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.
