Vibration level switch

Vibranivo® - VN 6040

Application area

The Vibranivo® VN 6040 vibrating fork is used in storage and process vessels as a full and demand detector in many dry and free flowing bulk materials. The vibration fork is supplied as a kit for tube extension with a cable length of 1500 mm and 4000 mm. Thus, the customer himself defines the length of the probe via the tube length. Due to its high sensitivity, the point level probe is particularly suitable for very light bulk solids. The VN 6040 offers more space for wiring due to the larger housing and additionally a pressure-resistant design for use in the GasEx area.
