3 Overview

Needle gauge, three-pin is of a nominal diameter of the measuring cylinder. Set the amount of needle gauge, mostly spaced by a certain size With the general inspection aperture for the workpiece; standard gauge needles used for instrument calibration. Three needles are usually used in groups, three diameters The same as a set of three needles, thread diameter for measurement. Needle gauge, three needle-like Figure 1. Figure 1 all kinds of needle gauge, three-pin schematic 1- three-pin; 2- fixed three-pin; 3-pin regulations; 4 - type needle regulations petiole

4 Metrological characteristics

According gauge needle, three needles purposes, it should be calibrated following metrological characteristics. --- Roundness; --- Plain line straightness; --- Diameter and the diameter variation. Note. Metrological characteristics related product standards set forth in Appendix A.
