Working principle The vibration probe set vibrating piezo-electrically. If the vibration
sensor is covered by the filling material the resonant frequency changes.
This change is registered by the electronics and converted into a switching
command.
Area of application As a limit switch for registering limits in liquids e.g. overflow and
dry running protection. The vibration probe technique can be particularly
advantageous for use in small containers or pipelines.

Stainless steel, Hastelloy C, ECTFE coated, or enamelled.
Output
Switched output (Switch, relay, transistor or initiator).
Fitting and Types
Cylindrical housing; Fitting by means of flanges or threads. Maximum length
