The Principle of Ultrasonic Thickness Measurement Instrument

Ultrasonic thickness measurement instrument is based on the principle of ultrasonic pulse reflection for thickness measurement, when the probe transmitted ultrasonic pulses through the material object to be tested interface, the pulse is reflected back to the probe through the accurately measuring of ultrasonic propagation time in the material to determine the thickness of the material. All kinds of materials which can make the ultrasonic wave propagate at a constant speed can be measured by this principle. Ultrasonic thickness meter is mainly composed of two parts of the host and probe. The probe is mainly composed of piezoelectric ceramic elements. The basic principle of ultrasonic thickness measuring instrument: for thickness measurement is mainly based on the principle of ultrasonic pulse reflection, when the probe transmitted ultrasonic pulses through the material object to be tested interface, the pulse is reflected back to the probe through the precise measurement of ultrasonic propagation time in the material to determine the thickness of the material being tested. All kinds of materials which can make the ultrasonic wave propagate at a constant speed can be measured by this principle. According to the principle of the design of the ultrasonic thickness gauge can be a variety of plates and a variety of processing parts for accurate measurement.
