BS/16 CN/16D Introduction
Sitron´s line of Conductive Level Switches offer a wide range of customized options to meet any application's need. CL models are designed to control the level of all conductive mediums with up to 5 different points of level detection. Models are available with Fixed rigid rods, Removable rigid rods, or with Pendular electrodes attached to the housing with cables. Applications involve both alarm point level detection as well as on/off pump valve control. Like all of Sitron's products, the series of Conductive Level Switches feature easy installation and maintenance free reliability. Technology
The probes work through the variation of the electrical resistance between the reference electrode and the level control electrode. Conductive Level Switches detect the level resistance when their electrodes are covered by the medium. An electrically conductive tank wall may be used as the reference electrode. If the tank is made of plastic, concrete or any other non-conductive material, an additional electrode is required to act as a reference.
