Remote-sealed Gauge Pressure Transmitters

CEHART

AT9000 SuperAce Remote-sealed Gauge Pressure Transmitters (JTH series) are used to measure pressure (pressure, fluid level, etc.) of very hot as well as highly corrosive and condensable fluids. We offer an extensive lineup including small bore flange models starting at 40A and models for high temperature (including high temperature high vacuum) applications.
