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.

TESTIMONIALS

Customer voices

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

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

SBB AG, Switzerland, Partner

"The requirements we impose on brake disc measurement are stringent and specific – but we have found the perfect partner to satisfy them in NEXTSENSE. The fact that we have been working together for many years means we are now able to measure the brake discs on our fleets with complete repeat accuracy." (translated)

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

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

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.”
