Minneapolis-Honeywell Rubicon Instruments Potentiometer Bridge Model 2780 17"

Description

Circa mid to late 20th century Minneapolis-Honeywell Regulator Company - Rubicon Instruments - Philadelphia, PA - Made in USA - Model No. 2780 - Potentiometer. Wood case with black Bakelite top - III609.

"The Rubicon Company was established in Philadelphia in the 1930s. They specialized in electrical measuring instruments used for laboratory and testing services. The company was purchased by the Minneapolis-based Honeywell Regulator Company in 1957, where it became the Rubicon Division of Honeywell." (Source: MIT Museum)

"A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. It is also used in speed control of fans. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load."
