Specifications

The FKR high-pressure transmitter is an intelligent transmitter for measuring very high relative pressures, up to 150 MPa (1500 bar, 21,750 psi or 150,000 kPa). It is based on a piezoresistive silicon transducer combined with digital signal processing, guaranteeing high accuracy and excellent long-term stability. Designed to meet the extreme demands of multiple industrial applications, it is perfectly suited to pressure monitoring in wellheads, injection lines, hydraulic presses, plastic injection machines, hydrostatic testing, chemical reactors. Thanks to its HART™ 7 compatibility, no-open local configuration options and robust materials, the FKR pressure transmitter offers reliability, safety and flexibility in the harshest environments.
