Difference analysis of the working principles of ultrasonic flaw detector and ultrasonic thickness gauge
The ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument that can quickly, conveniently and non-destructively inspect the workpiece.
Detection, location, evaluation and diagnosis of various internal defects. It can be used both in the laboratory and on engineering sites. Widely used in boilers, pressure vessels, aerospace, aviation, electric power, petroleum, chemical industry, offshore oil, pipelines, military industry, shipbuilding, automobiles, machinery manufacturing, metallurgy, metal processing industry, steel structures, railway transportation, nuclear power, universities, etc. industry.
Ultrasonic thickness gauge is also a thickness gauge. It mainly uses the principle of ultrasonic pulse reflection method to conveniently and quickly measure the thickness of materials and objects to achieve the most basic detection function. It can be widely used in petroleum, chemical industry, metallurgy, shipbuilding, aviation, aerospace and other fields.
Working principle of ultrasonic flaw detector:
First of all, ultrasonic flaw detector is a technology that when ultrasonic waves propagate in the material to be detected, the acoustic properties and internal tissue changes of the material have a certain impact on the propagation of ultrasonic waves. It can understand the material properties and structural changes by detecting the degree and condition of the impact of ultrasonic waves. It's called ultrasonic testing. The ultrasonic flaw detector is an instrument specially designed for industrial non-destructive testing. It can detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) inside the workpiece quickly, conveniently, non-destructively and without damage. It can be used both in the laboratory and on engineering sites. Although ultrasonic flaw detectors can be used for thickness measurement, the software interface is only for flaw detection and determination.
Working principle of ultrasonic thickness gauge:
The ultrasonic thickness gauge measures thickness based on the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe reaches the material interface through the object to be measured, the pulse is reflected back to the probe and the measured time is determined by measuring the propagation time of the ultrasonic wave in the material. The thickness of the material. The ultrasonic thickness gauge uses high-performance, low-power microprocessor technology. Based on the principle of ultrasonic measurement, it can accurately and quickly measure the thickness of metals and various other materials, and can measure the sound speed of the material; it can also measure The thickness of various pipes and pressure vessels in production equipment is measured to monitor the degree of thinning caused by corrosion during use. It can also be used to measure various plates and various processed parts.
