The operation
The MDD measures the wheel diameter using a three-point measurement. Two of the points being established by fixed rollers, the third point is measured with an induc-tive position transducer. The measured diameter can directly be read on the two displays, one on each side. The measuring result can be stored in the memory of the device, together with the running ordinal number and the date. An eight-digit ID number allows the identification of the loco, wagon or car and of the wheel.
The memory has capacity for 1800 measurements. The data transfer from the device to the PC is made through a cable to the serial or USB port. The data are received in ASCII format and can easily be integrated in Company’ s other programs.
