Ultrasonic Wall Thickness Gauge

【Common Issues in Practical Operation of Ultrasonic Coating Thickness Gauges​】 The ultrasonic coating thickness gauge is a widely used tool, with the advantage of non-destructive measurement of coating thickness. However, to obtain accurate data, users need to know what factors can affect the accuracy? These factors are also applicable to pipe thickness tester and UT thickness tester, as their core is ultrasonic technology. Improper probe contact is the first important factor: either the pressure is too strong or the pressure is unevenly applied. For example, for pipe thickness tester, the pipe surface is curved, making it more difficult to stabilize the probe, and the error will be more obvious. At this time, a curved probe adapter needs to be used to solve the contact problem. Environmental factors can also interfere with the measurement. There are dirt on the surface: if the substrate surface is stained with dust or oil, the sound wave will be blocked and the measurement will be…
