基于雷诺准则的测温偏差压力工况修正方法

Pressure Working Condition Correction Method for Temperature Measuring Deviation Based on Reynolds Criterion

提出了一种温度传感器测温偏差校准结果的压力工况修正方法,并以某裸露式温度传感器为例,进行了测温偏差的压力工况修正。根据雷诺准则,通过改变马赫数的方式来替代压力的改变,对测温偏差的计算修正结果进行了验证。结果表明,计算修正结果与试验数据比较接近,所提出的压力工况修正方法,可以为常压条件下该型温度传感器的测温偏差校准结果提供修正的依据,同时也为其它类型温度传感器的压力工况修正提供了参考。

A pressure working condition correction method for temperature measuring deviation calibration results of temperature sensors is proposed in this paper. As an example,temperature measuring deviation of a certain bare-typed temperature sensor is corrected. According to Reynolds criterion,calculated correction results of temperature measuring deviation are validated by the method which replaces change of pressure by that of Mach number. The results show that calculated correction results are near experiment data,and the proposed correction method can not only provide foundation for this type of temperature sensors,but also give reference for other types of temperature sensors.
