STAND KSD-2 FOR METROLOGICAL SUPPORT OF LASER AND OPTICAL SPEED AND LENGTH METERS
Annotation
The current state of the art in the field of metrological support for laser and optical speed and length meters is discussed. The relevance of improving the reference base for metrological support of such tools in accordance with modern needs is shown. To solve the problem, the KSD-2 stand for measuring speed and length (distance traveled) is developed, allowing measurements of speed in the range of 0.1–50 m/s and length in the range of 1–99999 m. A description of the design and operation principle of the stand is presented, and experimentally determined metrological characteristics of the stand are given. The main contributions that make up the confidence limits of the relative error in measuring the speed and length (traveled path) of the KSD-2 stand are considered. The results of the study are of interest to metrologists working in the field of measuring mechanical quantities, design engineers, as well as manufacturers and users of laser and optical speed and length meters.
