Clark Solutions Conductive Level Switch FK10

Model series FK10 conductive level switches are intended to be used with the FKE electrode relay for detecting the level of conductive fluids. An A.C. voltage is applied to an electrode insulated from the tank. When the electrode is wetted by the process fluid, a low current flows from the electrode through the fluid to the tank wall (in the case of plastic tanks, the current flows to a ground electrode). This current flow is detected by the electrode relay and output as a switching signal. To detect the fill limit in tanks containing conductive fluids To report whether the tank is empty or full To switch over between two filling heights To provide overflow protection To provide dry-running protection
