atmospheric conditions
  • Significant process performance thank to 4D Gyration TM characterization
  • High plant availability thanks to high reliability unique design
