Industrial application of Rototrol regulators

The Rototrol has been applied in considerable numbers to a wide variety of industrial applications. It has met adequately the need for a simple and reliable regulator which is capable of withstanding the rigors of general industrial usage and which is sufficiently elemental in operation that it can be understood by nontechnical maintenance personnel. It has been accepted enthusiastically by industry, and applications in both existing and new fields are increasing rapidly. This paper discusses the fundamental theory of the Rototrol, the application of the circuits most commonly used, and cites operating results for typical installations.
