The AST4500 and AST4510 submersible level sensors are approved to Class I Div 1, Groups C and D for use in intrinsically safe areas with an approved barrier. From 0-1 to 0-100 PSI pressure / level measurement, this submersible pressure transducer is an excellent solution to level monitoring for indoor and outdoor applications.
The AST4500 and AST4510 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 level sensor operational for long-term use. Each submersible pressure transducer features a 1/2" conduit fitting at the electrical connection and removable nose cone at the sensor.
Available with voltage or 4-20mA output signals, AST can provide a cost effective submersible pressure transducer for level monitoring for a variety of applications.
