CR50

Compact color sensor - intuitive controllable

Perceptive color sensor with intuitive control concept

The recognition of finest color differences on surfaces of all kinds is the strength of the CROMLAVIEW® CR50 color sensor. Due to an optical fiber connection the sensor can be adjusted to a large number of applications. Thus, the size of the measuring spot and the measuring distance are variable. Through a sophisticated control concept the sensor can be comfortably be parameterized via buttons. With a size of (50 × 50 × 21) mm3 the sensor that has been equipped with a powerful LED is very compact. The integrated stabilization channel technology CROMLASTAB® ensures reliable operation during the whole life cycle and protects it from temperature drift as well.


Function

The functional principle of the CR50 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 2 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.
