A color sensor usually has a light source as part of its system. The light source sheds light on a subject area, then the sensor detects and breaks down colors into components. These sensors are able to detect colors that are near the target color, or even exactly the same as the target color. Alternatively, some color sensors only detect the difference or similarity in color between the target color and other colors.
Applications include product seal, package and transparent product checking. Color sensors also work well for industrial sorting and quality checks, and also have many applications in laboratories. Various color light sensors operate differently:
1. A true color sensor bases on the colors red, green and blue (or occasionally on other color sets). Combinations of these colors make a great deal of the total light spectrum.
2. Some color sensors detect reflected light as wavelengths and then convert the wavelengths to output voltages. One advantage is that this type not only detects the colors visible to the human eye, but also ultraviolet (UV) and infrared (IR) light ranges.
3. Other sensors measure by contrasting between colors or shades.
Locate color sensors for sale for packaging processes and quality controlColor sensors can help you keep the outward appearance of your products consistent and appealing by checking package print as well as, for instance, consistency in beverage color. Secondly, when you use color sensors to check seal skirt or lining length and other seal quality checks, these sensors can play a role in making sure what's inside stays fresh.
Buy from product sorting color sensor suppliersA color light sensor can perform many types of sorting functions. One example is sorting batches of bricks that have slightly different shades.
Find color sensor distributors that carry highly-programmable devicesProgrammable color sensors have more versatility. Additionally, for scientific and complex industrial processes, sophistication is necessary.
- If you have some applications where you need to detect only one color and others where you need to detect multiple, you don't necessarily need two devices. Some programmable color sensors can perform both operations.
