矿浆浓度的超声测量

Ultrasonic Surveying of the Pulp Density

本文介绍一种把超声波在水中传播速度的测量应用于浮选法的矿浆浓度测量,它能适时测出浓度并进行过程控制。它是利用一个高速上升的调制波去推动超声换能器,获得测量信号,并进行温度补偿。

This paper describes a kind of instrument which applies ultrasonic velocity measurement to surueying the pulp density and which surueys the pulp density and control itself opportunely,It is able to glue impetus to art acute ultraso- nic stransducer and to get the signal measurement and carry on the tempera- ture-compensation by using a sort of quick-rising,pulse modulation,
