Monitoring melt temperature

Ultratemp 6000 is Sikora’s latest development for the power cable sector. It is a non-contact polyethylene melt temperature measurement system, based on non-invasive ultrasonic tech- nology. It is specifically tailored to the production of medium voltage (MV) and high voltage (HV) XLPE insulated power cables. The system precisely measures the melt temperature during production without influencing the melt flow properties, as the ultrasonic sensors are positioned outside of the flow channel. Melt shear heating effects do not occur. Besides temperature measurement, the Ultratemp 6000 detects discontinuities in the melt. Early cross-linking after screens, which may lead to ambers and scorches in the polyethylene material, is avoided. The extremely high measuring rate allows a fast response time as well as the registration of small temperature variations. Ultratemp 6000 is described as an important step for further process optimisation and cost reduction during the production of MV and HV cables.
