Operating Instructions
4. Description
This level switch instruments for solids NSC, has been designed to be used in all
applications where the level of the solid must be detected in tanks and silos.
5. Operating principle
The NSC sensor together with the wall of the tank is a capacitor.
The dielectric constant of this capacitor is the air when the product (media) doesn’t
reach the sensor. When the product covers the sensor, the dielectric constant is
the product one. The electronic circuit of the NSC detects this change and
activates an output relay.
