Universal Fault Detector UFD40 Roland Electronic GmbH has introduced the digital UFD40 system as a successor to its analogue UFD detector. The system has been designed to detect faults in butt welds and mechanical connections in wires, cables and small tubing made of metallic materials such as steel, stainless steel, copper, brass and aluminium. The UFD40 is based on the eddy current measurement principle; the material to be monitored passes through the orifice of an encircling coil sensor. Roland Electronic offers sensors suited for materials ranging in diameter from 1 to 90mm. The UFD40 has features typically available in classic eddy current fault detection systems designed for automated production processes. These include adjustable frequencies, high and low pass filters as well as y-component and vector analysis. The RS232 interface provides the con- nection to a host PC, which serves as the operating interface for the system and provides visualisation of all measurement values. Both measuring channels function autonomously, allow- ing the disconnection of the host PC. A parallel interface and fieldbus interface are available for communication with the production equipment PLC.

Partners in HV cable production With its X-RAY 8000 NXT measuring system Sikora provides a tool for quality control, production optimisation and reduced material consumption in power cable production. X-RAY 8000 NXT is the evolutionary successor of the X-RAY
8000 for measurement at CV-lines. X-RAY 8000 NXT is suitable for permanent quality control at the production of MV-, HV- and EHV-cables in CCV-, VCV- and MDCV-lines. Sikora is well known in the field of EHV-cable production. Specifically deve- loped for this application area Sikora offers the X-RAY 8000 NXT for the largest cable diameters from 180mm for CCV-lines and 220mm for VCV-lines. The X-RAY 8000 NXT measures the wall thickness, eccentricity, diameter and ovality with high measuring accuracy and repeatability. Only one scan is necessary to calculate all measuring values. X-RAY 8000 NXT allows the operator a fast centring of the extrusion tools, as well as optimum control of the production line in automatic mode. Multi-sensor semiconductor detectors are incorporated into the high-end variant of the X-RAY 8000 NXT. This multi-sensor technology
CSS 2 reliably detects contamination ❍ ❍ in the PE-insulation
Measuring wall thickness LaserLinc manufactures non-contact, precision measurement systems of OD and wall thickness for a range of industries, including wire and cable. The interface for the measurement hardware is LaserLinc’s own Windows-based measurement/data processing package, Total Vu Software ™ . Total Vu Software provides in-process tolerance checking, trending, SPC, feedback control, data logging, recipes and defect detection. These tools reduce scrap, save material, increase production efficiency, and improve quality. Options are available for monitoring other variables, such as pressures, temperatures, loads and speeds, to provide a complete view of the process, to identify problems early, and to facilitate improvements. LaserLinc systems are available in a variety of configurations and sizes, with laser scanners of one, two, and three axes, plus the new ultrasonic wall thickness measurement device, the UltraGauge+. LaserLinc scanners cover a wide range of product diameters, from 0.035um (0.0014") to 120mm (4.7").

Ceramic windows (patent pending) separate the scanners from the pressure of the CV-line. The surface of the ceramic windows does not react with any by-products resulting from the cross linking process and always remains clean. Together with reliable measuring systems, the cleanliness of the insulating material is an important requirement for compliance with quality criteria in the production of high voltage cables. Sikora offers an intelligent solution to recognise contamination in the PE-insulation before the cable is produced. Using the CSS 2 camera system from Sikora the total XLPE-material is examined for purity in the flow channel directly before the crosshead. The CSS 2 shows when production can start; it reports contamination and detects combustion particles, such as amber and scorches, in the material using a quantitative and graphical display.
