Characteristics and Applications of Vibration Galvanometers [PDF]
Transactions of the American Institute of Electrical Engineers, 1912 In the vibration galvanometer we have a type of synchronous motor which is distinctly different from all the ordinary types of dynamo electric machines. Further it does not have any of the characteristics of any of the ordinary galvanometers and except for the fact that it is used in the detection or measurement of small currents and voltages, it ...
