Railway Wheel Profile Gauge

The laser profilometer is employed for measuring geometrical parameters of the rail wheel flange (thickness, slope, height), rim/tire thickness and for taking full profile of the wheel roll surface.

The device is supplied with database and software package for wheel sets wear data storage and processing.

Operator mounts the laser scanning module onto the wheel to be measured. Having received a command from PDA or PC, the laser module performs non-contact scanning of the wheel surface.

Measurement results (geometric parameters and profile of the surface) are displayed on PDA, can be saved in the PDA memory, and transferred to the PC database. Simultaneously, additional parameters can be saved: operator number, side identifier(left or right wheel), axisnumber, locomotive (carriage) number, wheel pair number, etc.
