Impedance Spectrum Level Switch

Principle

The CSF112 series impedance spectrum level switch determines the capacitance value at the end of the sensor and the dielectric constant value of the medium through a high-frequency electric field. Due to the difference between the dielectric constant of air and the dielectric constant of the medium, therefore two states can be identified, the end of sensor is covered and uncovered, thus performing switch to achieve high and low level detection and alarm.
