NextSense: Contact-free measurement of rail profiles

NextSense is presenting the Calipri contact-free measuring device for the error-free recording and rapid processing of the profiles of rails, switches and crossings. "Calipri satisfies the calls from the railway manufacturing industry for lowercost measuring solutions not needing time-consuming post-processing of the results" is how the manufacturer sums up Calipri’s benefits. The portable system makes it possible to perform measurements with a precision never attained before and thus furnishes clear-cut inputs for decisions regarding the maintenance of rails, switches and crossings.

Calipri can be used (in the same way as mechanical gauges) for inspecting the geometric data of standard-gauge railways and tram tracks. By way of contrast with other measuring techniques, this one produces results from which operator influences have been eliminated, thanks to the use of a contact-free method for recording the profile. As soon as the total profile line of the object measured has been recorded, the data is evaluated, the resulting measurements are shown on the display and the reports are generated. The versatile, precise and simple-to-operate optical measuring device can be used for individual inspections of rails, switches and crossings and also for the simultaneous measurement of the two rails making up a railway track, applying a common system of reference coordinates.
