3.3 Focus on temperature drift:
- Temperature drift is a comprehensive parameter. Although there is a test value, it is actually most relevant to Carbon (Conductive Plastic) Potentiometers.
- Factories cannot absolutely control it during the processing. This process involves multiple controls from materials to the processing stage, rather than simply relying on improving a single aspect to ensure the temperature drift value.
- Most industrial-grade requirements for temperature drift are less than 500 ppm, with many actually requiring below 300 ppm.
- Industrial products with high requirements for temperature drift may ultimately involve continuously testing and selecting products that meet the standards from a batch. Therefore, the yield rate, along with materials and processing methods, collectively determines the cost.
The processing method plays a crucial role in determining the final performance characteristics of the potentiometer. Each type undergoes specific manufacturing steps that enhance its suitability for different industrial needs.
3.4 Importance of Factory Test Reports
Factory test reports are essential in ensuring the quality and reliability of industrial potentiometers. These reports measure key parameters such as resistance tolerance, temperature stability, and mechanical wear. The yield rate, which indicates the proportion of potentiometers meeting quality standards, is also an important factor. Low yield rates can signal production issues, leading to higher failure rates in critical systems.
