Vibration level switch

Vibranivo® - VN 4040

Application area

The vibrating fork Vibranivo® VN 4040 is used in storage and process vessels as a full and demand detector in many dry and free flowing bulk solids. The measuring probe will be available as a kit for flexible tube extension with cable length of 1500 mm and 4000 mm. Thus, the customer himself defines the length of the probe by the length of the tube.
