Inductive level switch
Basically an inductive level switch works on the principle of electromagnetic radiation and eddy currents. And it uses an oscillator resonant circuit that uses a core magnetic coil to generate a strong electromagnetic field. When this field penetrates the media, it creates eddy currents that reduce the amplitude of the oscillations. This switch changes the electrical output.
