WebbPotentiometric titration is one of the important titration methods and is mainly carried out to characterize acid solutions. It follows a method similar to that of the normal titration technique, but the main difference is that there is no indicator used in the potentiometric titrations. Instead of using an indicator, electrodes are employed ... WebbPotentiometer circuit. In actual use, we generally ground pin 3 as the data input terminal. And pins 1 and 2 are connected to the I/O port of the microcontroller as the data output terminal. As shown in the figure, connect pin 1 to P1.0 of the microcontroller, and pin 2 to P1.1 of the microcontroller.

WebbA potentiometer is a three-terminal measuring device used to measure the unknown EMF of a source (such as a cell) by comparing it with a known EMF. The voltmeter is a two-terminal measuring device that is used to determine the potential difference (or voltage) between any two terminals in an electric circuit. WebbTPS is usually located on the throttle valve spindle so that it can directly monitor its position. The TPS sensor is a potentiometer, providing a variable resistance depending on the position of the throttle valve (and hence throttle position sensor). The sensor signal is used by the engine control unit (ECU) as an input to its control system.
