摘要
介绍了红外测温仪的工作原理和用红外测温技术测量旋转轮盘温度的结构原理。从旋转轮盘需要低温测量和高温测量的实际要求选取了合适的红外测温仪型号。对某型发动机涡轮盘在加温状态的同一点温度分别采用红外测温仪和热电偶进行了测量。结果表明,红外测温系统可以达到较高的测量精度,可满足工程实际的需要。
The working principle of infrared thermometer and the structural principle for measuring the temperature of rotary wheel disc through infrared thermometric technology are introduced.The type of infrared thermometer is selected according to the practical request of low or high temperature measure of rotary wheel disc.The same point′s temperature of the turbine wheel disc of an engine is measured through infrared thermometer and thermoelectric couple in the heating status.The measure results are compared,which dictates that the infrared thermometric system could achieve an upper detection precision and satisfy the practical engineering request.
