Description

Technical Field

[0001] The utility model relates to the field of measuring instruments, in particular to an ultrasonic thickness gauge. Background Art

[0002] Ultrasonic thickness gauge is a device that uses the ultrasonic principle to measure thickness. Its working principle is that when the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the material interface, the pulse is reflected back to the probe, and the thickness of the material to be measured is determined by accurately measuring the time it takes for the ultrasonic wave to propagate in the material. This thickness gauge has a wide range of applications and can measure the thickness of any good conductor of ultrasonic waves, such as metals, plastics, ceramics, glass, etc. In the field of industrial production, ultrasonic thickness gauges are often used to accurately measure materials or parts, such as plates, pipes, pressure vessels, etc. In addition, it can also monitor the degree of thinning of various pipes and pressure vessels in production equipment after corrosion during use, thereby ensuring the safe operation of the equipment. .

[0003] When using an ultrasonic thickness gauge, a coupling agent is also required. The coupling agent can apply a layer of sound-permeable medium between the probe and the surface of the object to be measured, which can remove air, improve signal transmission effect, reduce signal interference, protect the probe and lubricate. In the prior art, the coupling agent tank and the ultrasonic thickness gauge are two separate tools. To complete accurate thickness measurement, the two tools need to be used separately, which results in the inspectors needing to carry a large number of tools, which is very inconvenient.
