Vibranivo® - VN 4020
Vibration level switch
Vibranivo®
Point level measurement
Solids
bulk weight > 30 g/l (> 3.8 lbs/ft3)
The vibrating fork Vibranivo® VN 4020 is used in storage and process vessels as a full, demand, and empty detector in many dry and free flowing bulk solids. The short extension enables the probe to withstand high mechanical loads. Its stainless steel probe extension allows the vibrating fork to work in a variety of aggressive environmental conditions.
Maintenance-free, very cost-effective sensor for use in many bulk materials
Extension completely made of stainless steel
Plug and play level limit switch without calibration
