FYB & FYD Analog Gauge and Differential Pressure Transmitter for Remote Seal(s)

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

The FYB & FYD analog gauge and differential pressure transmitters for remote seal(s) accurately measure gauge pressure and transmit a proportional 4-20 mA output signal.

FYB and FYD series are specially designed for safety related applications encountered in nuclear power plants where high reliability and long lifetime under mild to harsh environment are required (radiation with total integrated dose (TID) 50 kGray).
