Generators and Converters

Frequency Variation Generators

Frequency variation generators provide working frequencies in the range of 30 - 38 kHz, and they are perfectly suited to excite complex mechanical structures. The system automatically searches for the optimum working point. The frequency variation using the frequency bandwidth mentioned above does not require any individual adjustment to the mechanics (“Plug and play” concept).

Other features:

  • Different power settings for excitation of diverse screen surfaces
  • Simultaneous excitation of screens with a generator is possible
  • Developed for operation in harsh and damp environments
  • An external PC can be used for all operating functions and parameter settings
  • Digital inputs and outputs
  • Digital error coding
  • Frequency analysis of the acoustic system is possible
  • available as ATEX version for explosion harzadous areas EX II3D EX3D tc T80° DC 

Converter

The converters are developed for the excitation of mechanical structures of various shapes and sizes. 

The installation (incl. HF cable) is situated outside the powder flow and screen body, which eliminates material caking.
