System for continuous on-line color monitoring for coarse and fine grained products, powders, pastes and liquids.
The decisive advantages:
Contactless measurement
Excellent reproducibility of the measurement results
Printer and logger output as a standard feature
No interference from outside light sources
adjustable sensitivity and reference point
option of graphic display and recording as well as process control functions
Mode of operation:
The COLORCONTROL measuring head contains an opto-transmitter, a photo-detector and an evaluation electronic module. The product is moved under and past the measuring head and is illuminated by monochromatic laser light. The share of this light reflected by the product is detected and electronically evaluated. Uneven product surfaces are compensated by ave raging. Different surface gloss of the product is largely suppressed by optical measures. The measured value is indicated on a digital display and is also output as both an analogue and a digital value for further processing. The constant stream of measured values can be recorded with the aid of a continuousline recorder or a printer.
