ABB KPM Sheet Break Detector - KB2

ABB KPM Sheet Break Detector - KB2 

Product overview

KPM KB2 is a non-contact paper breakage detector launched by ABB, with hundreds of installation cases worldwide, recognized as an excellent paper breakage detection device in the market. It can be installed above or below the paper web, suitable for environments with high dust, steam, high temperature, and limited space. It keeps the sensor head clean through air blowing and can reliably monitor paper breakage in harsh environments.

Core functions and features

Flexible detection light source: equipped with RGB or infrared light sources, it can perform well in various paper and cardboard products and applications regardless of the color of the paper and cardboard. RGB color measurement can handle all paper, mesh, and woolen colors, ensuring reliable fracture detection. In addition to open traction applications, it can also detect fractures in woolen, mesh, and even drum backgrounds.

Fast fracture detection: Using digital signal processing technology, thousands of measurements are taken of all signals per second, and the backlight intensity is measured to resist the influence of environmental light changes. The minimum delay for fracture detection is only 15ms, and users can select the number of measurement cycles for fracture alarm through digital filtering.

Convenient setup and operation: Equipped with a large display screen and a logical user interface, the fracture detection setup can be easily completed by selecting the measurement value with the largest signal difference. The fracture and maintenance alarm can be connected to PLC or DCS, and color measurement PC software can also be selected for monitoring, including data collection function.

Adapt to harsh environments: It can maintain high reliability even in high humidity environments. When the sensor head is exposed to high temperatures, the electronic unit can be installed outside the machine cover through fiber optic cables.
