W. Obendrauf et al., TEMPERATURE MEASURING IN PLASTICS PROCESSING WITH INFRARED RADIATION THERMOMETERS - THE INFLUENCE OF THE ABSORPTION-COEFFICIENT, International polymer processing, 13(1), 1998, pp. 71-77
In many areas of plastics processing the temperature is a decisive pro
cess control parameter. infrared sensors that detect the heat radiatio
n from molten plastic have a response time in the range of millisecond
s. Thus in many processes they offer the only possibility to measure t
ime dependent temperatures with high accuracy
