Description

technical field [0001] The invention relates to an ultrasonic thickness gauge, in particular to an ultrasonic thickness gauge with a temperature detection function. Background technique [0002] Ultrasound is a sound wave with a frequency higher than 20,000 Hz. It has good directionality, strong penetrating ability, and is easy to obtain concentrated sound energy. Because of its convenient handling and good directivity, it is often used to measure various The wall thickness of plates and pipes, the wall thickness of boiler vessels and their local corrosion and rust conditions play a major role in the safe operation of equipment and modern management. Ultrasonic thickness measurement is based on the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the interface of the material, the pulse is reflected back to the probe. The thickness of the material. When propagating in a solid, temp...

AI Technical Summary

Problems solved by technology

When propagating in a solid, temperature, stress, and the uniformity of material and composition are important factors affecting the speed of ultrasonic propagation. Therefore, when measuring the workpiece, when the stress, material and composition factors remain unchanged, once there is a temperature change , the ultrasonic propagation speed will change accordingly, and the accuracy of ultrasonic thickness measurement will be greatly reduced.
