Mikromõõtja

Mikromõõtja is an Estonian term that translates to "micrometer" in English. A micrometer is a precision measuring instrument used to measure small distances with great accuracy. It operates on the principle of a screw thread, where a precisely machined screw rotates within a threaded sleeve. The advancement of the screw for each full rotation is a known, small increment, allowing for very fine measurements.

Typically, a micrometer consists of a frame, an anvil, a spindle, a sleeve, and a thimble. The object to be measured is placed between the anvil and the spindle. The thimble is rotated, advancing the spindle until it contacts the object. The measurement is then read from scales on the sleeve and the thimble. Different types of micrometers exist for various applications, including external micrometers for measuring outer dimensions, internal micrometers for measuring inner dimensions, and depth micrometers for measuring depths.

Micrometers are crucial tools in fields requiring high precision, such as manufacturing, engineering, and scientific research. They enable the accurate measurement of small components, tolerances, and material thicknesses, ensuring the quality and functionality of manufactured goods and experimental setups. The accuracy of a micrometer is typically in the range of micrometers or even fractions of a micrometer, making it indispensable for applications where even minor deviations are unacceptable.
