Pressure measurement with diaphragm seals
Fields of application
A pressure transmitter with analog diaphragm seal for nuclear applications enables: liquid flow measurement, gas flow measurement, steam flow measurement, fluid level measurement in a tank, fluid density measurement or pressure measurement at low or high temperatures.
Benefits
The FYB analog transmitter is a device that precisely measures gauge pressure and converts it into a directly proportional 4-20 mA output signal. The heart of the measuring element is a Silicon micro-capacitive sensor, offset in the neck of the cell, providing exceptional performance. The FYB series is specifically designed for safety in nuclear applications requiring high reliability and long life in harsh environments (radiation with a Total Integrated Dose of 50kGray).
