The AST4500 and AST4510 submersible pressure transducers 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, these submersible pressure transducers are 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 sensor operational for long-term use. Each submersible sensor now features a conduit fitting at the electrical connection for applications requiring a rigid installation, such as a turbulent tank or onboard shipping application.
With a removable nose cone, the AST4500 and AST4510 series can also be installed outside of the tank through a 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 4-20 mA output signals, these units can also be ordered with an additional 4-20 mA temperature output.
