摘要

为提高热膜风速计在非恒温流场状况下的测量精度

提出了一种温度自动校正方案。通过对热膜探头的温度特性分析

提出采用铂电阻作为热膜风速计的温度补偿元件。经温度校正后

热膜风速计零点温度漂移可以达到4.8×10-2%FS/℃

灵敏度温度漂移可以达到-1.0×10-2%FS/℃。试验结果表明:利用铂电阻对热膜风速计进行温度自动校正取得了较为理想的效果。

Abstract

In order to improve the measurement precision for hot-film anemometer（HFA） in nonisothermal flow field

a new automatic correction method is presented.Through analysis of hot-film probe temperature characteristic

platinum resistance is used as hot-film anemometer temperature compensation sensor.After automatic temperature calibration

zero temperature drift of HFA can reach 4.8×10

-2

%FS/℃ and sensitivity temperature drift may achieve-1.0×10

-2

%FS/℃.The experiment results show that the HFA which uses the platinum resistance as temperature automatic calibration could obtain an ideal effect.
