Manufacturing method of non-adjustment pointer type pressure gauge and product

The invention discloses a manufacturing method of a non-adjustment pointer type pressure gauge. The manufacturing method comprises the following steps: a new-made pointer type pressure gauge and a standard pressure gauge are mounted on the same pressure source; the pressure source outputs pressure, and an industrial camera acquires position images of numerical point pointer on a disk one by one; image processing equipment draws the disk, and output printing equipment prints the disk; the disk is mounted at the position where the new-made pointer type pressure gauge is located. The invention further relates to the non-adjustment pointer type pressure gauge manufactured by the method disclosed by the invention. According to the manufacturing method of the non-adjustment pointer type pressure gauge, the problems of long adjustment time, low accuracy, low stability and the like of the conventional manual adjustment are solved; the manufacturing method has the characteristics of simple operating step, high practic
