Abstract

The speed-of-rotation transducer of reflection type designed for measuring rotational speed up to 145 000 rpm at the distance of 20 mm from the tested shaft under cryogenic temperatures is presented. The general transducer operating methods, its design, obtained performance specifications and their theoretical and practical underpinning are stated.

Key words

speed-of-rotation transducer of reflection type; fiber-optic bundle; optical receiver; radiation emitter; glass seal; rise and fall time for optical receiver; LED direction pattern.
