煤浆一类悬浊液浓度的传感问题,是选煤自动化中的一个重要课题。本文利用实验结果探索了用超声波传感煤浆浓度的可能性,并提出了这种传感器的可能方案,以及用此方案在实验室测得的超声幅值与煤浆浓度之间的关系曲线。
Sensing the concentration of a slurry of coal slurry is an important issue in the automation of coal preparation. In this paper, the possibility of using ultrasonic wave to sense the concentration of coal slurry is explored. The possible scheme of this kind of sensor and the relationship between the ultrasonic amplitude and the concentration of coal slurry measured by this method in the laboratory are presented.
