氮化硅热电偶保护管
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。
保护管与热电偶配套使用，可保护热电偶在特殊环境下正常工作。
氮化硅是目前世界上最有效的广泛应用于有色金属铸造测温及 其控温用的材料。
Thermocouples are the most-used temperature sensors. The long-term stability and service life of thermocouples are closely related to protection tubes.Silicon nitride thermocouple protection tubes can protect the thermocouples to measure temperature accurately and rapidly in non-ferrous metals.
