This is a microprocessor-based smart transmitter with excellent stability. It can measure the flow rate and pressure of gases, liquids, and steam, as well as liquid levels.

  • Safe instrumentation: IEC 61508-compliant and SIL2-certified
  • Excellent long-term stability: zero point drift of only ±0.1 % over 10 years
  • High-speed response within 100 ms for turbines and other applications that require fast response

Advanced Transmitter Differential Pressure Transmitters (Model GTX_ _D) are used to measure the flow rate of gases, liquids, and steam, to measure tank fluid levels, etc. They provide high accuracy of ±0.04 % together with long-term stability (zero drift of only ±0.1 % over 10 years), greatly reducing calibration work after installation.
Other models measure minute pressure differences as low as 0.1 kPa, or withstand pressures as high as 42 MPa.
