A new type of thin film heat transfer gage with high spatial resolution and fast response is proposed for the measurement of heat transfer rate in wind tunnels with long flow duration. The principle of the sensor is based on measuring the temperature gradient across a thin, heat resistant layer of SiO with two, thin film resistance thermometers on its upper and lower surfaces. These thin films and heat resistant layer are deposited by vacuum evaporation technique. The design consideration, the accuracy of the sensor, and the calibration technique are discussed.
