Pointer Inductance Micrometer DGB-5B
The instrument can be used in combination with DGC-8ZG/C or DGC-6PG/A type inductive sensors (I. e. inductive measuring heads) for precision measurements in machining. With the corresponding measuring device can measure the workpiece thickness, inner diameter, outer diameter, straightness, flatness, parallelism, perpendicularity and runout. Two inductive sensors can also be used for sum-difference calculus measurement, which has the advantage of eliminating the positioning error of the workpiece during measurement, thereby improving the measurement accuracy.
