N型热电偶 Thermocouple type-N

 N 型热电偶由镍铬硅合金（NiCrSi+）和镍硅合金（NiSiMg-）构成，是一种为替代K 型热电偶而设计的改进型热电偶。其突出的优势在于高温稳定性和抗氧化性能优于K 型，因此在一些关键工业场合（如高温连续测量、要求长期稳定性的环境）中得到广泛应用。

     The Thermocouple Type N is composed of NiCrSi+ and NiSiMg-. It was developed as an improved alternative to Thermocouples Type K , offering superior high-temperature stability and oxidation resistance. It is widely used in critical industrial applications requiring long-term accuracy and durability under elevated temperatures.
