Pressure transmitter FKE FUJI ELECTRIC
Hydrostatic Level Transmitter – Level Measurement
Fields of application
The pressure transmitter FKE can be used for any level measurement, on corrosive or non-corrosive liquids, and on tanks closed or open to the atmosphere.
Key Features:
- High precision and long-term stability
- Flexibility of use
- Minimal influence on the environment
- Integrated linearisation function
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 offers 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.
