Safety is paramount in rail. Regular wheelset measurements are therefore especially important to meet stringent regulations and to guarantee passengers a safe and smooth journey.
These regulations and requirements bring challenges for the customer and operator in their daily business:
CALIPRI measuring devices from Hexagon | NEXTSENSE can make a significant contribution to supporting the maintenance flow.
Both the handheld CALIPRI C42 measuring system and the fully automated on-track wheelset measurement system, CALIPRI X, ensure that the measurement results are in accordance with the relevant standards. These standards require reliable, highly available and precise measurement data.
The multifunctional CALIPRI C4x series enables the combination of several measurement modules in one measurement device. If, for example, the modules for wheel profile, brake disc, wheel diameter and back-to-back are combined, the result is a measuring device for evaluating a complete wheelset. CALIPRI Prime, on the other hand, focuses on wheel profile measurement and thus replaces conventional mechanical gauges.
The measurement process is based on laser light section technology. The user guides the sensor over the measurement object by hand. It is not necessary to precisely maintain the distance and angle of the sensor.
