Vibration level switch

Mononivo® - MN 4030

Application area

The vibration rod Mononivo® MN 4030 is used in storage and process vessels as a full and demand detector in all 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.
