American Sensor Technologies' AST44LP and AST43LP are constructed with 316L SS wetted materials for complete compatibility with a wide range of liquids and gases.
American Sensor Technologies (AST) has released the AST44LP and AST43LP low-pressure, hazardous area-approved pressure transmitters.
These media-isolated, stainless steel units can perform in a variety of industrial applications and hold 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.
The AST44LP carries an UL/cUL 913 (CSA 157) approval and has been rated for Class 1 Division 1 groups C and D when installed with an approved barrier.
This high-strength unit measures low-pressure ranges from 0-0.3 to 0-1bar and is intended for intrinsically safe areas.
Similar to the AST44LP series, the AST43LP also measures low-pressure ranges from 0-0.3 to 0-1bar, 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 and 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, vapour recovery and external tank leveling.
To simplify system integration for existing application and 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 three-pin connection.
Along the same lines, AST announces that the following products will now also have the DIN 43650A option: AST4300, AST4310, AST4400 and AST4410.
This option helps to expand AST's evolving product line while providing an added benefit to the consumer and/or application.
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.
