The rotary paddle level indicator DF22 is used in most bulk solids for full-, empty or demand-detection within silos and bins. The individual sensor configuration with a large number of options and a lot of accessories enables an accurate adaptation to any specific application.

 

Product Features

  • ideal for silos with caking at the inner wall due to extended process connection up to 200 mm maximum length
  • unaffected by pressure, temperature, dust, caking, and conductivity of material
  • to be used in areas with potentially explosive dust atmospheres as well
  • versatile and universally applicable
  • fantastic price-performance-ratio
  • high reliability
  • continuous operation without maintenance
  • easy installation

Technical Data

The DF22 is a level limit switch with extended process connection for bulk goods such as powder, granulate, fine and coarse-grained. In different applications these DF22 indicates minimal or maximal fill levels reliably and precisely. Therefore it is used in many different industries:

 

Applications

Our level control indicators are named in business magazins as paddle switches, rotary paddel switches, point measurement devices, level sensor, level switch or level control.
