本文介绍了用热电堆测量风洞内“不均匀温度场”平均温度的方法.将热电堆各测量端均匀地、等距地也分布于风洞断面,用电位差计一次测量就可测得其温度.它具有国内用铜电阻网测量所没有的优点.试验实践表明,热平衡误差有明显的改善.文中还简要地介绍了热电堆的制作与校验方法,以及应注意消除的几项测量误差. In this paper, the method of measuring the average temperature of “inhomogeneous temperature field” in a wind tunnel by using thermopiles is introduced, and the measuring ends of the thermopile are evenly and equidistantly distributed in the wind tunnel section. Get its temperature.It has the advantages of domestic copper resistance network measurement.Experimental practice shows that the thermal balance error has been significantly improved.This paper also briefly introduced the thermopile manufacturing and verification methods, and should pay attention to the elimination of several Measurement error.
