This will be explained in detail below.
The host is used for sending out a detection instruction;
the pulse oscillator is used for sending out an oscillating voltage according to the detection instruction;
the probe 2 is used for receiving the oscillation voltage and sending out ultrasonic pulses according to the oscillation voltage;
ultrasonic pulses sent by the probe 2 enter a material (a material to be detected) through an acoustic coupling medium (such as engine oil or water and the like) and are transmitted in the material, after the ultrasonic pulses meet the bottom surface of the material, the reflected pulses return to the probe 2 along the original path, and the acoustic coupling medium is smeared on the material to be detected when in detection;

1. thickness measurement principle:
the thickness of the material is determined by accurately measuring the time for which the ultrasonic pulse travels through the material. The ultrasonic pulse reflection method is characterized in that when ultrasonic waves encounter an interface formed by media with different acoustic impedances, a reflection phenomenon occurs, namely, reflected pulses transmitted back to a probe after ultrasonic pulse is sent comprise interface reflected pulses and bottom surface reflected pulses, and if the propagation time of the interface reflected pulses is t 1 (the time at which the probe 2 receives the reflected pulse from the interface 7, which can be recorded by the host), the travel time t of the bottom reflected pulse 2 (the time at which the probe 2 receives the reflected pulse from the bottom surface 8, which can be recorded by the host computer), the propagation time of the ultrasonic wave in the material is t-t 2 -t 1 (host according to recorded t 1 And t 2 T is calculated so that the final t can be sent to the display 3), and the thickness of the test sample is h ═ c × t based on the propagation velocity c of the ultrasonic wave in the material.
2.
