Research of Ultrasonic Thickness Measurement Method Based on the Pulse Reflection Type

Abstract:

The thickness measurement and monitoring of all kinds of equipment and parts, especially making general investigations on the thickness of boiler, pressure vessel and pipelines regularly, monitoring their thinning after corrosion in the process of using, and ensuring the safety production have attracted more and more attention among the companies. Based on the thickness measurement principle of pulse reflection type ultrasonic, the measurement method of the steel plate thickness was studied, and AVR Atmega16 single chip microcomputer as control chip was used. The analysis and comparison of ultrasonic transmitting circuit, receiving circuit, amplifying circuit, LCD display circuit, keyboard circuit, communication circuit, counter 232 AVR Atmega16 line were also included. The performance of this system regarding the steel plate as sample was tested, and then the data and the causes of measurement error were presented.
