Maximum colour accuracy

Louise Smyth

Micro-Epsilon’s colour sensor range has been extended with the new CFO200 ColorSensor model, which with a measurement frequency of 20kHz, is ideally suited to dynamic measurement tasks.

220 lumen produces enormous light power. In addition, eight digital outputs are available. Due to the excellent repeatability of ∆E ≤ 0.3, the finest of colour graduations can be recognised reliably. Even dark colours such as black, grey and dark blue can be distinguished, e.g. when measuring the grey shades of concrete blocks and paving stones. In the automotive industry, the colour sensor determines the colour change during galvanisation to stop the machine when the set point value is achieved. The CFO200 is also used to distinguish materials and coatings, as the sensor also reliably recognises minor colour deviations, e.g. from stainless steel and zinc to brass and gold.

The high-precision CFO100 and CFO200 True Color sensors recognise any colour, whether it is for painting technology, automation systems, medical packaging, quality control, surface-labelling, and printing technology tasks.

The sensors can now be accessed using the innovative web interface from Micro-Epsilon that provides ease of use. Connected to a PC, the user benefits from graphic queries of sensor data and numerous convenient settings. Furthermore, the sensor can be adapted to suit different colour groups and tolerance spaces for each colour. Teach-in of colours can be carried out via web interface.

Recording colour values and control of the production systems is possible due to the Ethernet interface, which enables integration into modern industrial environments. Illumination and measurement are provided via an optical fibre that involves several advantages. The sensor is ideal for restricted areas as the sensor head requires a minimum of space. Furthermore, a large number of sensor heads fulfil the requirements of various measurement tasks and customer-specific adaptions.
