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.
"Errors in break detection often cause unnecessary interruptions in paper production and can even lead to machine damage – in either case these downtimes cost paper manufacturers time and money," says Peter Biener, Product Manager at Voith. "WebDetect-nx allows much more accurate and therefore more reliable detection. It also simplifies operation and maintenance of the system thanks to the digital interfaces. As a result, paper manufacturers can achieve higher and more efficient paper production."

WebDetect-nx features interfaces like Profibus, Modbus-TCP or Standard I/O for simple access via the process control system, on which measuring processes can be visualized and the break sensors controlled interactively. Using programmable logic controller (PLC) function modules, the WebDetect-nx from Voith can be easily integrated into the Machine Control System (MCS) and therefore operated fully automatically. The technology is one of Voith's innovations from its Papermaking 4.0 concept that allows papermakers to take a significant step towards the Smart Factory. During startup, customers can also set specific parameters conveniently via the system's user interface. A suitable interface is also available for this process. Only the sensor measuring head requires mechanical adjustment.
WebDetect-nx also features an improved purging air system, which ensures that the sensor optics stay clean longer and rarely need maintenance. Moreover, the diagnostics system automatically notifies the need for maintenance and thus ensures more efficient servicing intervals.
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.
