Differential pressure transmitter - FKC
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 IEC 61508 and IEC 61511 standards.
