A pulse (emission wave) generated by the high-frequency pulse generator is applied to the ultrasonic sensor probe to excite the piezoelectric crystal to oscillate to generate ultrasonic waves. Ultrasonic waves propagate to the inside of the workpiece at a certain speed. A part of the ultrasonic wave

Ultrasound refers to mechanical waves with a frequency higher than 20 kHz. In order to use ultrasonic waves as a detecting means, it is necessary to generate ultrasonic waves and receiving ultrasonic waves. The device that performs this function is an ultrasonic sensor, which is customarily called a

One can hear that the sound is generated by the vibration of the object. Its frequency of transducer for distance is in the range of 20HZ-20KHZ, the ultrasonic wave is more than 20KHZ, and the infrasound wave is lower than 20HZ. Commonly used ultrasonic frequencies are tens of KHZ-tens of MHZ. Since

The core of the underwater acoustic transducer is a piezoelectric wafer in its outer casing, and there are many kinds of materials constituting the wafer. The size of the wafer, such as diameter and thickness, varies, so the performance of each probe is different and its performance must be known be

Hardware circuit designThe square wave of 40 kHz transducer fishfinders ultrasonic sensor is programmed by the single chip , output by the P3.6 port, and then the ultrasonic transmitting probe is used to transmit the ultrasonic wave through the amplifying circuit. After the emitting ultrasonic wave
