Mobile Roundness Measuring Device

To prevent consequential damage to rolling stock and to increase the ride comfort of your guests, it is essential to regularly check the radial run-out of your rolling stock. With the mobile roundness measuring device OPTIMESS RN you can check the radial roundness and roughness as well as the axial run-out of the wheels in the shortest possible time.

OPTIMESS RN with tablet

The various parameters are automatically calculated and displayed on the tablet. The data can then be exported in various formats. Wireless communication between sensor and tablet allows optimal freedom of movement. One-button operation guarantees simple, intuitive user guidance. With the latest battery technology and sophisticated energy management, up to 300 measurements can be taken per charge.

Modern measuring software

Thanks to this mobility and the compact design, measurements in difficult spaces are also possible without any complications. The data is recorded and evaluated in the modern measuring software. This allows the simple and free configuration of an unlimited number of wheel and train types. The measured values are available directly after the measurement and are displayed in colour according to the previously defined tolerances, thus ensuring immediate control of the measured values.
