AST4500/AST4510
Level Sensors, Tank Level, Water Level Transmitter
The AST4500 and AST4510 submersible level sensors 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 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.
With a removable nose cone, the AST4500 and AST4510 series can be also be installed outside of the tank through a 1/4" NPT pipe connection. In this configuration, the sensor continuously monitors the tank level through a threaded connection outside the tank, yet remains fully submersible for applications with flood prone environments or severe wash-down conditions.
Available with voltage or 4-20mA output signals, AST can provide a cost effective solution for level monitoring for a variety of applications.
Note: ABS approval with CSA approved version.

Warranty
Workmanship - AST4500 and AST4510 level sensors have a limited one-year warranty to the original purchaser. AST, Inc. will replace or repair, free of charge, any defective level sensor. All units returned for warranty evaluation must be thoroughly cleaned and free of process residue prior to shipment. Units that are not properly cleaned will be discarded and warranty service will be denied. This warranty does not apply to any sensors that have been modified; misused, neglected or installed where the application exceeds published ratings. AST4510 is not recommended for use with hydrogen. AST's sensors are made with pride in New Jersey, USA. If in the area please feel free to stop by for a visit!
Installation/Applications - The purchaser is responsible for media compatibility, functional adequacy, and correct installation of the level sensor. The nose cone is installed on the sensor with Loctite ®. To remove, hold the sensor by the hex with a wrench. Put a screwdriver through both holes of the nose cone and turn counterclockwise. The level sensor will have a 1/4" NPT Male pressure port.
