25 Apr. 2022. ABB is launching their new KPM KB2 Ranger Model, a sheet break detection device that is invulnerable to paper jams, color and grade changes for the highest uptime with the lowest required maintenance.
As the latest addition to ABB’s industry-leading KPM Sheet Break Detector portfolio, this non-contact optical sensor will prove particularly important for paper or board producers making frequent grade changes or colored papers. The single, one-button calibration removes the need for complicated, grade-specific settings, while the RGB break profiling method reduces false positives and automatically updates for more robust detection over time.
The KPM KB2 Ranger model offers a longer measurement distance – up to 1.5 meters – and side installation to keep the sensor head outside the machine. It can provide reliable break detection in all configurations, such as against felt, wire or cylinders, and its freely adjustable sensor head is able to detect breaks from any angle. This removes the possibility of paper getting stuck on the sensor head, enabling higher reliability and accuracy across all paper and board grades, regardless of color.
While the sensor head can withstand high temperatures, the electronics unit is mounted outside the machine hood using fiber optic cables, preventing the electronics from being affected by dirt, steam or temperature and maintaining high reliability even in a high humidity environment.
Unlike comparable solutions that require in-machine installation, ABB’s KPM KB2 Ranger model augments the current offering to deliver higher uptime and reduced unplanned downtime. It requires minimal, if any, maintenance and cleaning due to its air-purged sensor that keeps the unit clean for continuous and trouble-free operation.
“Our KPM Sheet Break Detector is recognized as the best on the market and the proven choice for installations in harsh environments or where space is limited,” said Karin Hermansson, Product Line Manager, ABB. “We are pleased to unveil the new KB2 Ranger Model to offer additional options for mills facing frequent grade changes or color-related issues, while proving our commitment to continual innovation surrounding mill optimization solutions.”
KB2 is applicable globally across paper, tissue, board and pulp machines, and can be used on press or drying sections.
