Abstract
PURPOSE: To simplify calculation and improve response in measuring the thickness of a plate through absorption of radiation, by previously making a table of real counting rates for the thickness of the plate and determining the plate thickness through rectilinear interpolation between two real counting rates nearest to measured ones.
CONSTITUTION: A shielding container 2, in which a radiation source is housed, and a detector 3 employing a photoelectric multiplier or the like are provided at both the sides of a measured piece 1 such as a steel plate. The output pulses of a detector 3 based on radiation transmitted through the measured piece are changed into a calculable signal by a signal converter 7. The signal is applied to a calculation processor 8. The pulse signal and a temperature signal, which is detected by a temperature detector 4 and applied to the processor 8 through the signal converter 7, are calculated and processed to be indicated on a display recorder 9. A table of counting rates, which is previously made, is used for the counting part of the characteristic curve of a transmitted radiation output corresponding to the thickness of the measured piece 1. The thickness is determined by rectilinear interpolation. According to this method, calculation is simplified and response is improved.
