Brake Disc Measurement
BRAKE DISC PROFILE MEASURING WITHOUT CONTACT
Carry out highly precise measurements and evaluations of different brake disc types.
Technology – COMPLETE WEAR PROFILES WITH NON-CONTACT MEASUREMENT TECHNOLOGY.
The “Brake Disc” CALIPRI C42 measurement module carries out non-contact evaluations of brake discs. Due to the laser light section technology, the compact measurement device is aligned with the brake disk without mechanical mounting. The sensor records the complete wear profile and clearly displays both actual and target values on the sensor and the tablet PC. In addition to essential measured variables, such as brake disc hollow tread and thickness, the system also measures wear stock and rippling in a matter of seconds. In this way, you can, for example, identify diagonal wear tendencies and take the appropriate precautions.
Advantages – QUICK MEASUREMENTS OF CRITICAL WEAR VALUES.

Thanks to the non-contact measurement technology, you now only need one measurement device to evaluate all common brake discs. This reduces acquisition costs and saves time during servicing. It also eliminates the need to laboriously apply individual templates or imprecise sliding gages. Even worn or dirty reference edges do not present a challenge. Measured data can be transferred digitally to eliminate possible errors in handwritten reports. The measurement device is designed as a modular system and measurement modules, such as the wheel profile measurement module, can be added.
Calipri is approved and uses i.a. in Germany (DB), Austria (ÖBB), Switzerland (SBB), France (SNCF), China (Chengdu Railway Bureau) and the Czech Republic (SŽDC).

Lightweight CFRP gage makes it possibly to easily and precisely
measure wheel clearance, track and reference dimensions.
Technology – DIGITAL MEASUREMENTS WITH LIGHTWEIGHT AUXILIARY GAUGE
The “Back-to-Back” CALIPRI C42 module uses an optical measuring system and a carbon fiber reinforced polymer gage to measure track and standard dimensions and wheel clearance. In order to carry out the measurement, simply clamp the auxiliary gage between the wheels of one axle. Then use the CALIPRI sensor to measure at two measurement rings on the gage. The system automatically calculates the wheel clearance and compares it with the predefined limit values. The results are shown on the sensor display and are also available on the tablet PC for generating reports or a subsequent data export.
Advantages – MEASURE WHEEL CLEARANCE, TRACK AND STANDARD DIMENSIONS SIMULTANEOUSLY
- Automatic limit value comparison
- Lightweight auxiliary gage
- Multifunctional measurement device

Manually calculating and comparing measured values to a limit value table is a thing of the past. Actual values are measured digitally and deviations from target values are highlighted in color on the tablet PC. Unlike conventional wheel clearance measurement devices, the CALIPRI auxiliary gage is lightweight and can be easily clamped between the wheels. The system can be used directly under the vehicle or on a wheelset which has been removed. The modular software concept makes it possible to combine wheel profile and wheel clearance measurements so that the track dimension can be evaluated automatically.
Calipri is approved and used i.a. in Germany (DB), Austria (ÖBB), Switzerland (SBB), France (SNCF), China (Chengdu Railway Bureau) and the Czech Republic (SŽDC). This measuring module has been successfully tested according to JCGM100: 2008, DIN V ENV 13005: 1999-06, DIN EN 13715: 2001-01, DIN EN 15313: 2016-09 and DIN 27201-9: 2017-06.

The CALIPRI measurement module “Track Geometry” evaluates track gauge, superelevation and rail cant. Furthermore, it directly calculates the twist in order to detect irregularities on site and to initiate the necessary maintenance tasks directly. In combination with the Calipri measurement modules “Rail” and “Equivalent Conicity”, the user receives information on track geometry, rail wear and equivalent conicity values with only two measurements.
Advantages – EASY TRACK GEOMETRY MEASUREMENT
- Single gauge positioning
- Direct calculation of twist
- Additional measurement modules available (e.g. rail profile)
- Direct data transfer via WLAN
- Flexible interfaces for data export
- Low weight
- Patented CALIPRI measurement principle
The measurement is carried out with the non-contact Calipri sensor using advanced laser light section technology and a handy GRP lightweight supporting gage. For this purpose, the gage is placed on the track and aligned at an angle of 90°. This enables the sensor to measure the rail profiles without having to turn the gage. The patented Calipri measuring principle allows not only the recording of the rail head, but also the entire rail cross section. The measured parameters are displayed on the tablet PC and on the sensor itself and can be compared with reference values. A traffic light system is used to make limit violations easily identifiable. After the measuring process, the operator can decide directly, whether measures must be taken in order to correct the track.
