What is a Dimension measuring instrument?

A dimensional measuring instrument is an instrument or machine that measures the dimensions of an object, and can be said to be one of the displacement meters because it can measure the amount of movement of an object. It includes calipers and micrometer that measure by hand, but recently, machines that can measure dimensions automatically and are non-contact and do not require tools are on sale. Mechanical dimensional measurement can reduce the error of measurement by humans, and there are some models that can measure points that cannot be measured with a caliper or a micrometer. The principle differs greatly depending on the machine, and it is necessary to select it according to the application.

Application of Dimension measuring instrument

Dimension measuring instruments are usually used for products that take a long time to measure or are difficult to measure. Since it can be measured in a short time, it is also used for 100% inspection of products. For example, it is possible to perform precise measurements such as the length, width, and phase measurement of the groove machined in the shaft, such as measuring the journal diameter of the crankshaft, the outer diameter of the glass tube, the meandering of the sheet, and the outer diameter of the wafer. It is The projection type dimensional measuring machine can also measure fluctuations such as elongation and thinning during tensile tests.
