American Sensor Technologies offers its AST46HA Series of explosionproof pressure transmitter with extended pressure ranges, enhanced construction materials and new certifications to withstand varying harsh conditions present in offshore, marine, deep well drilling, oil processing and mining applications
With extended pressure ranges up to 1380 bar, the transmitter addresses the need for a high pressure, high cycle pressure transmitter in the drilling of deeper wells. Constructed of very thick diaphragms and state-of-the-art silicon strain gages, it offers repeatable results even in the hostile environs of deep well drilling.
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, the AST46HA possesses Class 2, Div 1, Group E, F and G (dust-ignition-proof) approvals for use in mining, cement and other dusty applications. It is also ABS approved for offshore and marine applications.
The addition of a Waspalloy material option, in addition to Inconel 718, 17-4 PH, Hastelloy C-276 and 316 L SS wetted parts, further extends these pressure transmitters' use in the processing of heavy oil and high sulfidation. A fail mode indicator option allows users to choose an output signal that rails or drops during a fault condition, providing better control on how their systems react should sensors failure. Vented and non-vented versions of the device are available along with F250C female process ports for robust high-pressure process connections.
