mõõtmisnäitaja

Mõõtmisnäitaja, commonly translated as measuring indicator or dial indicator, is a precision instrument used to measure small distances or variations in a workpiece. It is characterized by a graduated dial and a movable pointer that indicates these measurements. The primary function of a mõõtmisnäitaja is to provide highly accurate readings of deviations, flatness, parallelism, and concentricity.

The instrument typically consists of a metal housing containing a mechanism that amplifies small movements of a stylus or probe. This stylus is brought into contact with the surface being measured. As the surface moves or changes shape, the stylus reciprocates, and this motion is translated into the rotation of the pointer on the dial. The dial is usually marked with a scale, often in millimeters or inches, allowing for precise readings down to fractions of a millimeter or thousandths of an inch.

Mõõtmisnäitajad are widely used in various industrial and manufacturing settings, including machining, quality control, inspection, and assembly. They are essential tools for ensuring that manufactured parts meet precise specifications and tolerances. Different types of mõõtmisnäitaja exist, including mechanical, electronic, and digital versions, each offering varying levels of precision, features, and ease of use. Their robustness and reliability make them indispensable for accurate dimensional metrology.
