摘要
接触法测量所引起的误差主要包括沿测温元件导热引起的误差和测温元件热辐射所引起的误差等。为了减少误差 ,应注意材料和结构及安装地点的选择 ,并尽可能在测温元件外部加同温屏蔽罩。
The deviations caused by temperature measurement with contact method mainly cons ist of the deviation caused by thermal conduction of temperature measurement ele ment and the deviation caused by thermal radiation of temperature measurement el ement and so on.For decreasing the deviation,the material,its structure and the selection of installing place should be paid attention,and the isothermal screen ing can is put in the exterior of temperature measurement element as far as pos sible.
