摘　　要：以双屏吹气式热电偶为基本结构,采用计算与试验相结合的方式,设计了一种适用于航空发动机试车台现场的K型参考温度传感器,用以对现场测温的传感器进行校准,以期解决涡轮后气流温度传感器的校准问题,并为此类参考温度传感器的设计提供一定的参考。Taking the two-shielded blowing thermocouple as the basic structure, combining the calculation with the experiment and in order to solve how to calibrate the gas flow temperature sensor behind the turbine, a kind of K type reference temperature sensor adapted for the in-situ aero-engine test bed is designed and used to calibrate the in-situ measuring temperature sensor. Thus a reference for the design of this kind of rieference temperature sensor is provided.
