Pressure measurement with diaphragm seals
Fields of application
A nuclear analog differential pressure transmitter with diaphragm seal for nuclear applications allows: liquid flow, gas flow, steam flow, level measurement of a fluid in a tank, density measurement of a fluid or pressure measurement at low or high temperatures.
Features
The FYD analog transmitter is a device that accurately measures differential 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 cell neck, enabling exceptional performance. The FYD 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).
