Abstract

The invention discloses an X-ray thickness gauge probe comprising a metal shell body which is internally provided with a gas ionization chamber, a preamplifier board, and a high-voltage module. The front end of the gas ionization chamber is provided with a window. The gas ionization chamber is connected with the preamplifier board. The high-voltage module is electrically connected with the gas ionization chamber. The preamplifier board is provided with a high-power and low-noise operational amplifier module. The probe further comprises a shielding device which is fixedly arranged outside the window. The probe is simple in structure principle, and can quickly detect the intensity of X-rays penetrating a steel board. The adopted high-power and low-noise operational amplifier module can stably amplify weak signals, and is of low distortion. In addition, as the shielding device is arranged outside the window, electromagnetic interference is prevented, and the accuracy of detection is improved.

Description

technical field [0001] The invention relates to the technical field of thickness gauge probe structures, in particular to an X-ray thickness gauge probe. Background technique [0002] Coating Thickness Gauge can non-destructively measure the thickness of non-magnetic coatings on magnetic metal substrates and the thickness of non-conductive coatings on non-magnetic metal substrates. The coating thickness gauge has the characteristics of small measurement error, high reliability, good stability, and easy operation. It is an indispensable testing instrument for controlling and ensuring product quality. It is widely used in manufacturing, metal processing, chemical industry, Commodity inspection and other testing fields, and the probe of the coating thickness gauge is the most important part, which affects the measurement efficiency and measurement accuracy. The existing thickness gauge probe has complex structure and poor anti-interference ability, which is easy to cause measu...
