Points for Attention in the Operation of Ultrasonic Thickness Gauge

Ultrasonic thickness gauge is a high-performance, low-power microprocessor technology. Based on the principle of ultrasonic measurement, it can measure the thickness of metals and other materials, and can measure the speed of sound of materials. It can measure the thickness of various pipes and pressure vessels in the production equipment, monitor the degree of thinning after they are corroded during use, and can also measure various plates and various processed parts.

Ultrasonic thickness gauge is based on the principle of ultrasonic pulse reflection for thickness measurement. When the ultrasonic pulse emitted by the probe reaches the material interface through the measured object, the pulse is reflected back to the probe. Measure the thickness of the material. This principle can be used to measure all kinds of materials that can make ultrasonic waves propagate in its interior at a constant speed.

Operation precautions
1. When conducting the test, pay attention to the metal magnetic properties and surface roughness of the standard sheet collectively should be similar to that of the test piece.　　
2. When measuring, pay attention to keeping the side head perpendicular to the surface of the sample.　　
3 Pay attention to the critical thickness of the base metal when testing. If it is greater than this thickness, the measurement will not be affected by the thickness of the base metal.　
4. When measuring, pay attention to the influence of the curvature of the test piece on the measurement. Therefore, it is unreliable when measuring on the curved surface of the test piece.　　
5. Before measuring, pay attention to whether other electrical equipment around will generate magnetic field, if it will interfere with the magnetic thickness measurement method.　　
6. When measuring, be careful not to measure at the inner corner and near the edge of the test piece, because the general thickness gauge is very sensitive to sudden changes in the surface shape of the test piece.
7. Keep the pressure constant during the measurement, otherwise it will affect the measured readings.　　
8. When testing, pay attention to the direct contact between the probe of the instrument and the test piece, so the ultrasonic thickness gauge is in the process of removing the attached material on the opposite side.
