Vibration Type Level Switch KVK/KVA/KVF Series

The vibration type level switch stably detects materials even with unstable relative permittivity and electrical properties! Granules with an apparent specific gravity 0.03 or more can be detected.

Features

It detects materials with unstable relative permittivity and moisture percentage etc
Excellent pressure-proof performance with its stainless steel integral structure
It can detect granules with an apparent specific gravity 0.03 or more
For intrinsically safe model (KVS), rod for high sensitivity or for heavy load can be selected

Operating Principles

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