The AST4500 and AST4510 submersible liquid 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. It

is also certied for ATEX Class I Zone 0 Exia IIB T4 Ga (Ta = -40°C to +80°C). For pressure ranges

from 0-1 to 0-100 PSI that require a wide range of media compatibility, the 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 conguration, the sensor continuously monitors the

tank level through a threaded connection outside the tank, yet remains fully submersible for applications

with ood 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.
