Drum-shaped measuring standard |
摘要 |
A measuring standard to measure the rotational speed of a machine is described. A ring (4) is integrally secured to the periphery (1.1) of a drum-shaped base member (1), by using soldering in accordance with the present invention. Through soldering, a stable measuring standard for an angular-position measuring system is created for high rotational speed applications.
