Rotary paddle detector MBA801 Halfpipe

Level switch for bulk solids

Level switch with stepper motor technology

Thanks to the new MBA801 rotary paddle product series with halfpipe, the modern MBA level indicators with stepper motor technology can be used in even more bulk solids. The wing in the halfpipe is directed downwards by 90° and is therefore ideal for horizontal, i.e. lateral, installation in silos. This means that the new level switches can be used in positions where level measurement was previously not possible. As the shaft and vane under the roof are completely protected from falling bulk material, the MBA801 Halfpipe can also be used in the bulk stream: The falling bulk solids has no influence on the measurement.

Areas of application

The MBA801 Halfpipe level indicator offers maximum application versatility, regardless of bulk material properties.

The extra-strong shaft (12 mm shaft diameter) is mounted with the permanently welded-on paddle under a protective cover so that it is optimally protected from heavy or abrasive bulk material. The blade swivels 120° underneath the protective roof. The swivel prevents material from wrapping around the shaft or jamming the blade and indicating false alarms. If the bulk material in the silo rises and blocks the pivoting blade, an electrical signal is emitted.

The MBA801 Halfpipe can be used, for example

  • as a full detector, empty detector or demand detector in the silo
  • as a backwater detector in the downpipe
  • for measurement above discharge screws or similar conveyor systems
  • in transfer stations
  • below the discharge edge of conveyor belts
