Development of thin-film thermocouple for measuring transient high temperature on spacecraft surfaces
摘要
Abstract
A K-type film thermocouple is developed for measuring the temperature on the spacecraft surface. The thermocouple film is fabricated on a high temperature ceramic substrate by the RF magnetron sputtering technology. The thickness of the thermocouple contacts is in the micron grade. The K-type film thermocouple can effectively fit the spacecraft surface and be used for high-temperature transient measurement on the spacecraft surfaces. Physical test verifies that the measuring temperature of this K-type film thermocouple can reach as high as 800℃, and the relative measurement error is within ±0.5％. It can well fulfill the high-temperature transient measurement requirement of recoverable spacecrafts' surfaces.关键词
