干躁曲线的实验测定是设计和选用干躁装置的依据,目前,常用的实验装置均用天平称量和秒表计时测定失水量,操作烦复,准确性差。本装置采用位移传感器作为检测失水量的检测元件,配以自记式电位差仪,自动连续地绘制干躁曲线,简化了操作,提高了实验精确度。 Drip curve experimental determination is the basis for the design and selection of dry-action device, at present, the commonly used experimental devices are measured with a balance and stopwatch timing of the loss of water, annoying the operation, accuracy is poor. The device uses a displacement sensor as the detection of water loss detection components, together with the self-recorded potential meter, automatically drawing a dry curve of impatience, simplifying the operation and improve the experimental accuracy.
