The tuning - fork - type level switch is a new - type levelswitch. The tuning fork is excited by a crystal to vibrate.When the tuning fork is immersed in materials, thevibration frequency changes. This frequency change isdetected by the electronic circuit and a switching value isoutputted. The tuning fork of the sensor vibrates at aninherent frequency. When the tuning fork touches liquid orother materials, its inherent vibration frequency decreases,and energy is consumed in the friction between materialparticles, forcing the amplitude to decay sharply and stopvibrating. The change in frequency activates the levelswitch, generating on - off signals.
