This is a mechanical comparator providing magnification in 300 to5000.It can vary by changing the length of the strip with screws provided on adjustable cantilever strip.Magnification of the instrument depends upon the length, width, and a number of twists of the twisted strip.This will cause the pointer to rotate by an amount proportional to the change in the length of the strip.Any vertical movements of the plunger make it to twist or untwist.Thus the vertical movement of the plunger transmitted to the metal strip through the elbow.Its inner end is attached to the other arm of spring elbow. The measuring plunger is mounted on a flexible diaphragm.One end of the strip is fixed to an adjustable cantilever strip and the other end is attached to an arm of spring elbow.The two halves of the strip from the Centre are twisted in opposite directions, so that any pull in the strip causes the Centre and hence the pointer to rotate.A very light glass pointer is attached to the Centre of the twisted strip.The instrument consists of a plunger, twisted thin metal strip, spring elbow, pointer, etc.It works on the principle of a button spinning on a loop of string.Johansson “Mikrokator‟ is a mechanical comparator having a magnification of about 5000.The magnification of plunger movement can be obtained mechanical means such as levers, gear and pinion arrangement, or other mechanical means. The general principle of the comparator is to indicate the difference in size between the standard and work being measured by means of some pointer on the scale with sufficient magnification. This cannot be used as an absolute measuring device but can only compare two dimensions.They will show only the deviation in size. Comparators normally will not show the actual dimensions of the workpiece.It is quick and more convenient for checking a larger number of identical dimensions.Comparators are one form of the linear measurement device.Difference between Measuring Instruments and Comparators :.Difference between Gauges and Comparators :.The disadvantage of electrical comparator.Difference between Mechanical Comparator and Pneumatic Comparators.Disadvantages of pneumatic comparators :.Working principle of Optical comparators:.Disadvantages of Mechanical Comparators.Working Principle of Mechanical comparators:.All you need to do is drag or upload the files and let Copyleaks do the rest of the work.
