American Sensor Technologies Inc. (AST) has added two new devices to its pressure product line, the AST44LP and AST43LP low-pressure, hazardous area-approved pressure transmitters.

These media-isolated, stainless steel units can be used in industrial applications and are claimed to offer the best price-to-performance ratio in the industry. Both low-pressure transmitters are constructed with 316L SS wetted materials for complete compatibility with a wide range of liquids and gases.

AST44LP carries an UL/cUL 913 (CSA 157) approval and has been rated for Class 1 Division 1 Groups C & D when installed with an approved barrier. This high-strength unit measures low pressure ranges from 0-5 to 0-15psi and is intended for intrinsically safe areas.

Like the AST44LP series, AST43LP also measures low pressure ranging from 0-5 to 0-15psi. The device is recommended for use in hazardous locations. AST43LP is UL/cUL 1604 (CSA 213) Class 1 Division 2 Groups A, B, C & D listed.

Common applications for both pressure transmitters include industrial OEM equipment, water management, hydraulic systems, control panels, HVAC/R equipment, gas compression and storage, vapor recovery and external tank leveling.

The standard fittings available for both products include 0.5-inch NPT Male and 0.4375-inch 20 UNF Male. To simplify system integration for existing application and provide flexibility for new system designs, the AST43LP and AST44LP can be packaged with several electrical options. Both units offer assorted cable lengths with conduit fittings or a Hirschmann DIN 43650A. AST44LP is also equipped to provide alternative options such as standard cable, mini DIN 43650, Bendix or Packard Metripack 150 three-pin connection.

AST said that its AST4300, AST4310, AST4400 and AST4410 products will now have the DIN 43650A option. The large DIN allows for the unit to be easily installed, repaired or removed independently from the controller. Moreover, the DIN 43650A supplies another option for new designs and a drop in replacement for existing applications.
