Vibration level switch

Vibranivo® - VN 2050

Application area

The vibrating fork Vibranivo® VN 2050 is used in storage and process vessels as a full detector in many dry and free flowing bulk solids. The measuring probe can be flexibly adjusted up to a length of 20000 mm and puts the switching point where the application needs it. Due to its high sensitivity, the probe is particularly suitable for use in very light bulk solids.
