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
