超声风速温度仪的误差分析与检定方法研究

Error Analyzes and Calibration Method of Ultrasonic Wind and Temperature Monitor

根据超声风速温度仪的原理,分析了其测量误差的主要来源,进而总结出两个主要误差项。针对这两个主要误差项提出了一种快速的误差检定方法,理论上只需两次测量即可完成对风速温度的误差检定。同时分析了不同温度条件下相对湿度对超声风速温度仪测温的影响,并给出了相关结论。

Basing the principle of the ultrasonic wind and temperature monitor, The main cause of the error measurement was analyzed and concluded two main error terms. Theoretically, measurement in twice can completely calibrate the measurement error of the wind speed and the temperature. Then the effect of relative humidity upon ultrasonic wind and temperature monitor under different temperature was also discussed.
