The Rosemount Analytical Model 150 Insertion/Submersion Sensor is available in sensor constants of 0.1, 0.5 or 1.0 for conductivity ranges from 0-10 to 0-10,000 μS when used with Models 54eC, 81C, 1054BC, 1181C, 2081C, and 3081C analyzers/transmitters. For optimal loop performance, connect the Model 150 sensor to instrument Models 54eC or 1054BC.

The Tefzel housing has both rear-facing and forward-facing, 1 inch male pipe threads. The sensor can be threaded into a process line or the side of a tank, or be attached to a length of pipe for submersible installation. The Model 150 is available with a 1 inch CPVC tee (Code 16) for flow-through installation. An integral 10 foot cable is supplied for connection to the analyzer/transmitter or junction box.

This sensor is most appropriately used as a set-point detector in applications with a fairly broad control range. This sensor is a good choice for boiler blowdown and open recirculating cooling water. For applications that require high accuracy over a wide range of conductivity, a sensor from the ENDURANCE™ family (Model 400 series) or the toroidal family (Model 200 series) would be the ideal choice.
