Characteristics and parameters of organic solid potentiometer

　　Solution: Check whether the machine works normally in addition to the automatic conveyor, if there is no fault in other parts, it is likely to be a problem with the potentiometer. Potentiometer, on the front of the baler, there are four buttons on the operation panel, from left to right are the power switch, the potentiometer, the reset button, and the tape feed button. The potentiometer of the baler is a rotating button marked with a scale around it, which is used to control the length of the automatic tape feed after the packaging is completed. If there is more than a conveyor belt, and the automatic conveyor belt is no problem, most of it is caused by potentiometer failure.

　　Debugging method: Turn the potentiometer to the minimum scale, and then fine tune, in the range of organic solid potentiometer, characteristics, parameters, the machine can be normally sent. If the conveyor is normal within a certain interval, it is certain that the potentiometer is faulty. The next step is to replace the potentiometer.

　　The mechanical life of the potentiometer is also called the wear life, and the mechanical durability is commonly expressed. Mechanical durability refers to the total number of reliable movements of the organic solid potentiometer with moving contact under specified test conditions, characteristics, and parameters, commonly expressed as "weeks". The mechanical life is related to the type, structure, material and manufacturing process of the potentiometer, and the difference is quite large.

　　In addition to the above characteristic parameters, organic solid potentiometers, characteristics, parameters Potentiometers also have rated power, resistance allowable deviation, maximum operating voltage, rated operating voltage, insulation voltage, temperature parameters, noise electromotive force and high frequency characteristics and other parameters

　　Sliding noise is a characteristic noise of potentiometer. When changing the resistance value, due to the improper distribution of the potentiometer resistance, the improper coordination of the rotating system and the contact resistance of the potentiometer, the moving contact will move on the surface of the resistor, and the output end will have useful signals, but also the organic solid potentiometer, characteristics, parameters accompanied by noise that fluctuates with the signal.

　　For a wire-wound potentiometer, in addition to the above-mentioned contact noise of the moving contact organic solid potentiometer, characteristics, parameters and the winding organic solid potentiometer, characteristics, parameters, there are also resolution noise and short-circuit noise. Resolution noise is caused by the stepwise nature of resistance changes
