Calipri Wheelset measurement system

Aquafrisch is the official supplier for Spain of Calipri developed by Nextsense.

AQUAFRISCH is the official supplier for Spain of Calipri, developed by Nextsense. Calipri’s laser technology makes it possible to measure rolling parameters in a few seconds and in an agile and precise way, even in the most difficult places with reduced space under the vehicle.

Using Calipri, human error in measuring and exporting results is reduced, thanks to the fact that Calipri corrects the inclination of the sensor in real time and records the results in a file compatible with spreadsheets. With Calipri it is possible to create personalised measurement plans, identifying vehicles, operators and parameters to be measured. Measurement modules currently available: This innovative method of measurement allows to integrate in the same equipment the measurement of multiple parameters, with immediate results.

This feature makes the scope of supply scalable. Thus, each parameter to be measured corresponds to a module, allowing the customer to choose the modules to be supplied with the acquisition of the equipment and which are to be supplied later.

 For rolling stock, the modules are:

Wheel profile

Wear on brake discs

Distance between internal face

Rim Thickness

Wheel diameter

Equivalent taper

Wheel defects

Ovalization

Calipri offers solutions not only for rolling stock, but also for infrastructure:

Profile of rail

Rail Defects

Needle changes

Geometry and relative positions of the rails

Sensor

The standard C42 sensor is wireless. For confined spaces, we offer the C41 wired sensor. For exclusive measurement of the tab, you can purchase Calipri Prime.
