The author has presented the report of dielectric type (condenser type or electrostatic type) high frequency generator. Besides this generator, the rotating machine and sliding apparatus of this type are utilized as controlling or measuring elements such as deviation detector, position detector, tachogenerator and so on.
This article is concerned with the voltage sensitivity of deviation detector of this type. Besides this type, there are many deviation detectors based on other principles. Pointed out as high sensitivity ones among them are differential transformer, Inductosyn, Vernier resolver, Telecote etc., all of electromagnetic induction type. Among these detectors, the Inductosyn type has most similar construction to that of the dielectric type. So, the voltage sensitivity of the dielectric type was compared with that of Inductosyn type. As the result of theoretical and experimental consideration, it was proved that the dielectric type has a superiority over others in voltage sensitivity.
