MACHINERY | CONTROL & INSTRUMENTATION
Welex sheet extrusion lines – Navigator controls are now available for American Kuhne extrusion systems such as those for medical tubing, profiles and wire and cable. There are three levels of functionality: XC100 for stand-alone extruders; XC200 for one or more extruders in simultaneous operation; and XC300 for integrated production lines with the extruder and components such as a puller, water bath, or winder.
During the show, American Kuhne ran a tri-layer tubing line, comprising three compact modular extruders and the XC300 Navigator control with an integrated TwinCat Scope View data-acquisition system. Justin Kilgore, vice president of engineering at
Graham, added: “The ease and ability to integrate is boundless. From synchronised supervisory control of a line to internet for remote support and trouble-shooting, Navigator offers integration without limits.”
Length and speed NDC has developed a length and speed gauge for measuring the production of long, continuous cylindrical products. These types of products are not always well- guided and can move off-axis or out of the measurement range. This makes it difficult for traditional Laser Doppler Velocimetry (LDV) gauges to keep the laser on the product’s surface. This can result in hard-to-obtain or unreliable length and speed measurements. NDC says that the LaserSpeed Pro M series gauge – part of the Beta LaserMike product family – solves the problem. The patent-pending gauge uses a new type of LDV optical technique to provide reliable length and speed measurements of small, bouncing and unguided cylindrical moving products. This includes small plastic pipe, tube and hose, and other hard-to-measure cylindrical products. The gauge helps manufacturers control product

Contactless gauge Zumbach says that its GaugePro offers a fast, precise way to measure and record tubular samples in the laboratory. Conventional contact measuring equipment – such as calipers, micrometers and dial gauges – rely heavily on the skill of the person making the measurement. Different handling of the tools may result in significant variations in results. The new device can measure tubular samples in a contactless way. Using ultrasonic technology, dimensions such as wall thickness, inside diameter and outside diameter are measured instantly. In addition, ovality and eccentricity can be determined. An inserted sample is measured immediately at
four fixed measuring points. Due to the rotation function, the measurement can be extended to eight measuring points. This increases the coverage around the product and all variations in wall thickness become visible. Automatic self- calibration ensures that the measured values are accurately and reliably recorded even under changing environmental conditions. All measured values are displayed on a large user interface. Several measured tube samples can be summarised in a common statistic. Logging the measurement results is thus fast, easy and reliable.
