Level Measurement | Capacitive Level Sensors | Capacitive Limit

An insulated metal probe mounted in a metal container forms a capacitor together with the metal wall whose capacitance continually increases as the medium level increases. Hence, for capacitive measurements a medium with a constant permittivity is required. The simple and robust construction (as rod or rope sensor) allows level measurement of liquids, granular solids,
