Perceptive color sensor PCS-III

Dual channel color sensor for detecting colors like a human eye

Controls, handling and functionality of the PCS-III color sensor are very similar to those of PCS-I and PCS-II. The defining difference is the range of possible modes of operation.

In reference mode one color sensor input is used for getting a stable reference color (e.g. white). The second input is the working channel, directed at the objects that have to be tested. Reference mode allows for continuous color correction and thus ensures long-term stable color detection. This is why PCS-III color sensors are popular choices for situations in need of long-term color detection or color detection in environments with changing temperatures.

When configuring difference mode, color differences of the color impressions at both sensor inputs are detected. In this mode of operation, the color table contains color differences, not absolute color values. Difference mode is ideal for applications where color or contrast edges have to be detected for many different object colors.
