SPST output Mounted on the side wall of a tank Certified reed switch (UL component listed) Body and float made from glass filled nylon 6.6 The LDS 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 body. As the liquid level raises the float, it moves a magnet into close proximity of the reed switch and actuates it to give an open contact or closed contact 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 side wall of a liquid storage tank using an M16 x 2.0 threaded fitting. The M16 mount is available in an SPST reed switch that utilizes Ruthenium contact points for rotating the switch 180° in the mounting hole. This change can be done in the field. Electrical outputs are a single pair of wires with PVC insulation and optional lengths of 0.5 m or 2.0 m. CLICK HERE › CONNECT WITH A SPECIALIST
