用于水泥厂的新型同位素料位计的研制及应用

DEVELOPMENT AND APPLICATIONS OF NEW TYPE ISOTOPE LEVEL METERS FOR CEMENT FACTORYS

根据目前国内现有的用于水泥厂料位检测与控制的开关式同位素料位计的现状，研制了一种新型同位素料位计。此料位计采用数显电路、计数检测控制电路及双路控制输出，反应时间小于１ｓ。在探测器电路中采用猝灭电路，延长了Ｇ－Ｍ计数管的使用寿命。现场应用表明，该料位计具有反应灵敏、抗干扰能力强、工作可靠、调试方便等优点，并具有较好的经济效益与社会效益。

According to the situation of current domestic switch isotope level meters used for the level measurement and control in cement factorys, a new type isotope level meter is developed. The level meter includes digit display circuit, count detection and control circuit and two ways control export, its response time is less than 1 second. The quenching circuit in the detector lengthens the using lifespan of G M counter. The application in the factorys indicates that the level meter has the advantages of sensitive,strong anti disturbance, reliable and adjustment simplicity. The use of the level meter can make the better economy benefit and society benefit.
