Azbil GTX35R/ GTX40R Remote-sealed Differential Pressure Transmitters

Manufacturer: Azbil Corporation
Model: GTX35R/ GTX40R

Feature

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)

Summary

Advanced Transmitter Remote-sealed Differential Pressure Transmitters (Model GTX_ _R) measure the differential pressure (flow rate, fluid level, etc.) of high-temperature, highly corrosive, or 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.
