Submersible Pressure/level Transmitters

These Submersible Pressure/Level Transmitters are approved to UL/cUL913 (CSA 157) Class I Div 1, Groups C and D for use in intrinsically safe areas with an approved barrier. For pressure ranges from 0-1 to 0-100 PSI that require a wide range of media compatibility, this submersible series is an excellent solution to level monitoring for indoor and outdoor applications.
The AST4500 and AST4510 liquid level sensors are completely sealed for submersion, yet vented through the cable to correct for barometric pressure changes. The welded housing is tested in-house via a helium leak tester to ensure proper protection. The conductors of the cable are also isolated from the outside environment to keep the sensor operational for long-term use. Each submersible sensor now features a 1/2" conduit fitting at the electrical connection for applications requiring a rigid installation, such as a turbulent tank or on-board shipping application.
