Rotary Rheostat And Potentiometer Application

Views: 0 Author: Site Editor Publish Time: 2022-07-13 Origin: Site

L&G lgSwitch series RHEOSTAT adjustable resistor used in applications that require the adjustment of current or the varying of resistance in an electric circuit. The rheostat can adjust generator characteristics, dim lights, and start or control the speed of motors. Its resistance element can be a metal wire or ribbon, carbon, or a conducting liquid, depending on the application. For average currents, the metallic type is most common; for very small currents, the carbon type is used; and for large currents, the electrolytic type, in which electrodes are placed in a conducting fluid, is most suitable. A special type of rheostat is the Potentiometer, an instrument that measures an unknown voltage or potential difference by balancing it, wholly or in part, by a known potential difference. A more-common Potentiometer is simply a resistor with two fixed terminals and a third terminal connected to a variable contact arm; it is used for such purposes as a volume control in audio equipment.

L&G LGSWITCH RHEOSTAT

Product Name : RT Rheostat

Control the electrical resistance of a circuit without interrupting the flow of current.

The rheostat is consisted of ceramic core and a resistive wire wrapped to form a toroid coil with a wiper axle.

Can be used widely as light dimmers and motor speed control, is applicable for arc lamps, pumps, fans and blowers, respirators, dental and model trains or other applications that require high voltage and current.
