Measure Levels of Harsh Liquids in Vented or Sealed Tanks with Submersible Pressure Sensors from American Sensor Technologies

The Model AST 4530 Submersible Liquid Level Pressure Sensor from American Sensor Technologies, Inc. (AST) is a designed to measure the level of harsh liquids such as slurries, salt water and oil in vented or sealed tanks.  Constructed with PVDF material and a PTFE diaphragm, the AST4530 Submersible Pressure Sensor features a submersible PVDF cable, cord grip and housing as well as a conduit connection for turbulent installations such as process plants, salt water holding tanks, on-board ships, turbulent tanks, and rail cars.  The submersible liquid level pressure sensor also works where fluid is reflective, has foam or is clear.  

Offering high reliable operations and long life, the PVDF Liquid Level Transducer will not fail due to vapor or condensation within a tank or vessel, is not affected from lid angle or proximity to tank wall and resists galvanic corrosion. A cost-effective alternative to ultrasonic and radar sensor technologies, the AST4530 Liquid Level Pressure Sensor offer a fast response time and is CSA certified to Class I Div 1, Groups C and D for use in intrinsically safe areas with an approved barrier.

Voltage and 4-20mA output signals allow users to interface for low current consumption or long distance transmission applications.  A 4 to 20mA output is the most common signal in monitoring applications that require long distance transmissions as the current can be read at the controller without signal loss for hundreds of feet. For either battery-powered or solar-powered applications, voltage output signal is ideal. Typically the solar panel will be located close the pressure sensor, so there is no signal loss in the cable.
