Coating thickness gauge and ultrasonic thickness gauge operation principles
Ultrasonic thickness gauges are divided according to their working principles: resonance method, interference method and pulse reflection method. Since the pulse reflection method does not involve the resonance mechanism and has no close relationship with the surface finish of the measured object, the ultrasonic pulse thickness gauge is the most popular instrument among users.
1 Working principle
The ultrasonic thickness gauge is mainly composed of two parts: the host and the probe. The host circuit includes three parts: transmitting circuit, receiving circuit, and counting and displaying circuit. The high-voltage shock wave generated by the transmitting circuit excites the probe to generate ultrasonic transmitting pulse waves. The pulse waves are reflected by the medium interface and received by the receiving circuit. After counting and processing by the single-chip computer, the thickness value is displayed on the liquid crystal display.
The HT series ultra-wave thickness gauge operated by our factory is a pocket-sized intelligent measuring instrument with low power consumption and low lower limit developed by single-chip technology on the basis of adopting advanced technology at home and abroad.
2 Thickness Gauge Applications
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 occasions where only one side is allowed to be touched, which can show its superiority.
It plays a major role in equipment operation and modern management.
Ultrasonic cleaning and ultrasonic thickness gauge are only part of the application of ultrasonic technology, and there are many fields that can be applied to ultrasonic technology. Such as ultrasonic atomization, ultrasonic welding, ultrasonic drilling, ultrasonic grinding, ultrasonic liquid level gauge, ultrasonic level gauge, ultrasonic polishing, ultrasonic cleaning machine, ultrasonic motor and so on. Ultrasonic technology will be more and more widely used in all walks of life.
