Special manually operated instruments with an electronic digital readout:
Model 4154

The model 4154 snap gauge is intended to be used for checking the diameter of hub contacting surfaces of railway vans’ axles.

The instrument provides also the possibility of checking the ovality and conicity of axle surfaces that shall be in contact with the hubs after assembly.

The results of measurements are represented on the visual display of the built-in electronic digital indicator MILLITAST 1082 made by the Mahr Company in Germany.

The setting-up of the snap gauge is carried out with the aid of a reference gauge (furnished with the instrument) by a single depression of the push button on the front panel of the electronic unit.

The application of the snap gauge is especially effective when it is used in combination with the ROBOCON model 4153 inside gauge for measuring the opening diameter of hubs that are to be assembled with the railway vans’ axles.

The instrument has been certified The Russian Federation State Standard Certificate No. 18579-99. Registration Certificate No. МТ 060.99 in the Branch of Industry Register of measuring means permitted to be used within the railway transport.
