新研动态比对标准器及其温湿测量特性研究

Study of New Dynamic Comparison Standard Device and Its Measurement Characteristics for Temperature and Humidity

为了研究某新研制动态比对标准器样机温湿度测量性能,进行了多次静态测试和一次为期三个月的动态比对试验。本文根据试验数据,分别对样机温湿测量模块的静态性能、干湿球配对测量性能、动态性能进行评估,并统计了样机动态测量结果与现有TFS-1通风干湿表测量结果的相关系数,比较了两者的防辐射性能。结果表明:被试样机温湿度测量动静态性能良好,与TFS-1通风干湿表测量结果相关性较高,防辐射性能相当,因此,新研制的动态比对标准器基本满足作为动态比对标准器的要求。

In order to study the prototype performance of temperature and humidity measurement of a new dynamic comparison standard de- vice, a number of static tests and a three-month dynamic comparison trial were conducted. Based on the test data, this paper evaluates static per- formance, wet and dry bulb paired measurement performance, and dynamic performance of temperature and humidity measuring modules respec- tively in a prototype, calculates the correlation coefficient of dynamic measurement results between the prototype and the TFS-1 ventilation psy- chrometer, and compares the radiation resistant performance of both. The results show that the prototype in test has a good dynamic and static performance in both temperature and humidity measurement, a high coorelation with the TFS-1 ventilation psychrometer, and an equivalent radia- tion resistant performance. The new dynamic comparison standard device can meet the relevant requirements.
