When moving the track in the plan in the plan, the wheelset also moves. The signal from sensor 1 after separation of its useful component by filter 3 and double integration by integrator 4, proportional to the movement of the wheel set in the plan, goes to the inputs of the adders 5 and 6. The other inputs of the adders 5 and 6 receive signals from the proximity sensors 8 and 9 of the heads the rails in terms of the wheelset within the gaps between the flanges of the wheelset and the side (inner) faces of the rail heads. After receiving the difference of the signals at the inputs of the adders 5 and 6, the signals at the data outputs of the total 10

The outputs of the adders 5 and 6 through the matching elements 10 and 11 are connected to the recorder 12. The outputs of the adders 5 and 6 are also connected to the inputs of the adder 13 and the comparator 14, the output of which is connected to the recorder 12, the output of the adder 13 through the matching element 15 connected to the recorder 12. Matching elements 10, 11, and 15 are analog-to-digital converters. In the case of using a recorder recorder with analog recording of signals, these elements are amplifiers. There is also a distance sensor 16 connected to the recorder 32 .

In addition, the device contains a template 17, which can be used as a lowered trolley or a removable gauge for measuring the gauge, having a sliding axis associated with a linear displacement sensor (potentiometer, rotating transformer).

The rails in the plan and through the matching elements 10 and 11 are fed to the recorder 12. The signals from the outputs of the adders 5 and b also go to the inputs of the adder 13, from the output of which, in the form of their difference, representing a signal for changing the gauge, the signal goes through the matching element 15 to one of the inputs of the recorder 12. The use of the comparator 14 in this system is necessary for those cases when the signals from the adders 5 and 6 are equal, i.e. there is a constant gauge width, which corresponds to a zero signal at the output of the adder 13. 35 In case of equality of signals from the adders 5 and 6 from the output of the comparator 14, the recorder 12 receives a signal on which the gauge of the gauge is recorded before the beginning of its constancy. The template 17 ensures that the recorder 12 is set to the gauge position before the car starts moving, after which the template is turned off. From the sensor 16 traveled path to the recorder 12 receives information about the traveled path.
