| Abstract: |
| A new type of thin film temperature sensor is discussed in the paper. The sensor is coated with a vacuum coating method on the surface of a turbine blade.B-ecause both the sensor and blade are combine together, the sensor can measure accurately the surface temperature. It has the advantage of light weight, rapid response and no interference in heat transfer within blade and gas flow over blade,The sensitive element of the sensor is PtRh10/Pt thermocouple. The maximum temperature is up to 1000℃and the accuracy is within±3 %. |
