Hydrostatic level measurement
Fields of application
The FKE pressure transmitter can be used for any level measurement, on corrosive or non-corrosive liquids, and on tanks closed or open to the atmosphere.
Benefits
FKE direct-mount pressure transmitters in the FCX-AIV family accurately measure a liquid level and convert it into a directly proportional 4-20 mA output signal. The heart of the measuring element is a micro-capacitive silicon transducer that has proven its worth in the process industry.
The digital signal processing carried out by the electronic unit provides exceptional 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.
