利用γ射线连续测量料位

Continuous Material-level Metering by γ-ray

利用γ射线穿透性强 ,同时又可被介质吸收的特点 ,通过电子电路转换放大计数管吸收的穿透容器的γ射线 ,得到不同剂量γ射线所对应的电信号 ,运用以单片机为基础开发的智能仪表采集此信号 ,经运算显示不同剂量γ射线对应的容器内物料高度百分比值 ,并输出相应的标准信号 ,为闭环控制提供依据。

Utilizing the powerful penetrability of γ-ray as well as the feature ofγ-ray that it can be absorbed by medium, and by means of penetrating container absorbed by switching-amplifying-counting tube in electronic circuit to obtain corresponding electric signals with different dosage ofγ-ray, apply intelligent instrument developed and produced based on monolithic processor to collect these signals, indicate the height percent of materials in container corresponding with different dosage ofγ-ray after calculat...
