Disadvantage of bourns 100 turn potentiometer

Because temperature change, abrasion and fouling between slider and variable resistor will cause resistance change and affect the accuracy of potentiometer, so the accuracy of potentiometer is too low. Due to the development of materials, especially conductive plastics, potentiometers can maintain their original characteristics after a long time of use, and improve their performance at the same time.

The disadvantages of bourns 100 turn potentiometer are: 

1. The accuracy is not good and can not be used as precise servo control (such as the main position feedback device of the manipulator). 

2. When the brush moves, it keeps in contact with the resistance and causes wear. 

3. Potentiometer output will be affected by environment. 

4. Analog to digital conversion devices are needed to provide digital output to the controller (computer). 

5. Under the vibration environment, the resistance will change (limit value: 2%~7.5%).
