The portable laser rail profilometer (PRP) is designed for the non contact registration of cross-sections of the railhead acting face.
The main functions of the PRP are:
- Obtaining information on the cross-section profile of the working railhead surface
- Full profile scanning and analysis of the railhead acting face
- Visualisation of the combined graphical images of actual and new cross-sections
An operator mounts the laser scanning module onto the railhead to be measured.
Having received a command from the PDA or PC, the laser module performs non-contact scanning of the rail surface. Measurement results (geometric parameters and profiles of the surface) are displayed on the PDA, can be saved in the PDA memory, and transferred to the PC database. Simultaneously, additional parameters can be saved, including date, operator number, permanent way division, track number, rail type, and more.
PRP Series
More photo PDA based handheld instruments are employed for laser scanning and the measurement of brake disk wear parameters. The devices are supplied with database and software packages for disk wear data storage and processing.
Railhead vertical wear: -5.0mm to +14.0mm
Lateral railhead wear: -5.0mm to +18.0mm
Reduced railhead wear: Up to 14.0mm
