Ultrasonic Thickness Gauge Principle-ultrasonic sensor application and circuit

ShenZhen OSENON Technology Co.,Ltd | Updated: May 03, 2018


Ultrasonic Thickness Gauge is based on the principle of ultrasonic sensor's pulse reflection thickness measurement, when the ultrasonic pulse emitted by the probe through the measured object reaches the material interface, the pulse is reflected back to the probe through the precise measurement of ultrasonic propagation time in the material to be determined The thickness of the material is measured. Any material that allows ultrasound to propagate inside it at a constant speed can be measured using this principle.

Ultrasonic Thickness Gauge uses the latest high-performance, low-power microprocessor technology, based on the principle of ultrasonic measurement, can measure the thickness of metal and other materials, and can measure the sound speed of the material. It is possible to measure the thickness of various pipes and pressure vessels in production facilities, monitor the degree of thinning after they are etched during use, and also make accurate measurements of various plates and various processed parts.


Ultrasonic Thickness Gauge mainly consists of a host and a ultrasonic sensor probe. Host circuit includes transmitter circuit, receiver circuit and count display circuit. The high-voltage shock wave generated by the transmitter circuit excites the probe and generates ultrasonic pulse wave. The pulse wave is received by the receiver circuit after being reflected by the dielectric interface. After being counted and processed by the single chip microcomputer, the pulse wave The liquid crystal display shows the thickness value, which is mainly based on the propagation speed of the sound wave in the sample multiplied by half the time passed through the sample to obtain the thickness of the sample.


Due to the convenience of ultrasonic processing and good directionality, ultrasonic technology measures the thickness of metal and non-metal materials, which is fast and accurate, and free of pollution. Especially in the case where only one side can be touched, the superiority can be displayed. , Widely used in various plate, pipe wall thickness, boiler container wall thickness and local corrosion, rust, so the metallurgy, shipbuilding, machinery, chemicals, power, atomic energy and other industrial sector product inspection, the safe operation of the equipment And modern management plays a major role.

Ultrasonic cleaning and ultrasonic thickness gauges are only part of the application of ultrasound technology. There are many other areas that 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 applied more and more widely in all walks of life.
