Liquid level sensors include ½" NPT male conduit fittings

Wed, 08/29/2012 - 10:53am

LISTED UNDER:

American Sensor Technologies, Inc. (AST) now supplies its liquid level sensors with ½" NPT male conduit fittings before the cable interface. Certain customers prefer to install conduit over a cable. This is beneficial if the sensor is going to be exposed to a liquid not compatible with the material, as well as adding stability in turbulent tanks. For installations where the level sensor is threaded into a tank, customers prefer to install conduit to protect the cable from the work environment. 

AST4500, AST4510, and AST4520 level sensors are Class I Division 1 intrinsically safe, Groups C and D when installed with a barrier as well as ABS (American Bureau of Shipping) certified. This allows the sensors to be used in remote monitoring and telemetry applications where liquids and gases are in hazardous environments.  Pressure ranges are available as low as 0-1 PSI (27.68 inches water column). Voltage output signals are typically chosen for applications with low power and low current consumption, whereas 4-20mA is used for long distance transmissions.

The only non-hazardous area approved level sensor is the AST45PT, which combines pressure and temperature monitoring in a single device.
