SE Capacitance Sensor Bin Level Indicator

Working Principle of our SE Capacitance Silo Bin Level Indicator

The probe (inductive pole) of the level switch and the container wall (earth ground) are used as the two polar plates of the capacitor. As the medium between the two plates changes, the capacitance changes accordingly. The special analysing and processing unit of the level switch detects the range of the changes. When the change is up to the set value of the switch, it is converted into switch signal output for control. In this way, it further reflects the height of the measured medium or the liquid level.
