Further operational areas are possible for this basic technology.

  • Contact-less speed measurement of weft
  • Contact-less measurement of electrostatic charging of thread after a preparation of material
  • Contact-less measurement with high and low speeds
  • In perspective: Speed measurement of surfaces

Results are also available for related subjects to be integrated into further research.

  • Measurement of electric thread charge.

Ideas are always welcome. Please contact us at We would like to point out that our technology is applicable on other (non-conductive) materials also (e.g. paper, plastic, fibers) offering more operational areas.

You can find further information on the research page at University of Chemnitz.


The contact-less thread sensor is the result of a long-term research. Foundations have been layed down by Prof. Dr. Peter Offermann during a project of the German Research Foundation (DFG) at the Institute of Textile Machinery and High Performance Material Technology of the University of Dresden, Germany.


Results have been published in different journals, e.g. Melliand Textilberichte 84 (2003) H. 5, S. 415 ff.


Basic principle is the analysis of electric charges distributed in the thread randomly. These charges are transformed into impuls using a powerful signal processing where one impuls is equal to 4mm thread length.
