| FUNCTION |
|
| The electronically stimulated fork vibrates at its mechanically resonance frequency of 400 Hz when the fork is free of the service material. The resonance is caused by the piezoelectric crystals. One of the piezo crystals produces a small voltage which is transmitted to the switching amplifier. If the fork is covered by the bulk material, a damping effect is produced and the piezo crystal does not produce the voltage and the amplifier will switch and a corresponding signal output is actuated. The vibration of the fork has self-cleaning properties.The light deposit on the container wall does not affect the operation of the AQUAFORK |
