Causes of pressure switch measurement error
In general, the reasons for the error are as follows:
1. Although there are a large number of pressure switches on the market at present, due to the different conditions of the manufacturers, the products themselves are different in material. The products produced by various enterprises are often different in terms of service life and product specifications, which determine the length of service life of the products. Even some enterprises use low-grade materials in order to reduce production costs, which gradually emerged in the later use process. Such a problem.
2. Since precision instruments and meters are generally put into production after being verified by the laboratory, and the products are applied to the production enterprises, the frequency of use of the pressure switches is far beyond the laboratory. In this way, the accuracy of the measured data in the laboratory, as the frequency of use of the product increases and the number of years of use increases, the accuracy of the measured data deviates from the measurement data of the laboratory.
3, artificial factors, commonly used pressure switch pressure gauges are very fine, the operator after a long period of labor, due to fatigue, there are often misunderstandings, even misjudgment. So this may also be a cause of measurement bias.
4. During the working process of the pressure switch, the operator may also cause measurement deviation due to different judgments and readings.
