NivoBob® NB 3000

Electromechanical sensor for level measurement in solids and interface


The NivoBob® series of plumb bob sensors is used for continuous level measurement within bulk storage silos and for interface measurement. The simple electromechanical measurement principle is a truly reliable all-rounder in most bulk materials. The sensor weight, made of a suitable material, attached to either a tape or rope is electromechanically lowered from the top into the vessel. Once the sensor weight rests on the material, the winding direction of the motor changes and the sensor weight is rewound to the upper stop position. For interface measurements, the sensor weight can be adjusted according to the density of the sediment. The distance is electronically measured and together with the programmed silo geometry information the microprocessors convert this distance into a volumetric output signal. The NivoBob® generates an analog 4-20 mA signal and a Modbus RTU or Profibus DP interface for the evaluation systems.
