At the heart of the measuring element is a micro-capacitive silicon transducer highly proven 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.
