同位素料位计是一种非接触式的检测仪表,可对密闭容器内的料位或液伍进行连续自动检测,因而广泛适用于化肥、化工、冶金、水泥等厂矿及高温、高压、强腐、剧毒等环境恶劣场所的料位检测与控制.目前我国使用的同位素料位计,大都采用盖革计算管作探头,不仅探测效率低,而且不能适用于较大的设备和管壁较厚的设备,使应用受到限制.为了适应生产实际的需求,河南省科学院同位素研究所的科研人员,通过近一年的努力,采用闪烁探头、集成电路和对数表电路,研制成FDL—1型同位素料位计.经通许、郑州化肥厂在氨分
Isotope level meter is a non-contact detection instrument that can continuously and automatically detect the material level or liquid in a closed container. It is widely used in chemical industry, chemical industry, metallurgy, cement and other factories and mines and high temperature, high pressure, strong rot , Toxic and other harsh environment of the site level detection and control.At present, the isotope level gauge used in China, most commonly used Geiger calculation pipe for the probe, not only low detection efficiency, and can not be applied to larger equipment and wall thicker Of the equipment, the application is limited.In order to meet the actual production needs, Henan Academy of Sciences Institute of isotope researchers, through the efforts of the past year, the use of scintillation probe, integrated circuit and logarithmic meter circuit, developed FDL-1 type Isotope level meter.
