Net capacitive Level switch




Ultra-high sensitivity type


DITECH’s proprietary net capacitive level switch is immune to the influences of electrical conductivity variations and offers the highest sensitivity among electronic level switches.


Every liquid, granular material and powder is more than a simple dielectric material: they exhibit various electrical characteristics.

Common capacitive level switches capture overall changes in electrostatic capacitance to output detection signals. The DLS model detects net changes in electrostatic capacitance by accurately correcting changes in electrical conductivity and therefore offers ultrahigh sensitivity.
