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 ...
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 ...
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 ...
A Hall probe is a device that uses a calibrated Hall effect sensor to directly measure the strength of a magnetic field. Since magnetic fields have a direction as well as a magnitude, the results from a Hall probe are dependent on the orientation, as well as the position, of the probe.
Trimmer (electronics) A trimmer, or preset, is a miniature adjustable electrical component. It is meant to be set correctly when installed in some device, and never seen or adjusted by the device's user. Trimmers can be variable resistors (potentiometers), variable capacitors, or trimmable inductors. They are common in precision circuitry like ...

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 ...
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 ...
