A New Method of Measuring the Temperature of Rotary Wheel Disc

Based on the structural principle of the infrared detection technology and the temperature measure of rotary wheel. First of all, the type of infrared thermometer is selected according to the practical request of low or high temperature measure of rotary wheel disc. And then, the same point temperature of the turbine wheel disc of an engine is measured through infrared thermometer and thermoelectric couple in the heating status, and the measure results are compared, which dictates that the infrared thermometric system could achieve an upper detection precision and satisfy the practical engineering request.
