Single-stick tuning fork switch

Single bar vibrating material level switch is one of the tuning fork material level switch, it is not afraid of hanging material is not afraid of impact, no clamping problem, and more sensitive. Its cylindrical, single rod structure determines its wider adaptability to industrial sites. The single-bar vibrating material level switch uses the "resonance" principle of tuning fork to produce vibration under the drive of piezoelectric element. Only when the rod is surrounded by all materials, the vibration amplitude will be sharply reduced, thus producing switching action.

One, single bar vibration type material level switch characteristics:

1, Round smooth single rod probe, can effectively prevent clamping and sticky material;

2. It is not affected by the properties of the measured substance and installation conditions, and can be put into use stably without adjustment after installation;

3. The piezoelectric element is embedded in the rod body and the thick tube wall of the stainless steel probe, vibration suppression tube is only 9mm long (similar ratio is short), high stable vibration, heavy load resistance, long life;

4. Depending on the nature and specific gravity of the object to be measured, the sensitivity (high, medium, low) can be selected;

5, Use 15A large capacity contact relay switch, can directly control the motor;
