【Abstract】 This paper introduces the development of nuclear radiation thickness guage of non-contacting continous on- line measurement, which is widely suitable for mangle production line of sheet-metal strip or thin-sheet materials. By the principles of radiation penetration and one chip computer technology, the gauge will succeed in dealing with measurement data and realizing some special functions, such as numerical display and output of absolute thickness values and deviation values, direct current display and output of deviation, and automatic identification and whole automatic calibration to measurement states, as well as keyboard index of working conditions within the machines.更多还原
