Tuning fork vibrating level switches, by resonant piezoelectric crystal to cause their vibration,When subjected to material damping. Drastically reduced the amplitude and the frequency and phase of significant change. These changes will be detected by the internal electronic circuits, and then after treatment, converted into a switching signal.
It is practical and simple, reliable, and applicability; Tuning fork and output were working condition, all with LED indication; It may indicate that under customary adjustment; A variety of input and output.
The industry level switches can be used for the high and low level of material tank, for a variety of liquid, powder, granular solid.
