Switching off pumps when tank is full, to avoid overflow. For maintaining a constant level to avoid material wastage. For switching off pumps when running dry and indicating an empty tank to avoid wear and tear and production stoppage.Send Enquiry
Levtester SLWвЂ¦ series of level switches are successfully used in processing plants for conductive liquids of conductivity not less than 25 Вµ Siemens in Food, Power, Chemicals, Sugar, Detergents, Steel, Minerals, Textiles, etc.
A low AC voltage is applied between the probe electrode and the tank wall (or reference electrode in case of insulated tank). When the liquid comes in contact with the electrode tip, a conductive path is established between the sense electrode and the tank wall/reference electrode. This current is sensed, amplified and made to operate a relay whose contacts in turn can be used for annunciation/control.
