Overview of vibrating rod level switch:

The vibrating rod level switch is suitable for fixed-point alarm or control of various material levels in silos and liquid levels in containers, and can detect sediment in liquids! The instrument has no movable parts and is corrosion-resistant with high sensitivity

And features such as easy installation. Solid materials: rice, milk powder, sugar, salt, laundry detergent, cement, stone powder, plastic pellets, etc; Liquid media: water, mud, pulp, dyes, oils, milk, alcohol, beverages, etc

Working principle of vibrating rod level switch

The vibrating rod level switch utilizes the "resonance" principle of a tuning fork. The vibrating tube and the built-in vibrating rod form a "tuning fork" resonance probe with a frequency of 280Hz, which vibrates under the drive of piezoelectric elements. When the probe

When the measured object is touched, the amplitude of the vibration decreases and is converted into an electronic signal, causing the relay switch to operate.

Electrical connection of vibrating rod level switch

After connecting the power supply, the device enters normal operation with a 5-second delay. When the upper limit alarm is triggered, the limit will be activated

Select to dial up, and when the lower limit alarm occurs, select to dial down the limit.

Turn the sensitivity selection to the top for high sensitivity and to the bottom for low sensitivity.

Sensitivity adjustment: counterclockwise direction increases sensitivity, clockwise direction decreases sensitivity.
