作为温度测量和调节的常用检测元件,铠装热电偶具有熊弯曲、耐高压、反应时间快和坚固耐用等许多特殊优点。但是,用户往往不知道选用绝缘式还是接壳式铠装热电偶为好。 从结构上看,绝缘式的测温点与热电偶头部绝缘,在通常条件下,热电极与铠套之间的绝缘电阻每米不少于5MΩ(100V),而接壳式的测温点与热电偶头部焊在一起。
As a common temperature measurement and regulation of detection components, armored thermocouple bear bending, high pressure, fast reaction time and many other special advantages of durability. However, users often do not know the choice of insulated or sheathed thermocouple shell as well. From the structural point of view, the insulated temperature measuring point is insulated from the thermocouple head. Under normal conditions, the insulation resistance between the hot electrode and the armor sheath is not less than 5MΩ (100V) per meter, and the junction temperature measurement Point with the thermocouple head welding together.
