Working principle:

The LD series level switches are based on the variation of the natural resonant frequency of a vibrating fork when it comes into contact with a liquid or a solid. This variation is detected by the internal electronics and is used to determine the state of the output.

Applications

• Pump control
• Open and pressurized tanks, tanks with agitation
• Open channel and empty / full pipe detection
• Distillation columns and evaporators
• Chemical dosing tanks
