Zulkigul For example, the edition of Mr. There is a hierarchy of physical measurement standards. No additional import charges at delivery! The spring elbow, in turn, is connected to a plunger, which moves upwards or downwards. One advantage of elimination of artifact standards is that inter-comparison of artifacts is no longer required, another advantage would be that the loss or damage of the artifact standards would not disrupt the system of measures.

Take a look at the Johansson Mikrokator Diagram….. The twisted strip is tightly held between cantilever strip and bell crank lever. At the middle of the strip, there is a light pointer is held, to magnified by this twisted strip to show the measurement. The Bell crank lever will be connected to the plunger Spindle You can see it in the above Picture A small vertical movement in the plunger will result in the rotational moment in the bell crank lever. Thus rotation movement in Bell crank lever will ensure the change of length of the Twisted strip.

The change in the length of the strip will show as the measurement with the help of light pointer which is fixed at the middle. When there is no workpiece underneath the plunger, or workpiece is removed, then the plunger will get its original position by the spring action in the twisted strip.

The magnification can be adjusted by adjusting the Cantilever strip length. How to use Johansson Mikrokator? The comparator is for comparing the dimensions right? A working standard will be placed underneath the plunger to take the dimension as the required dimension.

This could be Slip Gauges. Take the readings and remove the actual working standard Slip Gauges Now place the workpiece underneath the plunger to take the measurement of the workpiece. Compare the reading with the Actual working standard reading.

Construction[ edit ] Johansson mikrokator A metallic strip is twisted and fixed between two ends as shown. Any longitudinal movement in either direction will cause the central portion of the strip to rotate. One end of the strip is fixed to an adjustable cantilever and the other end is fixed to the spring elbow. The spring elbow, in turn, is connected to a plunger, which moves upwards or downwards.
