CR100-PM

Fully automatic print mark detection

Fully automatic print mark detection

Automatic detection of print marks makes the CR100-PM an easy-to-use print mark sensor. Due to the perceptive color processing the sensor can recognize print marks with a low contrast to the background. Thanks to the adaptive control system the sensor can adjust its threshold to fluctuating contrast of the print marks. This ensures reliable detection also in applications with difficult ambient conditions. Its independence from ambient light and the integrated stabilization channel technology CROMLASTAB® ensure reliable operation during the whole life cycle.


Function

The functional principle of the CR100-PM is based on the three range procedure. The measuring light is assessed with the tristimulus value functions and assigned to the three wave length ranges red, green and blue. Through the assessment with these tristimulus value functions the sensor is able to perceive colors similar to the human eye.
The sensor contains an own white light source clocked with a frequency of up to 10 kHz. Sampling takes place in both, the light and the dark phase, so that the sensor is independent from ambient light.

The operation of the sensor is comfortable and easy. The user does not have to teach in color marks, as they are automatically recognized and stored by the sensor. After a start signal the sensor scans the background. Deviations are automatically recognized as marks. Corresponding to the number of output channels it is possible to teach in and display 4 different color marks automatically.
