摘　　要：热电偶是应用最广泛的测温传感器。而热电偶的长期稳定性、使用寿命等各项性能指标,都与保护管密切相关。热电偶损坏率的高低直接取决于保护管材料的性能。因此,本文将详细介绍各种热电偶保护管的材料、性能、选用,以供相关技术人员参考。Thermocouple is one of the most common temperature measure sensor. However, the long-term stability, duration and other character indexes are all closely having relations with protective tube. The damage rate of thermocouple is directly determined with the material from which protective tube is made. So, this article will introduce the material, characteristic and selection for all kinds of thermocouple in detail and can be done as a reference for relative technicians.
