Description

technical field [0001] The invention relates to the technical field of ultrasonic probes, in particular to an ultrasonic measuring probe that is convenient for high-temperature online detection. Background technique [0002] Ultrasonic measuring probe is a non-destructive testing method used to measure materials and workpieces and use an ultrasonic detector as a display method. Ultrasonic measurement is to use many characteristics of ultrasonic waves (such as reflection and diffraction) to determine whether the interior and surface of the tested material and workpiece are There are defects. In the field of industrial testing, non-destructive testing has been widely used because it does not damage or affect the performance of the tested object. [0003] Ultrasonic nondestructive testing is a method that is widely used at present, and the probe used for ultrasonic measurement is generally composed of piezoelectric ceramics. Due to the material characteristics of the piezoele...

AI Technical Summary

Problems solved by technology

Due to the material characteristics of the piezoelectric ceramic itself, its Curie temperature point is low (about 120°C), and it is not convenient to work in a working environment with too high temperature, which is easy to affect the working measurement results, and it is easy to cause the probe to be damaged and unable to work. , and at present, when the probe is measured in a high-temperature environment, most of them use a cooling device to dissipate heat. However, the existing cooling equipment is relatively simple, and its use effect is poor. The attenuation of the ultrasonic signal affects the normal detection of the signal, and the probe cannot be heat-dissipated in many ways, resulting in poor practicability. For this reason, we provide an ultrasonic measuring probe that is convenient for high-temperature online detection to solve this problem
