GTX35R/GTX40R

AT9000 Advanced Transmitter Remote-sealed Differential Pressure Transmitters (GTX**R series) 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.

Excellent long-term stability

Zero drift: long-term stability of only ±0.1 % drift over 10 years

Fast response

Response speed: 100 ms or faster; can be used in applications that require fast response.

Wide measuring range (rangeability)

This single model offers a wide measurement range, which is very useful for both expanding the scope of measurement and reducing the equipment needed. Rangeability 1:400

Very user-friendly

Zero/span adjustment can be done without opening the cover.

Multiple functions

Historical data (e.g., on excessive pressures or abnormal temperatures) can be retrieved by a communicator.
