        The working principle of tuning fork level switch is that the probe is based on the tuning fork design, adopts piezoelectric devices to realized the vibration driving and detection of the fork body. When not in contact with materials, the tuning fork will vibrate at the resonant frequency; once it is contacted by the materials, the vibration amplitude of the tuning fork decreases obviously, and the output signal amplitude of the piezoelectric detection device decreases accordingly. The signal change will be detected and analyzed by the intelligent circuit and a switching signal will be output.
