Feature

VIBRATION TYPE LEVEL SWITCH　KVK/KVA/KVS/KVF Series

The vibration type level switch stably detects even substances with variations of the relative permittivity and electrical properties!

It detects even measured substances with variations of properties such as relative permittivity and moisture percentage.
As it has a stainless steel integral construction, it has an excellent pressure-proof performance.
It can detect granules with an apparent specific gravity of 0.03 or more.
For the intrinsic safety explosion-proof (KVS) type, either a high-sensitivity rod or load bearing rod can be selected.

Operating Principles

The vibration rod is operated by the vibration element built in the sensing unit. When the rod touches the measured substance, the vibration is attenuated. This is detected electrically and the contact is output.
