The electronic gauge is designed for measuring wheel rolling circle diameters. Measurements are made directly on the rolling stock, without wheel set roll-out. The measurement of the diameter is performed according to the ‘three points’ technique, without the complete wheel coverage. The gauge contains a numeric display to show the value of the wheel diameter. The IDK-BT gauge contains a Bluetooth interface to transfer results into a wheel-set wear database management system.
The measurement method is based on the diameter calculation using the known length of the segment chord (the distance between the ball bearings centres), which is obtained when placing the gauge onto the wheel. The suggita of the segment is measured using the displacement converter.
