Knowledge of Ultrasonic thickness gauge
Ultrasonic Thickness Gauge幸运飞艇计划软件免费版 uses the latest high-performance, low-power microprocessor technology. Based on the principle of ultrasonic measurement, it can measure the thickness of metal and other materials, and can measure the sound velocity of materials. Thickness measurement can be carried out on various pipes and pressure vessels in production equipment, to monitor the degree of corrosion after corrosion in use, and to accurately measure various plates and various machined parts.
Ultrasonic thickness gauges are mainly composed of two parts: the main unit and the probe. The host circuit includes a transmitting circuit, a receiving circuit and a counting display circuit. The high-voltage shock wave generated by the transmitting circuit excites the probe to generate an ultrasonic transmitting pulse wave. The pulse wave is received by the receiving circuit after being reflected by the medium interface, and is processed by the single-chip microcomputer. The liquid crystal display displays the thickness value, which is mainly obtained by multiplying the propagation speed of the acoustic wave in the sample by half the time passed through the sample.
Due to the convenience of ultrasonic treatment and good directivity, ultrasonic technology measures the thickness of metal and non-metallic materials, which is fast, accurate and non-polluting, especially in the case where only one side can be touched. It is widely used in various plate, pipe wall thickness, boiler vessel wall thickness and local corrosion and rust. Therefore, it is responsible for product inspection of metallurgy, shipbuilding, machinery, chemical, electric power, atomic energy and other industrial sectors. And modern management plays a major role.
Ultrasonic cleaning and ultrasonic thickness gauges are only part of the application of ultrasound technology, and many areas can be applied to ultrasound technology. Such as ultrasonic atomization, ultrasonic welding, ultrasonic drilling, ultrasonic grinding, ultrasonic level gauge, ultrasonic level gauge, ultrasonic polishing, ultrasonic cleaning machine, ultrasonic motor and so on. Ultrasonic technology will be used more and more widely in all walks of life.

2, 30mm multi-point measurement method: When the measured value is unstable, take a measurement center as the center, and make multiple measurements in a circle with a diameter of about 30mm, taking the minimum value as the measured workpiece thickness value.
幸运飞艇计划软件免费版The number of measurements is increased around the specified measurement point, and the thickness variation is represented by an equal thickness line.
幸运飞艇计划软件免费版Continuous measurement along a specified route using a single point measurement with an interval of no more than 5 mm.
Mark the grid in the specified area and record the thickness by point. This method is widely used in corrosion monitoring of high pressure equipment and stainless steel lining.
