Highly precise profile measure­ments in the railway industry

CALIPRI non-contact profile measurement devices meet the demands of the railway industry with a reproducible and simple measurement method for the complete wheel-rail-system. Whether you are working with wheels, brakes, rails or switches – we have the right solution for any measurement task.

 

CALIPRI profile measuring devices are approved according to national and international standards (JCGM100: 2008, DIN V ENV 13005: 1999-06, DIN EN 13715: 2001-01, DIN EN 15313: 2016-09, DIN 27201-9: 2017-06), certified and used among others (e.g.) in Germany (DB), Austria (ÖBB), Switzerland (SBB), France (SNCF), China (Chengdu Railway Bureau) and the Czech Republic (SŽDC).

Applications

The multifunctional CALIPRI C4x series enables the combination of several inspection tasks (measurement modules) in one measurement device. For example, if you combine the modules for wheel profile, brake disk, wheel diameter and wheel clearance, you have a measurement device for evaluating a complete wheelset. CALIPRI Prime, on the other hand, focuses on wheel profile measurements and thus replaces conventional mechanical gages.

Customer voices

Learn more about the use of our CALIPRI systems by renowned rail companies in the areas of passenger and goods transport.

SBB AG, Switzerland, Quality

"Thanks to many years of fruitful collaboration with NEXTSENSE, we’ve been able to successfully integrate CALIPRI brake disc measurement into our everyday operations in accordance with SBB’s strict quality standards." (translated)

Matthias Grob
Systems Engineer for Brakes and Drives, SBB AG, Bern, Switzerland

SBB Passenger Transport, Switzerland, Digital

"Calipri combines a number of previously separate measurement devices into a single system. The idea of digital networking in vehicle maintenance has become a reality." (translated)

Daniel Meyer
Head of the Calipri measuring system, SBB Passenger Transport, Zürich, Switzerland

STADLER SERVICE, Switzerland, Prediction

"In the past, our client never used to be able to accurately estimate the maximum possible mileage of their wheel profiles when carrying out maintenance. But measuring with Calipri when performing maintenance on the Frauenfeld–Wil railway has finally made this possible." (translated)

Michael Vogt
SRS Wil Site Manager, Stadler Service AG, Wil, Switzerland

S-Bahn Berlin GmbH, Germany, Reliable

"The S-Bahn urban-suburban railway in Berlin has been using the CALIPRI C40 to measure wheels since 2010 – a total of twelve of them are employed in six plants to regularly inspect and monitor 5300 wheelsets. The CALIPRI devices successfully defy the harsh working conditions in the tough S-Bahn workshop and they’re extremely reliable as well. The process of ordering and delivering replacement parts as and when needed is very quick." (translated)

Frank Bartels
Vehicle Maintenance & Repair, S-Bahn Berlin GmbH, Berlin, Germany

STADLER SERVICE, Switzerland, Life time

"Calipri enables us to record and assess the mileage of the individual wheelsets and bogies, and then incorporate the projected mileages between the individual reprofilings into our maintenance and repair schedule. We can also show our client what condition the wheel profiles on their vehicles are in at any time." (translated)
