Track measurement

The X-Y Switch Profile Measurement Gauge is used for measurement of the transverse sections of switch elements in the characteristic points of frogs and half of a pair of switches. The gauge is based on the track during the measurement cycle, using the special beam as the datum. Having located the gauge in the required position, the operator guides manually the spherical measuring tip along the inspected surface and its trajectory is stored in the electronic memory that is large enough to store 30,000 measured profiles.

The X-Y gauge makes it possible to measure virtually any switch element in the following measuring range: X axis = 575 mm; Y axis = 110 mm with the accuracy of ±0.1 mm in each axis.

The gauge has many advantageous operational features. Its low weight (ca. 7 kg) and magnetic fixing to the track or switch elements make its quick removal from the track possible to let the train pass.

The device may be used for planning the maintenance scope of switches; it is possible to work out its detailed documentation and the graphical representation of each switch wear, as well as introduction of this information to the tender documents. Results of measurements carried out with the gauge may be used for commissioning the scope and quality of repairs done by the service providers - one can illustrate the condition before and after repair with the reference profile in the background. Moreover, a possibility of presenting many profiles measured in the same transverse section of the switch during its operation makes it possible to follow its wear out developing in time.

The PC software supplied with the gauge makes it possible to create the theoretical profiles for each cross sections of the switch elements, comparing the measured profiles with the theoretical ones, and comparing the profiles measured at different times. Graphical software provide features like adding dimensioning to the drawings, annotations, zooming, and many other. Measurement data upload to the PC is possible using the USB PenDrive; measured profiles may be exported as files in TXT and DXF formats.
