热电偶的结构要求是什么

热电偶的结构形式为了保证热电偶可靠、稳定地工作，对它的结构要求如下：

1、组成热电偶的两个热电极的焊接必须牢固；

2、两个热电极彼此之间应很好地绝缘，以防短路；

3、补偿导线与热电偶自由端的连接要方便可靠；

4、保护套管应能保证热电极与有害介质充分隔离。

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.
