Vibration level switch

Mononivo^® - MN 4020

Point level measurement
Solids
bulk weight > 20 g/l (> 1.2 lbs/ft3)

Application area

The vibration rod Mononivo^® MN 4020 is used in storage and process vessels as a full, demand, and empty detector in all bulk solids. A stainless steel probe extension allows the vibration rod to work in a variety of aggressive environmental conditions. Due to its high sensitivity, the probe is particularly suitable for use in very light bulk solids.

Your benefit

Maintenance-free sensor for use in many bulk materials. Particularly suitable for very light bulk solids
Extension completely made of stainless steel
Plug and play level limit switch without calibration
