Vibration level switch
Vibranivo®
Point level measurement
Solids
bulk weight < 5 g/l (> 0.3 lbs/ft3)
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.
Maintenance-free sensor for use in many bulk materials. Particularly suitable for very light bulk solids
Probe extension adjustable up to a length of 20000 mm
Plug and play level limit switch without calibration
