Differential pressure measurement
Fields of application
The pressure transmitter differential FKC is used in various applications such as level measurement, flow measurement, density measurement, filtration and interface measurement.
Benefits
The FCX-AIV family of FKC pressure transmitters precisely measures differential pressure, liquid level or flow, and converts it into a directly proportional 4-20 mA output signal. At the heart of the measuring element is a micro-capacitive silicon transducer with a proven track record in the process industry. The digital signal processing carried out by the electronics unit ensures outstanding accuracy and stability. The FCX-AIV family of pressure transmitters complies with integrity and safety levels SIL 2 (HFT=0) and SIL 3 (HFT=1) in accordance with standards IEC 61508 and IEC 61511.
