摘要
为了了解不同环境对热电偶测温精确性的影响,通过对0.5 mm康铜丝与铜丝制成的热电偶和18芯9对电缆所制成的热电偶,在工作端的导线受热或受冻长度不同的条件下进行试验,得出热电偶标定环境与实测环境不同,被测量的温度有一定的差异。所以在标定时应了解被测点的环境,并与实际环境相似,这样测得的温度将更加准确。
The accuracy of temperature measuring data has importance for studying the temperature change of frozen wall.Through the test to the different thermocouples with different heated or frozen length of measured line,the result was obtained,showing that when calibrated environment is similar to actual measurement,the temperature measured is more accurate.
