The rotary paddle level indicator DF30 is used in most bulk solids for full-, or empty-detection mainly within the discharge taper of loading bellows. 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

  • short installation height due to reduced length of process connection with 100 mm minimum including measuring blade
  • short reaction time due to faster rotating speed of the motor
  • unaffected by pressure, temperature, dust, caking, and conductivity of material
  • to be used in all areas with potentially explosive atmospheres as well
  • versatile and universally applicable
  • fantastic price-performance-ratio
  • high reliability
  • continuous operation without maintenance
  • easy installation

Technical data

The DF30 is a level limit switch with a very short process connection for bulk goods such as powder, granulate, fine and coarse-grained. These DF30 that is typically installed in loading bellows reliably and precisely gives a signal as soon as the truck is fully loaded. 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.
