NextSense, a company based in Graz, Austria, announced that it will unveil “the wheel diameter module for the Calipri high-tech measuring device” at the Innotrans 2010 railroad technology trade show in Berlin in September.
“The wheel diameter is one of the critical parameters involved in evaluating the running performance and safety level of railroad vehicles,” notes NextSense. “Until now, there have been no completely satisfactory solutions for measuring these diameters. The systems available on the market have either not been designed for mobile use or are too inaccurate. NextSense quite literally took up the challenge posed by these unsolved problems. After a two-year development phase, the solution is now available as a production-ready product for use in railroad workshops.
“A model manufactured using CFRP lightweight technology is fitted onto the built-in wheel with a hand grip. The user conducting the operation brings the sensor of the measuring device close to the model. After just a few seconds, the result is indicated and enables furthersubsequent evaluations to be carried out, such as the diameter difference on the wheel set or overstepping of thresholds,” NextSense says
NextSense says the new diameter-measuring device forms part of a family of measuring modules, which enable wheelsets to be measured while completely mobile.
