311902 Rotating Platform
Rotating PlatformFor experiments in which certain components are to be continuously turned and the respective angles determined either with a recorder or via a computer interface (CASSY), e.g. diffraction experiments with ultrasonic, angular distribution of micro-waves. The system is driven by a DC gear motor and friction roller; rotary motion is registered via an additional friction roller and a five-turn potentiometer. The rotational angle is proportional to the change in resistance. An angle scale (5° scale division) is printed on the rotating platform; a 4-mm hole is through the center.
