Liquipoint is a point level sensor with tuning fork for point level detection. It is designed for industrial use
in all areas of process technology, but preferably in liquids. The vibrating element (tuning fork) is piezoelectrically energized and vibrates at its mechanical resonance frequency. The piezo elements are mechanically fixed and are hence not subject to temperature shock limitations. If the vibrating element is submerged in the product, the vibrating frequency changes. This change is detected by the integrated electronics module and converted into a switching command.
Typical applications are overfill and dry run protection. Thanks to its simple and robust measuring system, liquipoint is virtually unaffected by the chemical and physical properties of the liquid.
