摘要
温度测量是科研、工业生产中最常见的参数测量,尽管测温仪表结构简单,若使用不当,仍然会产生较大测量误差。通过对接触测温法测温精度的分析,了解掌握误差产生的原因,对引起测温误差的因素和测温元件的特性的了解,通过采取必要的措施,有些误差是可以避免和减小的,这对提高测量精度,延长测温仪表使用寿命有一定帮助。
temperature measurement is the most common parameter measurement of scientific research, industrial production, although the temperature measuring instntment is simple in structure, if used improperly, it will still have a large measurement error. Through the analysis of the accuracy of contact temperature measurement, to understand the reason of error produced by master, on the temperature characteristics of error factors and the measurement components through understanding, take the necessary measures, some errors can be avoided and reduced, which is to improve the measurement precision, has certain help prolong the service life of temperature measuring instrument.
