The natural view of color sensing! Applications for Industrial Color Sensors Color Sensor Applications wf^^Mwith their color resolution of AE<1 the CROMLAVIEW" color sensors are reaching the application field of photo spectrometers. Thus, also applications in the automotive sector open up, which has very high demands on the sensors, as finest color nuances have to be distinguished. The color sensors CR100, CR200 and CR210 are finding their applications among car s manufacturers, but also particularly in the automotive g' supplier industry. The automotive manufacturers demand °| a zero-error-tolerance. Each part must be tested. With the s human eye, that is susceptible to fatigue, this is only 1 partially satisfactory possible. Various color checking tasks f arising, e.g. in the interior of cars, like for example: c Checking of the color of interior like door trim c Checking the color matching of assembly parts (Does speaker grill and door trim or radio buttons and control panels go together in color?) c Checking of carpet colors to match with target sample, c Coating of chrome parts (test of sputtering or vapor deposition processes) c Checking of correct seat of assembled parts based on the resulting color value c Differentiation of very small color differences of common colors in beige color tone and in black and gray color tones are needed to verify the correct interior color of a c Distinction of leather and imitation leather with same color, based on structural differences c Checking of the transmission properties of light conducting channels (e.g. lighting or display) c Checking of luminous objects (mostly LEDs) in displays ASTECH GmbH .

Applications for Color Sensors CR100 & CR200 testing of the correct or the same color and brightness appearance of luminous displays; color temperature or "color binning” of LEDs is checked. Outside the car, also many applications are found, such as the checking of the increasingly mounted LEDs. These are not only to be found in the rear part of a car, but also more and more installed in the front area. Furthermore, typical applications are checking the color matching of assembly pa r t s , s u c h as pa r k distance control sensor and bumper. This can be solved with the twochannel CR200 sensor...

For the application of the color difference mode in the CROMLAVIEW® CR200, the matching and the ganging of the two sensing channels are essential. Therefore the balance method CROMLABALANCE® is available. By this method, an easy and effective channel balance over the entire color space can be done. n One of the r e a l l y classic tasks of a c o l o r sensor includes the sorting tasks. By distinguishing colors, for...

Applications for Color Sensors CR100 & CR200 Online verification of printing processes saves time and money! Another field of application for the C R O M L AV I E W ® color sensors lies in the printing i n d u st r y. T h e t rad i t i o n a l approach of color management requires the complete know how of the printer with a high amount of time resources. Conventionally, in sheet offset printing sheets from the press were taken for quality control to Through an online color control be checked by hand spectrometers continuous monitoring of colors is or densitometers on color accuracy. possible....

Applications for Color Sensors CR100 & CR200 Color detection and color checking on coatings at the highest level Industrial coatings can be very diverse. Here are also applications where the focus is primarily on the color. For other applications, color is not important, but the presence of a coating material. In the pure color detection it often has to do with lacquering of sheet metal, plastics and other parts. For example, for the production of so-called "white goods" (refrigerators, stoves, washing machines) aluminum sheets with the w h i te t o n e o f t h e a p p l i a n c e manufacturer...

Applications for Color Sensors CR100 & CR200 CHEMISTRY In the chemical industry, many color applications deal with t h e d e te c t i o n o f liquids in which we find two basic methods. With transparent liquids, it is basically necessary to irradiate them. However, with increasing absorptivity of the medium the emitted radiation power decreases, so it is no longer possible to irradiate the medium. In this case, one should work in the reflection mode, in which the reflection of the medium is measured. This procedure is unfortunately not as distanceindependent as the through beam method. In the...

Applications for Color Sensors CR100 & CR200 increasingly important. Many manufacturing companies introduce their waste water into rivers. The verification of the functioning of the filters is more challenged than ever. For the own protection a complete record of the wastewater streams is useful. If the contamination is indicated by a color change, detection with a color sensor is possible immediately. One example is a hydrometallurgical process in which copper is extracted. The waste water should be crystal clear. However, if the iron content is too high, which is indicated by a very light red...

Applications for Color Sensors CR100 & CR200 FOOD Food has to be a feast for the eyes, too! As in many areas of industry the focus in the food industry is not only on the core features of a product, actually by specific design of outlying properties one attempts to achieve competitive advantage. An example for this is the sound design for the sound while bite into a biscuit. Similarly, color also plays an important role, as already suggested by the above proverb, because the visual impression (even before the taste) is the first impression that a customer will get of a food. And the first impressions...
