Milk Powder Level Sensor

Protocontrol offers the milk powder level sensor. It is a capacitive type point level sensor which will give indication as the level is reached. When the object enters in the sensing zone of the switch, capacitance between two plates of capacitor (one plate is represented by electrode at sensing .face of the switch and another by all surrounding material which is connected to the earth) changes. As soon as capacitance value crosses preset level, oscillator starts. This change is detected and resulted in an output signal.
