Vibration level switch

Vibranivo® - VN 4030

Application area

The vibrating fork Vibranivo® VN 4030 is used in storage and process vessels as a full and demand detector in many dry and free flowing bulk solids. The measuring probe can be flexibly adjusted up to a length of 4000 mm and puts the switching point where the application needs it. A stainless steel probe extension allows the vibrating fork to work in a variety of aggressive environmental conditions.
