Introduction To The Principle Of Handheld Ultrasonic Thickness Gauge

The principle of the handheld multifunctional ultrasonic thickness gauge mainly adopts the principle of pulse reflection ultrasonic thickness measurement. The method is to send short ultrasonic pulses into the object. When it encounters the boundary of the object, it returns to get an echo and measures the ultrasonic pulse passing through the object. The time interval required for the test piece, and then the thickness of the piece under test is calculated based on the propagation speed of the pulse in the piece under test.
The thickness D of the tested piece can be calculated by the following formula: D=VT/2(1)
In the formula, V is the speed of sound in the material being tested, and T is the time 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 works in pulse mode, making it easier to implement on the instrument. It is also easy to achieve small size, fast speed, high precision and low power consumption.
