Composition and application fields of ultrasonic thickness gauge
The ultrasonic thickness gauge mainly consists of two parts: the main unit and the probe. The main unit circuit includes three parts: the transmission circuit, the connecting circuit, and the counting and display circuit. The low-voltage shock wave generated by the transmission circuit encourages the probe to generate ultrasonic emission pulse waves. The pulse waves are reflected by the dielectric interface and taken over by the connecting circuit. After being counted and processed by the microcontroller, the thickness value is displayed by the liquid crystal display device. It mainly obtains the thickness of the sample by multiplying the speed of sound waves in the sample by half of the time passing through the sample.
The ultrasonic thickness gauge stops thickness measurement based on the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe reaches the data interface of the measured object, the pulse is reflected back to the probe, and the thickness of the measured data is determined by accurately measuring the time of ultrasonic propagation in the data. All kinds of data that can make ultrasound waves propagate at a constant rate outside can be measured using this principle.
Because ultrasonic thickness gauges are easy to handle and have good directionality, ultrasonic technology can measure the thickness of metal and non-metal materials quickly, accurately, and pollution-free. Especially in places where only one front can be touched, it can better demonstrate its performance. It is widely used in various types of board, pipe wall thickness, boiler container wall thickness, and environments where parts are corroded and rusted. It can also measure PVC/PE pipes, laminated glass, multi-layer materials, and stacked materials. It plays an important role in the safe operation and modern management of equipment through product inspection in various industrial sectors such as metallurgy, shipbuilding, machinery, chemical industry, power, and atomic energy
