Absolute pressure measurement
Fields of application
The FKA - NC - K3 absolute pressure transmitter provides precise measurements of any pressurized gas or fluid, while using a fixed vacuum pressure as a reference for nuclear applications.
Benefits
FKA pressure transmitters in the FCX-AIV family accurately measure absolute pressure and convert 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 SIL2 (HFT=0) and SIL 3 (HFT=1) in accordance with standards IEC 61508 and IEC 61511.
