Abstract
A sapphire fiber blackbody cavity transient high temperature sensor based on contact and contact-less integration are introduced.The blank-body cavity production and weak photoelectricity signal detection were analyzed.Finally, the testing results were also given.The experimental results show that after the new photo-electric detector and film material used, the temperature range and signal to noise ratio of the sensor was in-creased.The temperature sensor measuring range upper limit is greater than2000℃and the response time less than100ms.It can meet the temperature measurement required by the research and industrial production in some specific environment.
