Background
The dial indicator was manufactured by b.c. Ames in 1890. Are commonly used for shape and position errors and for length measurement of small displacements. The dial plate of the dial indicator is printed with 100 equal-division scales, namely, each division value corresponds to 0.01 millimeter of movement of the measuring rod. If 1000 equal division scales are printed on the dial plate, each division value is 0.001 mm, and the measuring tool is called a dial indicator. The shape of the measuring head is changed and the corresponding bracket is matched, so that the deformed variety of the dial indicator, such as a thickness dial indicator, a depth dial indicator, an inner diameter dial indicator and the like, can be manufactured.
