CR210E

Perceptive color processing with Ethernet connectivity

The color sensor processes colors in a perceptual way

The CROMLAVIEW® CR210E color sensor processes colors in a perceptual way (i.e. according to human perception) and assesses color distances with the precision of the human eye. For this purpose, a Lab color space is used in the color sensor, which has been equipped with a 4 Watt high power white light LED. Color distances are measured and assessed the same way humans would do. This sensor offers a maximum of flexibility, as it can be combined with a large number of optical fibers and focus optics by means of an optical fiber connection. On the other hand, multiple interfaces leave nothing to be desired. The color sensor, for example, can be connected with the computer via RS232 or USB interfaces. The freeware software CR-Tool, supplied with all CROMLAVIEW® color sensors, facilitates the parameterization and the visualization of color values. Besides that, the color sensor can also be operated using the buttons. More standard interfaces are 12 push-pull switching lines (24 V/100 mA per line), which, when binary encoded, can output 4096 switching states. As all the other CROMLAVIEW® color sensors, the CR210E is also equipped with the CROMLASTAB® technology, which protects it from temperature and age drift and thus ensures secure and reliable operation in the whole life cycle. For easy connections via longer distances the CR210E has been equipped with an Ethernet interface.


Function

The functional principle of the CR210E 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. Additive ambient light cannot change the difference between the light and dark phase, so that the sensor is independent from ambient light.
