Automated wheelprofile measurement system (WPMS) for the rail industry
💫 A new chapter for 2026 💫
From January 1, 2026, we will operate as *Business Unit CALIPRI* within the Hexagon Group. NEXTSENSE GmbH will remain as the legal entity, without any external brand presence. Our brand presence becomes clearer and more consistent: Hexagon as the corporate brand and CALIPRI as the product brand.
CALIPRI will continue to stand for quality, precision, excellent service, and ease of use — and we look forward to shaping the future together.

Enables the transition from interval-based to condition-based and ultimately to predictive maintenance, reducing costs and improving resource planning.
CALIPRI X handles changing environmental conditions such as temperature, rain, or snow with ease. It delivers highly accurate results under all conditions, as confirmed by an independent testing institute.
CALIPRI X is designed for seamless operation over many years and is ready to measure without any startup time. The system is virtually maintenance-free, thanks to its lack of moving parts and integrated self-cleaning features.
The wayside monitoring system CALIPRI X automatically measures train wheelsets in seconds, on-track. Its precision, repeatability and integrated analytics minimise your rail maintenance workloads and lifecycle costs. It is easily installed on existing tracks to become part of your process. You automatically receive up-to-date wheelset metrics – with the proven precision and repeatability of CALIPRI technology.
Automated train wheelset measurement is productive, no question. But CALIPRI X’s measurement precision, availability and data handling puts it far ahead of traditional solutions. CALIPRI X is part of the CALIPRI family of non-contact measurement devices, trusted by rail operators like Germany’s DB, Switzerland’s SBB or France’s SNCF. CALIPRI X employs the patented CALIPRI Principle, helping it to acquire accurate, consistent measurement data from every vehicle. The balance of speed and accuracy is a genuine advance in automated in-track measurement system. Harness its efficiency and intelligence to drive substantial improvements in your maintenance performance and lifecycle costs. Together, CALIPRI X and CALIPRI Predictor offer an integrated solution that delivers unrivalled productivity gains and operational cost savings when maintaining your rolling stock over its lifecycle.
