The "Back-to-Back" CALIPRI C4X module uses an optical measuring system and a carbon fiber reinforced polymer gage to measure track and standard dimensions and wheel clearance. In order to carry out the measurement, simply clamp the auxiliary gage between the wheels of one axle. Then use the CALIPRI sensor to measure at two measurement rings on the gage. The system automatically calculates the wheel clearance and compares it with the predefined limit values. The results are shown on the sensor display and are also available on the tablet PC for generating reports or a subsequent data export.
Manually calculating and comparing measured values to a limit value table is a thing of the past. Actual values are measured digitally and deviations from target values are highlighted in color on the tablet PC. Unlike conventional wheel clearance measurement devices, the CALIPRI auxiliary gage is lightweight and can be easily clamped between the wheels. The system can be used directly under the vehicle or on a wheelset which has been removed. The modular software concept makes it possible to combine wheel profile and wheel clearance measurements so that the track dimension can be evaluated automatically.
Calipri is approved and used i.a. in Germany (DB), Austria (ÖBB), Switzerland (SBB), France (SNCF), China (Chengdu Railway Bureau) and the Czech Republic (SŽDC). This measuring module has been successfully tested according to JCGM100: 2008, DIN V ENV 13005: 1999-06, DIN EN 13715: 2001-01, DIN EN 15313: 2016-09 and DIN 27201-9: 2017-06.
