Tips: Working Principle of the Tuning Fork Level Switch.
The working principle of the tuning fork level switch is to make the tuning fork vibrate at a certain resonance frequency through a pair of piezoelectric crystals installed on the tuning fork base. When the tuning fork of the tuning fork 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 level switch are measured, processed and converted into a switch signal by the intelligent circuit.
