本文介绍一种用氯化锂露点测头作为传感器,采用半导体致冷方法的连续测量常温低湿空气露点温度的仪器.测量范围:露点温度0～-40℃,空气温度0～30℃。研制的样机经过标定和现场试验已投入实际使用。本文还在理论上进行了一些探讨.
In this paper, a device for measuring the dew point of air at room temperature and humidity is continuously measured by using the dew point probe of lithium chloride as the sensor and the semiconductor cooling method. The measuring range is 0 ~ -40 ℃ with dew point and 0 ~ 30 ℃ with air temperature. The prototype has been put into practical use after calibration and field test. This article also made some theoretical discussions.
