Mt. Olive, N.J. American Sensor Technologies, Inc. (AST) has released two low-pressure, hazardous area-approved pressure transmitters. The AST44LP and AST43LP devices are media-isolated, stainless steel units aimed at a variety of industrial applications. Both low-pressure transmitters are constructed with 316L SS wetted materials for complete compatibility with a wide range of liquids and gases.
The 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 0-15 PSI and is intended for intrinsically safe areas.
Similar to the AST44LP series, the AST43LP also measures low pressure ranges from 0-5 to 0-15 PSI, but it is recommended for use in hazardous locations. The 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 1/4-inch NPT male and 7/16-inch-20 UNF male. To simplify system integration for existing applications and to provide flexibility for new system designs, the AST43LP and AST44LP can be packaged with a variety of electrical options. Both units offer assorted cable lengths with conduit fittings or a Hirschmann DIN 43650A. The AST44LP is also equipped to provide alternative options such as: standard cable, mini DIN 43650, Bendix or Packard Metripack 150 3-pin connection.
AST also announces that the following products will offer the DIN 43650A option: AST4300, AST4310, AST4400 and AST4410. The large DIN allows for the unit to be easily installed, repaired or removed independently from the controller, said AST.
