Description
Electronet Series CLS-01 are capacitance-type level switches designed for accurate point-level sensing.
The vessel wall and probe act as two electrodes forming a capacitor. For non-conductive vessels, a coaxial probe is used.
The capacitance varies based on the dielectric constant of the material surrounding the probe—air has a value of 1, while liquids have higher values.
As material level changes, the capacitance changes accordingly, triggering a switching output at the preset point.
This makes CLS-01 ideal for reliable level detection in industrial applications.
