SP-YC series tuning fork level switch is based on the principle that the electric circuit signal energizes the crystal in the fork which makes the probe of the tuning fork virbate at a certain rate. When the probe is completely whelmed by the material measured, the vibration frequency of the fork will be changed, then the electric circuit of the meter can automatically detect the difference and transfer it into switch signal which will be output by the replay for on-spot alarming and remote control; When the material departs from the probe, the meter restores to the normal working condition to detect the changes of material level.

Features:
1. Compact structure, applicable for top or side mounting
2. Complete electric circuit design, with no need of maintenance after operation
3. Wide applications, the physical property of the materials measured has no influence
4. Special tuning fork design and its inherent vibration characteristic which ensure the function of automatic elimination and maximally prevent material hanging.

Applications:
1. Tap water, mineral water
2. Pulp, glue, dye
3. Sewage, mud, acid-base solution
4. Material control in fields of power plant, steel, cement and etc.
5. Beer, beer fermentation agent, beverage and other liquids which can generate gas.
