The AST4530 submersible pressure transducer features a rugged, compact design and offers excellent liquid and gas compatibility. Designed to measure the level of harsh liquids, the AST4530 features submersible PVDF cable, cord grip and housing. A cost effective alternative to ultrasonic & radar sensor technologies, the AST4530 includes a conduit connection for turbulent installations such as on-board ships, turbulent tanks, and rail cars.

The AST4530 has ranges up to 30 psi (or equivalent) and an accuracy of ±0.5% BFSL. The transducer works well with reflective liquids and will not fail due to vapor. Output can be either 0.5 to 4.5 V ratiometric, 1 to 5 V, or 4 to 20 mA. Cable lengths of 25, 50, or 75 feet are available.

The AST4530 is CSA certified to Class I Div 1, Groups C and D for use in intrinsically safe areas with an approved barrier.

Applications for the AST4530 submersible pressure transducer:

  • Chemical totes
  • Salt water holding tanks
  • Process plants
  • Rail-car liquid level monitoring
  • Storage tanks
