Ultrasonic Thickness

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.

Ultrasonic Thickness

Ultrasonic thickness gauges are easy to operate and reliable, and can be used to measure a wide range of thicknesses and inspect all engineering materials. Supplementing the simple ultrasonic thickness gauges that present results in either a digital readout or as an A-scan with systems that enable correlating the measured values to their positions on the inspected surface to produce a two-dimensional (2D) thickness representation can extend their benefits and provide a cost-effective alternative to expensive advanced C-scan machines. In previous work, the authors introduced a system for the positioning and mapping of the values measured by the ultrasonic thickness gauges and flaw detectors (Tesfaye et al. 2019). The system is an alternative to the systems that use mechanical scanners, encoders, and sophisticated UT machines. It used a camera to record the probe’s movement and a projected laser grid obtained by a laser pattern generator to locate the probe on the inspected surface. In this paper, a novel system is proposed to be applied to flat surfaces, in addition to overcoming the other limitations posed due to the use of the laser projection. The proposed system uses two video cameras, one to monitor the probe’s movement on the inspected surface and the other to capture the corresponding digital readout of the thickness gauge. The acquired images of the probe’s position and thickness gauge readout are processed to plot the measured data in a 2D color-coded map. The system is meant to be simpler and more effective than the previous development.
