This kind of potentiometer appropriate makes functional potentiometer, in consumptive kind electronic product apply in great quantities. The production of carbon film can be automated by printing process. Organic solid core potentiometer: the range of resistance is wider, resolution is high, heat resistance is good, overload ability is strong, wear resistance is better, reliability is higher, but heat resistance and dynamic noise are poor. This kind of potentiometer is generally made of small semi-fixed form, in the circuit for fine tuning. Metal glass glaze potentiometer, it has both the advantages of organic solid core potentiometer, and has a small resistance temperature coefficient (and wire-wound potentiometer close), but the dynamic contact resistance is large, the equivalent noise resistance is large, so it is used for semi-fixed resistance adjustment. This kind of potentiometer develops very fast, bear temperature, bear wet, bear the ability of load impact already got improvement, can work reliably below harsher environmental condition. Conductive plastic potentiometer: wide range of resistance, high linear accuracy, resolution, and long wear life. Although it has a large temperature coefficient and contact resistance, it can still be used to control analog and servo systems in automatic meters.

Three, the role of potentiometer Potentiometer has a lot of types, the action function of different potentiometer can be all different, but general potentiometer can have 3 basic effects 1, the first role: current control Some of the current control belongs to the precision potentiometer, only in this way the current value will get more accurate value, the current output end is selected sliding contact lead end, the potentiometer can be used to control the current size; 2, the second role: distribution voltage Using the nearly linear relationship between resistance and voltage, adjusting the resistance value can adjust the voltage distribution relationship, achieve stepless adjustment of output voltage, such as in the humidifier and other aspects; 3, the third role: change resistance When the circuit needs to input the parameters of resistance resistance value can be used potentiometer, when the potentiometer connected into both ends of the device, the potentiometer in the range of travel can obtain a smooth continuous change of resistance value, then the potentiometer is to change the role of resistance.
