Applications

 Water and fuel storage tanks  Pump on/off controls  Marine bilge and ballast tanks  Flood detection and prevention  Coolant level indication  Livestock watering tanks  Irrigation systems  Water treatment plants  Waste water tanks  Chemical storage and processing Two position level switching Mounted on the top wall of a tank Reliable hermetically sealed reed switches Body and float made from inert materials The EVS series of point liquid level switches demonstrate 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 one of two reed switches located in the sensor body. As the liquid level raises the float, it moves a magnet from the bottom switch to the top switch. The use of two switches provides an indication of three different level conditions. 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. The sensor mounts into the top wall of a liquid storage tank using an M16 x 2.0 threaded fitting. The M16 mount is available in an internal or switches that utilize Ruthenium contact points for reliability. Electrical outputs are three wires with PVC insulation and optional lengths of 0.5 m or 2.0 m. CLICK HERE › CONNECT WITH A SPECIALIST
