Colour Measurement System CM2
The CM2 system serves the automatic colour measurement of plastic granules. The granules are carried in a special measuring channel.
In the process it develops a granule column, which can be brought to the optimal measuring temperature through an air flush. In the measuring channel there is an opening which serves the measurement.
A rotary feeder (optional) provides a continuous transport of the granules. A colour spectrometer records the colour spectrum of the granules through the instrumentation opening and generates the colour of the granules.
Different colour displays or standards can be realised e.g. L,a,b or X,Y,Z etc. Yellowness Index
The data can be rounded up and assigned to a process control system.
