Pressure measurement with diaphragm seals
Fields of application
A pressure transmitter with diaphragm seal for nuclear applications can be used to measure liquid flow, gas flow, steam flow, fluid level in a tank, fluid density or pressure at low or high temperatures.
Benefits
The FCX-AII series pressure transmitter is an electronic device that accurately measures differential, relative or absolute pressure and converts it into a directly proportional 4-20 mAcc output signal. It is used to measure differential, absolute and relative pressure, flow, level or density. The heart of the measuring element is a silicon micro-capacitive sensor. In addition, the electronic unit benefits from the latest microprocessor technology.
