How to detect the duplex potentiometer_ How to judge the quality of the double potentiometer? This requires us to test its performance. Today, we will explain in detail the steps to test the dual potentiometer. 1. Measure the resistance values of the two groups of potentiometers on the dual-connected potentiometers (i.e., the resistance values between A and C and the resistance values between A 'and C') with the appropriate range of the resistance range of the multimeter, and check whether they are the same and consistent with the nominal resistance values. 2. Short-circuit potentiometers A, C 'and potentiometers A' and C with wires respectively, and then use a multimeter to measure the resistance value between the center head B and B '. Under ideal conditions, no matter where the rotary shaft of the potentiometer is turned, the resistance value between B and B' should be equal to the resistance value between A, C or A 'and C' (that is, the pointer of the multimeter should always be kept at A

What if the rotating noise of the adjustable potentiometer is loud_ The problem we will encounter is that the rotating noise of the adjustable potentiometer is large, so how to solve it? Today, I will teach you how to clean and repair the problem of loud rotating noise of the adjustable potentiometer. The specific method is to fold the pure alcohol detergent to the carbon film inside the adjustable potentiometer, and turn the handle continuously to make the contact slide on the carbon film to achieve the purpose of cleaning the carbon film and contact. This cleaning can be carried out with power on. It should be noted here that pure alcohol must be used. Then turn the crank to listen to the noise until it disappears. How to make the cleaning fluid flow onto the carbon film? 1. For direct-slip carbon film potentiometers: drip from the handle gap. 2. For carbon film potentiometers that cannot flow from the outside:

Brief introduction of several encoder installation and connection methods_ As for the installation and connection mode of encoder, we have found a brief introduction of coupling, direct connection and flange installation on the Internet for your reference. You can determine the installation and connection mode of encoder according to your actual needs. Encoder is a small part in a complex system. It can help manufacturers produce high-quality parts or move objects from point A to point B quickly and smoothly. If you decompose the system, its main components include 1 motor, 1 driver or amplifier, possibly 1 brake and 1 encoder. The encoder is the most troublesome during installation. This article will introduce different encoder installation methods and their advantages and disadvantages from the perspective of space, surrounding environment and mechanical factors, and will also introduce

Potentiometers can be divided into exponential potentiometers, logarithmic potentiometers and linear potentiometers according to the linear change rule of resistance value. The so-called resistance linearity of the potentiometer refers to the relationship between the rotation angle (or stroke) of the potentiometer and the output voltage when used as a voltage divider. The relationship between the resistance value of the potentiometer and the rotation angle of the contact point of the slider can be any functional form in theory. The resistance change characteristic of the potentiometer refers to the relationship between the resistance of the potentiometer and the length of the moving contact or the rotation angle of the rotating shaft, that is, the resistance output function characteristic. There are three common types: 1) Resistance change characteristics of exponential potentiometer

How to judge whether the dial potentiometer is broken_ The dial potentiometer is a potentiometer commonly used for tuning function. There are three pin dial potentiometers and five pin dial potentiometers. They are used more frequently in the audio system. So sometimes the audio system is bad. Is the dial potentiometer bad? The following methods are for you to judge! 1、 It is recommended that you open the four feet on the black base of the potentiometer and wipe the resistance coil with alcohol to see the effect; 2、 You are now on the 200th gear, and 09.7 is abnormal in terms of data; 3、 You connect the meter rod to the foot on the two sides and measure whether the total resistance value is within ± 5% of 100 Ω, and 95 Ω - 105 Ω is normal; 4、 As for the minimum display of 0.5 Ω, it is normal from our manufacturer's data. Because there is zero position
