NEXTSENSE 2D profile measurement solution

Hexagon’s laser profilers offer a precise 2D profile measurement solution based on laser light
section technology. The technology captures profile curves with a laser and camera and is available
across a range of hardware and software options that offer advanced handheld and automated
measurement solutions to the rail industry.

The Hexagon Nextsense CALIPRI product series represents a range of handheld, non-contact profile measurement devices based on the patented Calipri principle, designed for rapid inspection of "Gap & Flush" and profile wear measurements that remain unaffected by operator experience. These devices are widely utilized in industrial settings and for profile dimension verification of molded materials. By replacing traditional mechanical gauges—such as calipers, templates, or even outdated impression methods—they provide digitized, traceable, and highly efficient data to drive process improvements.

- The system utilizes Calipri’s patented three-laser light section method, which automatically compensates for tilt and skew, ensuring that every measurement is precise and reliable regardless of the operator's technique.
- Regarding measurement specifications, the profile accuracy matches CAD profiles with a precision of 15µm and a nominal accuracy of 80µm, while maintaining a repeatability of ±35µm (±0.035mm).
- Measurement time is remarkably efficient, requiring only 3 to 10 seconds per item.
- Within a 10-meter range, the sensor can transmit and record data to a tablet via Wi-Fi.
- Furthermore, the software supports the import of DXF files, allowing for seamless comparison between standard profiles and real-world objects.

The application fields for this technology are extensive, including:
- railway track and wheel inspection;
- steel long product, roll pass, and hot rolling process inspection;
- as well as automotive manufacturing, where it is used to measure gaps, flatness, and design lines.
