Differential Pressure Transmitter / Pressure Transmitters Advanced Transmitter Model GTX_ _ _

Flange-Mounted Differential Pressure Transmitters

Model No.

This is a microprocessor-based smart transmitter with excellent stability. It can be mounted on a flange on the side of a tank to measure the liquid level, interface level or specific gravity in the tank.

  • Safe instrumentation: IEC 61508-compliant and SIL2-certified
  • Excellent usability: zero/span adjustment without opening the cover
  • Various functions: send alarm information by contact output (optional)

Advanced Transmitter Flange-Mounted Differential Pressure Transmitters (Model GTX_ _F) can be attached to a tank-side flange to measure fluid level, specific gravity, etc. We offer an extensive lineup ranging from 40 mm small bore models to 100 mm protruding flange models.
