SPC660 Capacitive liquid level switch electrode integrated in the sensor probe by frequency scanning technology and the surrounding environment together form a capacitance whose value depends on the dielectric constant of the medium. The capacitor and inductor coils in the sensor circuit together form a resonant circuit. Switching signals can be triggered based on the measured resonant frequency and an adjustable switching action range.
