Vertical Compact Liquid Level Switches

The VCS series of point liquid level switches demonstrates a high degree of reliability due to the use of non-reactive wetted components and a unique reed switch designed specifically for level sensing applications.  The sensor utilizes a moving float with an embedded magnet to activate a reed switch located in the sensor stem. As the liquid level passes the sensor, the float moves up or down on the stem giving a normally closed or normally open switch indication. The reliability of this sensor results from a very simple operating principle, a single moving part, media compatible wetted materials, and a unique reed switch design that has a UL recognized component certification. The sensor mounts into the top or bottom of a liquid storage tank from the inside (internal fitting) using either a 1/8” NPT or M8 x 1.25 threaded fitting. The output is a simple N.O. or N.C. SPST reed switch that utilizes Ruthenium contact points for reliability. Changing from a N.O contact to a N.C. output is done by removing the float, inverting it and re-attaching. This change can be done in the field. Electrical outputs are a single pair of wires with PVC insulation and optional lengths of 100 mm or 600 mm.
