Since ultrasonic wave directive property is strong, energy expenditure is slow, and farther out, thus ultrasonic wave is frequent for the distance propagated in the medium
It can be realized by ultrasonic wave for the measurement of distance, such as rangefinder and fill level measuring device.It is past using ultrasound examination
Toward it is relatively rapid, conveniently, calculate it is simple, be easy to accomplish real-time control, and industrial requirements can be reached in terms of measurement accuracy.
In order to study and utilize ultrasonic wave, people to design and be made many supersonic generators.Generally speaking, surpass
Sonic generator can be divided into two major classes：One kind is with electrically generating ultrasonic wave, and one kind is mechanically to generate ultrasound
Wave.Include electrically piezo-electric type, magnetostriction type and power type etc.；Mechanical system has jar (unit of capacitance) system flute, the liquid whistle and air-flow siren
Deng.The frequency of ultrasonic wave, power and acoustic wave character caused by them are different, thus purposes is also different.At present compared with
For the most commonly used is piezoelectric-type ultrasonic wave producers.
Piezoelectric-type ultrasonic wave producer is actually using the resonance of piezo-electric crystal come work.Inside supersonic generator
There are two piezoelectric chip and a sounding boards.When his the two poles of the earth applying pulse signal, frequency is equal to the intrinsic of piezoelectric chip and shakes
When swinging frequency, piezoelectric chip will resonate, and drive resonance panel vibration, just generate ultrasonic wave., whereas if between two electrodes
Compressing piezoelectric chip is vibrated when sounding board receives ultrasonic wave, converts mechanical energy into electric signal by non-applied voltage,
At this moment he just becomes ultrasonic receiver.
