Colour sensor discriminates better than human eye
March 2006
Sensors & Transducers
The Wenglor colour sensor used to detect and sort coloured objects and liquids in the packaging, paper, printing, chemicals and food processing industries, can also be used for diverse applications such as high-speed, automated mail distribution to sort letters according to colour or in wastewater testing by means of colour temperature analysis.
The Wenglor colour sensor is unique due to its mode of operation. It detects the finest nuances, exceeding the limitations of the human eye. Even in the case of transparent objects, the slightest traces of colour are reliably recognised using a through-beam operating mode. With its integrated white light LED, the Wenglor colour sensor measures the colour components reflected by the object. The device continuously measures colour values, converts them to RGB colour values and compares with the values being used as a reference.
When a narrow discrimination window is selected, reliable differentiation is possible within a small deviation amongst minimal colour nuances - independent of ambient light. When a large window width has been selected, differentiation is only made amongst main colour groups.
The device operates in conjunction with Wenglor software, the RGB colour value read-out via RS232 interface and the reference colour adjustment is performed using an easy Teach-In process. The discrimination window width for colour recognition is individually adjusted in seven steps for each of the three primary colour (RGB) outputs. There is an adjustable on and off-delay.
