3 Overview

Comparator is the use of a torsion spring element as size conversion and amplification or optical transmission amplification principle, the measuring rod straight Linear displacement into a pointer or index measuring instruments arcuate line in the upper corner of the displacement of the indexing plate. Its main purpose is to comparison Measurement precision parts geometry, it can also be used as gauge of certain measuring devices and other common exterior structure shown in Figure 1 ~ image 3.
