Principle of Portable Ultrasonic Thickness Gauge

Abstract: 便携式超声波测厚仪利用脉冲反射超声波原理来测量材料厚度。其工作原理是通过测量超声波脉冲在测试件中的传播时间来计算厚度。公式D = VT/2中,D为试件厚度,V为材料中的声速,T为超声波脉冲在材料表面间来回传播的时间。该技术以其简单、易于实现的小尺寸、高速、高精度和低功耗特点,广泛应用于厚度测量。

The principle of the portable ultrasonic Thickness Gauge mainly adopts the principle of pulse reflection ultrasonic thickness measurement. The time interval required for the test piece, and then the thickness of the test piece is obtained according to the propagation speed of the pulse in the test piece.

The thickness D of the test piece can be calculated by the following formula: D=VT/2(1), where V is the speed of sound in the material to be tested, and T is the time required for the ultrasonic pulse to travel back and forth between the two surfaces of the test piece .

The principle of pulse reflection ultrasonic thickness measurement is simple, and it works in pulse mode, which makes it easier to implement on the instrument, and it is easy to realize small size, high speed, high precision and low power consumption.
