Electronic Wheel Wear Caliper: WWC

FAST, DIGITAL, RELIABLE AND ACCURATE MEASUREMENTS

Electronic caliper for railway wheels. The device is designed to measure the parameters Sh, Sw, qR characterizing the wear of rolling stock wheels. Measurements can be performed directly on vehicles, i.e. without rolling the wheelsets out. The user can specify the limit values of the parameters as required. 

During measurements, the moving measuring tips touch the measured surface precisely at points specified by the railway regulations. Values of h, e1/e2, and qR parameters appear on the gauge panel display within two seconds after the initiation of the measurement and are clearly visible both in direct sunlight and in a dark inspection pit.

The gauge is equipped with a control panel with colour backlit display, and a comfortable keyboard. Measurement results and information about the exceedings of the limit values are clearly visible even in a dark inspection pit.

The gauge is delivered with PC software that allows for: archiving of measurement results, comparison of results, as well as printing of measurement reports. Measurement data can be exported to MS Word, MS Excel and PDF formats. The software delivered with the gauge also allows for collecting measurement results from all wheel measurement devices and generating aggregate reports.
