Paper break sensors - Sheet break detectors
Our paper break sensors (or sheet break detectors / web break detectors) were specially developed for harsh environmental conditions in paper machine and have been further optimized over many years:
Due to the fibre-optic concept, the sensors can be placed in more moderate areas, the high-performance sensors enable high pollution reserves, the robust fibre optic cables minimize light losses and are also optimally protected against mechanical stress!
And our new and innovative sensor concept for single-tier dryer sections distinguishes between paper and fabric on a material instead of colour basis and allow successful application right after the press!
Our sophisticated sensor systems enable reliable paper break detection (sheet or web break detection) in around 200 paper and board machines worldwide, even at high temperatures, moisture, pollution etc.!
Learn on the following pages about various products, which has been optimized for different application areas.
