CALIPRI Prime is fully-integrated optical inspection system for the precise measurement of the key railway wheel profile dimensions within a few seconds.

With CALIPRI Prime, errors caused when attaching bulky instruments and variations from using wheel profile wear gauges or templates are a thing of the past. CALIPRI Prime uses laser light section technology, so a camera/laser unit in the measurement device records the wheel profile without having to manually attach it to the wheel. The device’s embedded software evaluates all relevant dimensional parameters according to preset limit values. All the wheel characteristics are displayed on the sensor screen within a few seconds and are available for digital transfer to your PC if needed. Additional functions, such as colour highlighting of out-of-tolerance areas or profile export are optionally available.

The CALIPRI Prime is typically used in for train wheel measurement in maintenance applications in service shops, stations or in the field. It can replace mechanical gauges and fixtures, reducing overall costs and improving accuracy.
