Rotary Potentiometers, Rheostats

Rotary Potentiometers and Rheostats are two types of variable resistors which uses a turning wheel to control resistance. The PTV111-1415A-A105 is a potentiometer, a type of variable resistor whose variable resistance is based on the position of the wheel. Its application field and working principle will be discussed in this article.

Application

The PTV111-1415A-A105 is mainly used in a variety of applications such as sound volume control, robustness testing, and audio frequency testing. It is especially suitable for guitars and other musical instruments where the user needs to adjust the tone. It can also be used for temperature control in heating elements where the temperature can be adjusted depending on the position of the wheel. The device is also suitable for motor speed adjustment as well as motor speed/torque regulation.

Working Principle

The PTV111-1415A-A105 is a type of potentiometer which works principle relies on a linear voltage divider. Essentially, the resistance is determined by the position of the wheel along the resistance track of the potentiometer. Each resistance track is composed of many turns of wire which changes in value based on the movement of the wheel. The fixed contact is attached to the resistance track and the wiper arm is attached to the wheel which can move along the track. As the wheel moves, the voltage at the wiper terminal changes and can be measured and used to control the resistance.

The PTV111-1415A-A105 is a single turn potentiometer which means it uses only a single track to control the resistance. The device has an adjustable dial which allows the user to control the resistance to a specific value. This is done by setting the wheel to the desired resistance and then adjusting the dial to the desired value.

The device offers a wide range of resistance values while still being small and lightweight. It has a rated resistance of up to 1Mn and can withstand temperatures ranging from -40°C to +70°C. The PTV111-1415A-A105 is also highly accurate and has a long life expectancy of up to 5 years.

Conclusion

The PTV111-1415A-A105 is a single turn potentiometer which uses a linear voltage divider to control resistance. It is mainly used in applications like audio equipment, robustness testing, temperature control, and motor speed/torque regulation. The device is highly accurate and can withstand temperatures ranging from -40°C to +70°C. Furthermore, it has a long life expectancy of up to 5 years.
