Highly precise profile measurement for predictive maintenance

CALIPRI non-contact profile measurement devices meet the demands of the railway industry for predictive maintenance with a reproducible and simple measurement method. 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 gauges.

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, Fleet

"Calipri enables us to carry out a comprehensive analysis of the wheel wear on our fleets of vehicles." (translated)

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

S-Bahn Berlin GmbH, Germany, Service Team

"The customer service team at NEXTSENSE are highly skilled and always on hand to offer friendly advice and handy tips. It’s great that they don’t simply ignore users once they’ve bought the product." (translated)

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

LogServ, Austria

"The upgrade from CALIPRI C40 to C42 made our work much easier and faster. The wireless connection between the sensor and the tablet PC gave us a lot of freedom of movement. Data transfer is fast and smooth, so we're happy to recommend the upgrade.“

Gerald Bock
TECHNICAL TEAM, LOGISTIK SERVICE GMBH, AUSTRIA

BHP, Australia

“The ability to achieve efficient, repeatable, accurate measurements with traditional hand held equipment has been an ongoing challenge for us. In 2016, we purchased a number of the wireless sensor C42 Calipri units with wheel diameter gauges from Imtram, the local NEXTSENSE agent. The local and Austrian support provided is now a benchmark for us, ensuring a positive outcome for all of our specific requirements. Since implementing the Calipri equipment into the field, all identified issues have been addressed and we have not looked back.”
