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

Remote-sealed Differential Pressure Transmitters

Model No.

This is a microprocessor-based smart transmitter with excellent stability. It is suitable for measuring the differential pressure (flow rate, liquid level, etc.) of fluids that are highly corrosive or condensable, or fluids with deposited metal.

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

Advanced Transmitter Remote-sealed Differential Pressure Transmitters Transmitters (Model GTX_ _R) are used to measure differential pressure (flow rate, fluid level, etc.) of high-temperature or highly corrosive, condensable fluids. We offer an extensive lineup including small bore flange models starting at 40 mm and models for high temperature (including high temperature high vacuum) applications.
