Tuning fork level switch is a kind of new control switch, which is mainly depend on the tuning fork through the vibration principle to measure the level of material. Through the installation of the tuning fork on the base of the tuning fork vibration of a piezoelectric crystal in the resonance frequency. When the tuning fork and the medium contact, tuning fork frequency and amplitude changes, these changes are detected by the intelligent circuit, and converts it into a switch signal.
