摘要
介绍采用便携式仪表进行在线测量热设备表面全热流的研究。该方法是用两台前置反射器辐射温度计以非接触方式实现的。分析了测量中的系统误差,对于200℃以上的表面全热流相对误差在4%以内。
The investigation of on-line measurement of the whole heat flow on the surface of heat equipment by using a portable instrument is introduced. The method is accomplished through non-contacting measurement by using two prereflecting radiation thermometers. The system accuracy of measurement is analyzed. The relative error of the whole heat flow of the surface above 200℃ is within 4%.
