A potentiometer is a three- terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. [1] 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 ...
A throttle position sensor (TPS) is a sensor used to monitor the throttle body valve position for the ECU of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle. More advanced forms of the sensor are also used. For example, an extra "closed throttle position ...
Electronic throttle control (ETC) is an automobile technology that uses electronics to replace the traditional mechanical linkages between the driver's input such as a foot pedal to the vehicle's throttle mechanism which regulates speed or acceleration. This concept is often called drive by wire, [1][2] and sometimes called accelerate-by-wire ...
This may not be the case when a digital potentiometer is used. Both electro-mechanical and digital potentiometers generally have poor tolerances (typically ±20%), [7] poor temperature coefficients [8] (up to many hundreds of ppm per degree C), [8] and a stop resistance that is typically about 0.5-1% of the full scale resistance. Note that stop ...
A dashpot, also known as a damper[citation needed], is a mechanical device that resists motion via viscous friction. [1] The resulting force is proportional to the velocity, but acts in the opposite direction, [2] slowing the motion and absorbing energy. It is commonly used in conjunction with a spring. The process and instrumentation diagram ...
Rotary encoder. A Gray code absolute rotary encoder with 13 tracks. At the top, the housing, interrupter disk, and light source can be seen; at the bottom the sensing element and support components. A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to ...
Vibrator (electronic) A pair of Heathkit -brand vibrators manufactured by James Electronics, with octal bases. The one on the right has been stripped of the aluminum cap so the inner components can be seen. An electro-mechanical vibrator from the Grass Instrument Co. Used as part of a chopper amplifier in polygraph input amplifier.
Motorized potentiometers are used in industrial controls. [ 1] Motorized potentiometers may be used for remote control applications. [ 3] Motorized potentiometers can be used to build electrical/electronic analog computers. The motorized potentiometer can act as a computing element, but also as a way to convert a physical into an electrical value.
