External measuring gauges

External measuring gauges are used for measuring the outer diameter of cylindrical parts (journals and grooves of shafts, axles, and bearing rings). Modern external measuring gauges are equipped with a portable electronic unit and self-generated power supply. The external gauge measurement results (in the form of diameter deviation from the initial value) are reflected in the digital form on the display of the portable electronic unit.
