Mechanical Comparators

Mechanical comparators:

Mechanical comparator employs mechanical means for magnifying small deviations. The method of magnifying small movement of the indicator in all mechanical comparators are effected by means of levers, gear trains or a combination of these elements. Mechanical comparators are available having magnifications from 300 to5000 to 1. These are mostly used for inspection of small parts machined to close limits.

Types of Mechanical Comparators:
          1. Dial indicator
          2. Reed type mechanical comparator
          3. The Sigma comparator
