We are the official UK supplier of the CALIPRI measuring device from NextSense. This handheld, non-contact laser scanner records all relevant wear parameters on Wheelsets and tracks quickly, comfortably and reliably.


Using three simple laser lines, this optoelectronic gauge records geometrical data for any complex shaped object. CALIPRI is more reliable than conventional measurement methods, as the distance and angle of the sensor do not affect the data collection process, eliminating human error and producing faultless, tamper-proof reports.


Complete measurement of each profile takes just seconds and requires only one operative, significantly increasing productivity. The data is then analysed and the results displayed on the handset. As a wide range of shapes can be recorded, the device is suitable for many applications, reducing purchasing, calibration and staff training costs.


The sensor is moved over the object to be measured by hand, whilst the intelligent image processing system records segments from various directions. Acoustic signals and a graphic display help the operator obtain quick and consistent results, even in confined and hard to reach spaces.


Your CALIPRI device can be tailored to the parameters you wish to record using the following modules:

  • Wheel profile
  • Tyre thickness
  • Wheel diameter
  • Wheel clearance (back to back)
  • Brake discs
  • Radial/axial runout
  • Wheel defects
  • Rail geometry
  • Switch – measurement of switch frogs and blades
  • Rail – a cross section of rail head/wear parameters
  • Analyser – a quick display of profile data
  • Equivalent Conicity Module

The ready-to-operate measurement system is installed with your software of choice and comes complete with sensor, connection cable, portable tablet PC and self-test/calibration device. A carrying strap and protective case are also supplied to minimise potential damage.
