Explosion-proof transmitters

AST46HA series of explosion-proof pressure transmitters offer extended pressure ranges up to 20,000 psi, for use in high-pressure offshore applications. Thick diaphragms and silicon strain gauges offer high repeatability. Fail mode indicator option allows users to choose an output signal that rails or drops during a fault condition. Outputs include 4-20 mA; 0-5, 1-5, 1-6, 0-10, and 1-10 V; and 0.5-4.5 V ratiometric. Vented and non-vented versions and F250C female process ports are available.

In addition to Class 1, Div 1, Groups A, B, C, D approvals that make the transmitters suitable for use in acetylene and hydrogen environments, they possess Class 2, Div 1, Group E, F and G (dust-ignition-proof) approvals for use in mining, cement and other dusty applications. They are also ABS approved for offshore and marine applications.
