Theelectronically stimulated fork vibrates at its mechanicallyresonance frequency of about 400 Hz when the fork is free of theservice material. The resonance is caused by the piezoelectriccrystals. One of the piezo crystals produces a small voltage which istransmitted to the switching amplifier. If the fork is covered by thebulk material, a damping effect is produced and the piezo crystaldoes not produce the voltage and the amplifier will switch and acorresponding signal output is actuated. The vibration of the forkhas self-cleaning properties.
