SC35 Series Tuning Fork Level Switch
Brand: FineTekThe piezoelectric component is used to drive the tuning fork and feedback signal, which produces the resonation on the fork.
When the fork comes into contact with a material, the fork will release some frequency signal as feedback.
It will be converted into the output of the contact signal when the circuit detects the frequency decrease of the signal.
The product relies on the damping effect by covering the testing material on the tuning fork which reduces the vibration frequency of the tuning fork and outputs a switch signal.
Therefore, there is no signal amplification circuit inside, which can eliminate the trouble of frequent sensitivity adjustment due to the material change.
