For wire wound potentiometer performance promotion, EVERSON's scientific and technical personnel had got some breakthroughs in global technical analysis and material innovation based on 8 years experiments. Normally, the key characteristcs which influence wire wound potientometer show up in four ways, such as wire material, element base material, contactor and lube oil.
First, EVERSON guys used the special wire material, the wire we used can get 10Kohms~25Kohms pot in Φ24mm potentiometer. Although the material diameter is just 0.015mm, the wire stength is over other 0.05mm diameter material.
Second, EVERSON guys through the processing of various types of contactor surface analysis and materials research found a high abrasive materials and excellent surface treatment.The material have been passed laboratory verification.
Third, for element bae , EVErSON guys through a series of materials study, find and excellent synthetic plastic insulation, this material mainly composed of PTEE, couple with some auxiliary additives, which make the material dget strong strength, and not easy to deformation. So that the resistance wire is evenly arranged on the surface of the base to ensure the product precision. At the same time, the resolution of the product can be adjusted through the design of the element base. The material is not only have the lower cost, but also the flexibility is very good. we call it as a magic weapon for improving the service life of the wire wound potentiometer.
Fourth, the wire machine that we choose is an upgraded version of a well-known international brand of wire macine. The machine have higher precision, and the upgraded version of the wire equipment can also do to improve the precision.
Fifth, EVERSON guys through comparison of the characteristics of various types of oil, and the deployment an test of nearly 5 years of oil. Finally, we got the oil which can increase more than 10 times product service life.
