一、温度均匀性测试影响因素在温度均匀性检测过程中,涉及两套测量控制系统:一是炉温控制系统,二是温度均匀性测试系统。温度均匀性测试结果的影响因素也主要来自这两个方面。1.控温系统温控系统一般由热电偶、补偿导线、温控仪表或PLC等部分组成,各组成部分的误差、检测热电偶的位置、参考端温度、仪表控制调节参数的选择都会对控温质量产生影响,从而导致测试准确度的失准。 First, the temperature uniformity test influencing factors In the process of temperature uniformity testing, involving two sets of measurement and control system: First, furnace temperature control system, the second is the temperature uniformity test system. Temperature uniformity test results also affect the main factors from these two aspects. 1. Temperature control system Temperature control system generally consists of thermocouple, compensation wire, temperature control instrumentation or PLC and other components, the error of each component, the location of the test thermocouple, the reference temperature, the control parameters of the instrument control selection will control Temperature quality impact, resulting in the accuracy of the test accuracy.
