Välismikromeeteriga

Välismikromeeteriga is a measuring instrument used to determine the external dimensions of an object with high precision. It is a type of micrometer, characterized by its C-shaped frame and a spindle that moves linearly when the thimble is rotated. The instrument typically consists of a calibrated screw, a measuring anvil, and a spindle. The object to be measured is placed between the anvil and the spindle. By rotating the thimble, the spindle is advanced or retracted until it makes firm contact with the object. The precise measurement is then read from the scales on the sleeve and thimble.

The accuracy of a välismikromeeteriga is significantly higher than that of a standard ruler or caliper, often reaching down to hundredths or even thousandths of a millimeter. This precision makes it indispensable in various fields, including machining, engineering, manufacturing, and scientific research, where tight tolerances are crucial. Different types of välismikromeeteriga exist, designed for measuring specific ranges of dimensions or for particular applications, such as digital micrometers that provide an electronic readout. Regular calibration and proper maintenance are essential to ensure the continued accuracy of the välismikromeeteriga.
