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.
