Rotary Potentiometers, Rheostats

A rotary potentiometer, also known as a variable resistor or digital potentiometer, is an electronic component used for measuring electric potential (voltage) or other electrical quantities. In a rotary potentiometer, a potentiometer is typically used in either a variable resistor network, or in combination with other components such as switches to create a voltage divider. In addition, rotary potentiometers can be used as voltage regulators, in conjunction with an adjustable power source.The 81A1A-B28-A15 is a rotary potentiometer that is used in a variety of applications in order to adjust the voltage of a circuit. It is a three terminal device that has an adjustable contact arm and a resistance element.The working principle of the 81A1A-B28-A15 is quite simple. As the contact arm is adjusted, it modifies the resistance between the first and second terminal. This in turn modifies the voltage drop across the resistance element. Thus, the output voltage can be adjusted simply by altering the position of the contact arm.When it comes to the various applications of the 81A1A-B28-A15, it is used in a wide range of electrical and electronic devices. Common applications include volume control in audio equipment, controlling fan motors, and adjusting brightness of displays. It can also be found in light dimmer switches, motor speed controllers, and gas flow controllers.In addition to all of the above, the 81A1A-B28-A15 is also popularly used in regulating PID controllers, which are commonly found in the industrial automation industry. PID stands for Proportional-Integral-Derivative and refers to a type of control system that adjusts its output based on the difference between a desired value and an actual value. This type of control system is extensively used in controlling temperature, pressure, flow, and other process variables.On the whole, the 81A1A-B28-A15 is an important component in the field of electrical engineering that can be used to measure electric potential and other electrical quantities, in a wide range of applications. The rotary potentiometer offers convenience, as it can be used to adjust voltage quickly and easily by just adjusting the contact arm. Moreover, its use is not limited to just one application, and can be found in industrial automation, light dimmer switches, audio systems, motor speed controllers and many more.
