microducts in the diameter range of 3-20 mm. “The advantage of the X-Ray systems is that you

are confident about the measured values and you get correct product dimensions immediately with the start-up of the line with one shot,” said Toomas Koobas, CEO at Hoehle. “For microduct produc- tion, continuous inline monitoring is the key factor when talking about quality.” The company uses three separate monitors of the Ecocontrol 6000 processor system connected to each X-ray device. These give operators con- stant access to the current measurement values. Real-time visualisation is the secret of a perfect process control. Compared to alternative technologies, such as
ultrasound, X-ray technology provides consistent measurement without being affected by tempera- tures or material, he says. “With X-ray you get a measurement you trust and a guarantee of compliance with microduct specifications,” he said. The company also uses
Sikora lump detectors in its lines. These detect small non-conformities on the surface of the microducts. The operator receives immediate warning in the case of a fault and
can take necessary action. The combination of X-ray measuring systems and lump detection helps to raise product quality, says Koobas.
System upgrade Meanwhile, Zumbach Electronic has upgraded its Rayex S series of non-contact measuring gauges. The latest version is now available with embed- ded webserver access and native communication protocols such as OPC UA, Ethernet or Profinet. No additional processor or display units are required, it says. In addition, the series has a new mechanical design and improved algorithms for achieving better measuring results.
When combined with the company’s Usys IPC 2e
processor and display solutions and other measur- ing equipment – such as its laser diameter and ovality gauges – Rayex S is able to control entire production lines. Some key features and advantages include high stability and accuracy and sub-micron repeatability, says the company. The new models have a measur- ing frequency up to 20 Hz (in standard mode). Two X-ray sources are positioned at a 90° angle to one another, while an integrated exhaust device helps keep measuring windows clean. X-ray sources are robust and stable, with an expected lifetime of around four years.
Triangulating flaws The FlawSense dimensional surface flaw detection system from LaserLinc uses high-speed laser line triangulation to inspect products such as pipes and profiles. The company says it can detect lumps, gels, pits, slits and other surface defects – and perform the same functions as conventional laser micrometers, lump and neckdown detectors and camera-based systems.
