Voith introduced a new solution for web breaks in paper production identification

Wednesday, Jan 25, 2017

With WebDetect-nx, Voith has developed a new solution that identifies web breaks in paper production in a more reliable and fail-safe manner, as the company said in the press release received by Lesprom Network.

It is based on an innovative measuring process in which a multi-light sensor measures different light sources in the visible and infrared light frequency range and interprets the measurements simultaneously at high speed.

This prevents potential impairment of the measuring result to allow reliable detection of faults. This results in fewer false positives and therefore less production downtime as well as a lower risk of machine damage due to undetected breaks.

WebDetect-nx solves the typical problems associated with previous web break detectors based on infrared light and standard sensors. For example, if the contrast between paper web and dryer fabric or basis weight is too low or the moisture content of the paper too high, older methods tend to trigger false positives. This in turn leads to frequent production downtime or even damage to the paper machine.

The new solution from Voith prevents false positives due to a much more precise identification of web breaks. The greater accuracy is based on an innovative measuring principle, in which light beams of varying wavelengths are projected onto the web simultaneously.

Voith offers WebDetect-nx as a complete package; automation experts from Voith take care of system integration, engineering and documentation of all hardware and software components, and also commission the system.

Voith Paper is a corporate division of Voith and is one of the leading partners and pioneers in the paper industry.
