The piezoelectric component produces the resonation on the fork. When the fork comes into contact with a material, the fork will release some frequency signal as feedback
The LTU-2000 Tuning Fork Sensors are point level switches that are designed to detect low or high levels of liquids and is based on the vibrating tuning fork principle.
