FKB, FKD & FKM Gauge, Differential and Absolute Pressure Transmitter for Remote Seal(s) with Safety Functions

Exceptional performance in accuracy, long term stability and functionalities

The FCX-AII VG Series FKB, FKD & FKM gauge, differential and absolute pressure transmitters for remote seal(s) with safety functions use the unique and proven silicon sensor with state-of-the-art digital processing to provide exceptional performance in terms of accuracy, long term stability and functionalities. The Advanced Floating Cell design, which protects the pressure sensor against changes in temperature, static pressure and overpressure, substantially reduces total measurement error in actual field applications.

The transmitter with safety functions complies with Safety Integrity Level (SIL) 2 and 3.
