反射式γ射线测厚仪是一种从单测无损测量金属管壁、金属平板和容器等厚度的仪器。本文介绍的反射式γ射线测厚仪具有晶体化、电池供电、重量轻、体积小,放射源强度小使用安全、不要求被测物表面光洁、探头直接接触即可测量、操作简便和直接读数等特点。所以在石油、化工和火力发电等工业部门中都有应用。如用来检查金属材料和部件的厚度,检修时检查部件的腐蚀和磨损情况等。图1是仪器工作原理图。仪器由一手枪式探头和本体两部分组成。手枪式探头内装
Reflective gamma-ray thickness gauge is a non-destructive measurement from a single metal pipe wall, metal plate and container thickness of the instrument. This article describes the reflection of γ-ray thickness gauge with a crystal, battery-powered, light weight, small size, low-intensity radioactive sources safe to use, does not require the measured object surface smooth, the probe can be measured directly in contact with, easy to operate and direct reading Features. So in the petroleum, chemical and thermal power and other industrial sectors have applications. Such as used to check the thickness of metal materials and components, inspection parts inspection corrosion and wear conditions. Figure 1 is the working principle of the instrument. Instrument consists of a pistol probe and the body of two parts. Pistol probe built
