Typically, comparators are utilized for linear measurements, and currently, there exists a plethora of types, each distinguished by their approaches to amplification and recording of measured discrepancies. Modern engineers strive to categorize comparators into high and low amplification groups, reflecting the complexities of the underlying technology. These categorizations are based on the amplification and recording principles employed, encompassing mechanical, mechanical-optical, electronic, electrical, pneumatic, as well as other variants like multi-check and projection comparators. These diverse comparator options afford users the flexibility to choose an appropriate and cost-effective solution tailored to specific metrological needs. This article offers an insight into a mechanical comparator, elucidating its functionality and practical applications.
