| 摘 要： | 对美国GE露点仪测量性能进行了分析。结合GE露点仪使用过程中遇到的问题,总结了GE露点仪的探头选择、探头安装位置、气密性及流量控制等使用要求。以双压法湿度发生器作为标准装置,对GE露点仪进行了大量静态测试,结果表明:GE露点仪相对湿度测量值偏低;在低温条件下,测量误差较大且分散性较大;随着温度的降低,灵敏度明显降低,测量重复性变差,至-10℃时性能下降明显。该文研究内容,对于认识GE露点仪测量性能,保证其测试准确度和可靠性具有重要意义。

| Abstract: | The measuring performance of GE Dew Point Analyzer is studied. By studying the problems encountered in use, operating requirements, such as the choice of probes, the installation place of a probe, gas tightness, and control of flow, are summarized. Many static tests were conducted with the twopressure humidity generator as the standard. The results show that the relative humidity measured by GE Dew Point Analyzer is lower than that by the two-pressure humidity generator; for low temperature, the measurement error is larger and more dispersive. As temperature decreases, the sensitivity declines and the repeatability characteristic becomes worse. At -10 ℃, its performance decreases significantly. The findings are of significance for determining the measuring performance and improving the accuracy and reliability of Dew Point Analyzer. |
