CR100-FO

Compact color sensor with fixed optics

Industrial Color Sensors with the precision of the human eye

Due to its design as a sensor with fixed optic the CROMLAVIEW^® CR100-FO color sensor is even more compact the well-known CR100. It 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 measuring spot diameter varies between 5 and 10 mm. There are two methods to put the color sensor into operation, via buttons on the sensor, but also by using the free delivered software CR-tool for parameterization.

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

Function

The functional principle of the CR100-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 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.
