Vibration level switch
Vibranivo® - VN 2020
Point level measurement
Solids
bulk weight < 5 g/l (< 0.3 lbs/ft3)
The vibrating fork Vibranivo® VN 2020 is used in storage and process vessels as a full, demand, and empty detector in many dry and free flowing bulk solids. Due to its high sensitivity, the probe is particularly suitable for use in very light bulk solids. The high surface quality of the stainless steel probe also makes it ideal for use in applications with hygienic requirements.
Maintenance-free sensor for use in many bulk materials. Particularly suitable for very light bulk solids
Extension is completely made of stainless steel
Plug and play level limit switch without calibration
