Colour sensors

The colorSENSOR LT colour recognition sensors operate is connected to an optical fibre that is guided to the measurement target. Colour detection takes place very close to the object, which reduces any environmental effects. More than 2,000 different types of fibre optic cable are available to choose from, as well as a large number of lenses. True colour recognition is required in many industry sectors, enabling companies to select, monitor, grade and sort various types of coloured objects involved in manufacturing, automated handling, warehousing, packaging, wrapping and other production processes. Measured objects can take the form of solids or liquids and the user may also have a need to recognise the colours of transparent surfaces such as coatings or labels

The colorSENSOR LT range includes low cost, entry-level sensors through to high precision, multi-channel colour recognition systems. The range offers measuring distances from 2-100mm and up to 255 colour memory locations. As well as exact colour, these memory options enable the user to store specific tolerance limits for different applications. During colour recognition inspection, the sensor compares the colour it has been taught with the colour currently detected. The results are then made available via digital interfaces (RS232 or USB) as discrete values/numbers or NO/NOK statements. The sensors are supplied with their own set up and configuration software and a graphical user interface that enables the user to adjust the sensor to suit different applications.

Using new LED light sources, LT sensors can now be mounted much further away from the measurement target if required, at distances of up to 2,000mm.
