摘要
本文指出厚膜铂热电阻在-79～600℃范围内是能符合IEC751-83对绕丝式铂热电阻的分度允差的,但厚膜铂热电阻的分度曲线与绕丝式有着较大差别。本文较详细地介绍了其分度特征及减少其与IEC751-83偏差的方法。
The article states that within the range ot -79°to 600℃, the scaling tolerance of thick-film Pt RTD conforms to the IEC 751-83 Standard suitable for thread-wound Pt RTD, but the scaling curves of these two types of RTDs are quite different. The scaling features of thick-film Pt RTD and the method of reducing the deviation from IEC 75l-83 Stan-dard are described in detail.
