一、概述 FT-1914型核密度计属于放射性工业仪表,是一种NIM插件结构和积分测量方式的密度计,广泛用于测量管道及槽内介质的密度。由于它与被测对象不接触,可以解决其它检测技术无法解决的某些测量难题,因而在石油、化工、煤炭、冶金、矿业、电力、造纸、食品以及军工等部门得到了广泛的应用。它能显示密度,并提供输出信号,以便记录和实现工艺过程被测参数的自动控制。也可与流量计和FH-1111数据采集微处理机配合,组成FT-1912型微机产量计,实现自动打印各种介质的累计体积或重量产量。二、主要技术指标 1.测量范围:密度0~3g/cm~3,或质量厚度(密度ρ×管径D)(10~100)g/cm~2。实
I. Overview FT-1914-type nuclear density meter is a radioactive industrial instrumentation, is a NIM plug-in structure and integral measurement of the density meter, widely used in measuring the density of the pipeline and tank media. Because it is not in contact with the measured object, it can solve some measurement problems that other detection technologies can not solve. Therefore, it has been widely used in petroleum, chemical, coal, metallurgy, mining, power, papermaking, food and military industries. It displays density and provides output signals for recording and automatic control of measured parameters of the process. Also with the flowmeter and FH-1111 data acquisition microprocessor with the composition of FT-1912 microcomputer production meter, automatically print a variety of media cumulative volume or weight production. Second, the main technical indicators 1. Measuring range: the density of 0 ~ 3g / cm ~ 3, or the quality of the thickness (density ρ × diameter D) (10 ~ 100) g / cm ~ real
