Tuning fork level switch technical indicators

The tuning fork liquid level switch works by vibrating the tuning fork at a certain resonant frequency through a pair of piezoelectric crystals mounted on the tuning fork base. When the tuning fork of the tuning fork liquid level switch is in contact with the measured medium, the frequency and amplitude of the tuning fork will change. These changes of the tuning fork liquid level switch are detected by the intelligent circuit, processed and converted into a switching signal.
