Tuning Fork Level Switch is a mechanical resonant device which is excited by piezoelectric (PZT) elements. When the measured medium comes into contact with the tuning fork, it will change the feedback resonant frequency due to the damping resonances between the exciting PZT and receiving, PZT.
By detecting the frequency and appropriately tuning the sensitivity of Tuning Fork Level Switch on measured material, such device can easily operate for monitoring the alarm level of measured material.
