ULTRATEMP 6000

Ultra-productive with ultrasonic

Ultrasonic temperature measurement system for polyethylene melts

With the new ULTRATEMP 6000* SIKORA is presenting an ultra-reliable temperature measurement device based on ultrasonic technology, which is specifically designed for the measurement of PE melts. During the production of polyethylene hoses and tubes the melt temperature plays a critical role. It can affect the quality of the product as well as the productivity of the extrusion process. With polyethylene materials organic peroxides are used for cross-linking. Here, the melt temperature is subject to tight tolerances, since proper melting and homogeneity set the lower limit while avoiding premature cross-linking sets the upper one.

Innovative technology for a new level of quality and productivity

Until now, conventional methods are used to measure the melt temperature such as contact thermocouple sensors. More often even simple hand-held meters are utilized to measure the melt temperature after the cross-head before starting up the extrusion line. These techniques do not offer reliable measuring results as they are contact measurements with a relative slow response time. Moreover, they can influence the melt flow properties which may result in cross-linking.

SIKORA's ULTRATEMP 6000* is a non-contact melt temperature measurement system based on non-invasive ultrasonic technology. It precisely measures the melt temperature during production and does not influence the melt flow properties. With the use of ULTRATEMP 6000* melt shear heating errors are eliminated. It ensures homogeneous melt viscosity for the extrusion process and helps to avoid premature cross-linking after screens, which may lead to ambers and scorches in the polyethylene material. SIKORA's temperature measurement system optimizes the running time and the productivity of the extrusion line.
