Electromechanical lot system
NivoBob® - NB 3100
Continuous level measurement
Solids
bulk weight > 20 g/l (> 1.2 lbs/ft3)
The electromechanical plumb bob sensors NivoBob® NB 3100 is used for continuous level measurement in bulk storage silos of various applications. The simple electromechanical measuring method makes it a reliable all-rounder, approved in the practical use in almost all bulk solids. Especially in granulates or bulk solids with a low DK value, the NB 3100 works perfectly.
Durable, simple and reliable measuring principle up to 30 m measuring range
Works in almost all bulk granulates
Very sensitive due to very light sensing weight
