American Sensor Technologies has upgraded its AST46HA and AST4600 series of explosion proof pressure transmitters with new materials, options and pressure ranges.
AST46HA-Factory-Sealed pressure transmitter
The pressure transmitter improvements allow the company to meet customer demands as well as applications in different types of industries. For instance, American Sensor Technologies can meet the requirement for high cycle pressure transmitters while drilling deeper wells by increasing the pressure limits of its explosion-proof pressure transmitters to 20,000 PSI. Adding a Waspalloy material option reinforces the use of pressure transmitters in the treatment of high sulfidation and heavy oil. A fail mode indicator option helps customers to control their systems in case of sensors failure.
The pressure transmitter features extended pressure that ranges from 0-2.5 to 20,000 PSI. It contains F250C female process ports that can be utilized for high-pressure process connections. The pressure transmitter comes with a vented gauge reference that enables for low pressure ranges.
Class 1, Div 1, Groups A, B, C, D approvals meant for the AST46HA series make the pressure transmitter ideal for hydrogen and acetylene environments. Sealed gauge versions are certified for Class 2, Div 1 Groups A, B, C, D and suitable for installations and applications in the mining industry.
In addition to Inconel 718, 17-4 PH and 316 L SS., the Waspalloy wetted material option is provided for both pressure transmitters. Waspalloy, made of cobalt-based alloy material, is impervious to corrosion, especially to H2 and H2S. A failure mode indicator option, present in the AST64H, enables the customer to select an output signal that can drop or rail at the time of a fault condition.
American Sensor Technologies worked along with CSA International to improve the existing approval file in order to incorporate the new pressure transmitter features.
