3 Overview

Block comparator compares the measured quantity is the block length measuring instruments. Block vertical placement mode. Block comparator generally consists of machine body, one or two displacement sensors, monitors, controllers and other components. through Through the displacement sensor in contact with the upper and lower gauge block measuring surface (or just in contact with the measuring surface, measured at the surface in contact with the fixed point) Displacement occurs, you can block and the length of a standard amount of the difference between the measured block was measured. According displacement sensor Different, divided into inductive, grating, laser type and other types.
