CR50-FO

Compact color sensor with fixed optics

Perceptive color sensor with fixed optics and intuitive control concept

Due to its make as a color sensor with fixed optics the CROMLAVIEW® CR50-FO color sensor is very compact. The sensor recognizes finest color differences on all kinds of surfaces. The working distance lies in a range of 30 - 60 mm, depending on this distance the diameter of the measuring spot varies between 5 and 10 mm. The sensor can easily be programmed using the intuitive and simple button operation.

A mounting bracket is provided for the alignment of the sensor on the measuring object.


Function

The functional principle of the CR50-FO 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.
