NivoBob® - NB 3100 Electromechanical Lot System

Brand: UWT GmbH
Application Area

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.
Features
  • 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
