The working principle of the tuning fork level switch is to vibrate the tuning fork at a constant resonance frequency through a pair of piezoelectric crystals installed on the base of the tuning fork. When the tuning fork is in contact with the measured medium. The amplitude and frequency of the tuning fork will mutate, which the intelligent circuit detects and converts this change into a switching signal
Strong adaptability: Different electrical parameters and density of the material to be measured do not affect the measurement.
Free from maintenance: Because the detection process of the tuning fork limit switch is completed by the electronic circuit, no moving parts, so once installed and put into operation, no maintenance is required.
