The GP-6400 series general-purpose pressure transmitters combine a high-precision sensing element with a dedicated signal-processing unit. They are built for harsh conditions — overload, pressure shock, icing, blockage and electromagnetic interference — and for long-term operation in demanding field environments.
The sensing element is welded into a 316L stainless steel housing with no internal sealing material in the pressure path, and the electronics sit on a damped PCB that tolerates vibration. The transmitter is available as a two-wire 4~20 mA current loop (9~30 V DC) or a three-wire 0/1~5/10 V voltage output (12~30 V DC), with gauge, absolute and sealed gauge pressure types across -1 bar to 1500 bar.
Typical use is hydraulic systems and test benches, oil and mining, water resources and hydropower, agricultural and construction machinery, and CNG or LNG installations. A wide option matrix — wetted material, electrical connector, accuracy class and pressure port — allows adapting the transmitter to a specific installation.
