The ultrasonic thickness gauge measures thickness based on the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the material interface, the pulse is reflected back to the probe to determine the object being measured by accurately measuring the time it takes for the ultrasonic wave to propagate in the material.
Measure the thickness of the material. This principle can be used to measure various materials that can allow ultrasonic waves to propagate inside them at a constant speed.
The ultrasonic thickness gauge adopts the latest high-performance, low-power microprocessor technology and is based on the principle of ultrasonic measurement. It can measure the thickness of metal and various other materials, and can also measure the sound speed of the material. The thickness of various pipes and pressure vessels in production equipment can be measured to monitor the degree of thinning caused by corrosion during use. It can also accurately measure various plates and various processed parts.
The ultrasonic thickness gauge mainly consists of two parts: the host computer and the probe. The host circuit includes three parts: a transmitting circuit, a receiving circuit, and a counting display circuit. The high-voltage shock wave generated by the transmitting circuit excites the probe and generates an ultrasonic transmitting pulse wave. The pulse wave is reflected by the medium interface and is received by the receiving circuit. After counting and processing by the microcontroller, The LCD displays the thickness value, which is mainly based on the propagation speed of the sound wave in the sample multiplied by half of the time it takes to pass through the sample to obtain the thickness of the sample.
