Non-contact optical measurement
The KB fiber optic sheet break detection system is designed to monitor sheet breaks in harsh environments. The proven non-contact sensor is placed above or under the web to be monitored.
KB is suitable for dirt, steam and high temperature installations or where space is limited. The air-purged sensor head stays clean and is not affected by dirt, steam or high temperatures.
RGB color and IR measurement
The KB has both RGB and Infrared light sources to perform superiorly with all paper and board grades and applications regardless of colors. The RGB color measurement can handle all sheet and felt colors providing reliable break detection. In addition to open-draw applications the breaks can be detected against felt, wire, or even against a cylinder.
Fast break detection and alarm
The KB's digital signal processing technology measures all signals thousand times per second. KB is immune to ambient light changes by measuring the backlight intensity. The break detection delay is minimum of 15ms - with digital filtration user can select how many measurement cycles are used for break alarm.
Easy to set up
The KB user interface allows easy setup of the break detection by selecting the measurements which give the highest signal difference. KB comes with color measurement PC software, which visually tells the color of the sheet / felt for the operator. Break and maintenance alarms are wired to the PLC or DCS. 4-20 mA current outputs for the signal levels are available as an option.
