Abstract :
A discussion of a magnetic-drag-tachometer equipment designed principally for aircraft use. The principle of operation makes possible an indicator which may be read very accurately under extreme conditions of aircraft use and at the same time may be easily adjusted and maintained. Because of the extreme reading accuracy obtainable, low inherent temperature errors and good compensation are essential. A method of obtaining these features is presented.
