FKB, FKD & FKM Gauge, Differential and Absolute Pressure Transmitter for Remote Seal(s)

EDF “Not Classified” version and EDF “K3 Classified” version for Nuclear Applications

The FKB, FKD & FKM gauge, differential and absolute pressure transmitters for remote seal(s) accurately measure pressure and transmit a proportional 4-20 mA output signal.

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