熱電偶的結構要求是什么

熱電偶的結構形式為了保證熱電偶可靠、穩定地工作，對它的結構要求如下：

1、組成熱電偶的兩個熱電極的焊接必須牢固；

2、兩個熱電極彼此之間應很好地絕緣，以防短路；

3、補償導線與熱電偶自由端的連接要方便可靠；

4、保護套管應能保證熱電極與有害介質充分隔離。

In order to ensure the reliable and stable operation of the thermocouple, the structural requirements of the thermocouple are as follows:

1. The welding of the two thermoelectrodes forming the thermocouple must be firm;

2. The two hot electrodes should be well insulated from each other to prevent short circuit;

3. The connection between the compensation wire and the free end of the thermocouple should be convenient and reliable;

4. The protective sleeve should be able to ensure that the hot electrode is fully isolated from harmful media.
