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 ...
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 ...
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 ...
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 ...
The potentiometer is a simple device used to measure the electrical potentials (or compare the e.m.f of a cell). One form of potentiometer is a uniform high-resistance wire attached to an insulating support, marked with a linear measuring scale. In use, an adjustable regulated voltage source E, of greater magnitude than the potential to be ...
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.
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.
