In the ultrasonic distance transducer,distance methods generally have a single-shot dual-receiving type, and it is also a sonic logging method. In terms of composition, there are mainly three sound systems, sound insulators and electronic circuits, and the sound system therein includes a transmitter and a receiver.
2.ultrasonic distance transducer, which belongs to ultrasonic transducer? In addition,the application of ultrasonic transducers are very extensive?
Ultrasonic distance transducer, which belong to ultrasonic transducers, are also unquestionable. Ultrasonic transducers, from the current point of view, are widely used in industries such as industry, agriculture, transportation, and medical.
3.On the ultrasonic distance transducer, what is its capacitance? In addition, its capacitance is mainly related to the parameters.
On the ultrasonic distance transducer, its capacitance mainly affects the matching of the transducer. The capacitance of the transducer, and its related parameters, mainly include the size of the piezoelectric ceramic sheet, the dielectric constant, and the capacitance of the cable. if its size is certain, then it is mainly on the dielectric constant.
4.About piezoelectric ceramic, what is its specific?
About piezoelectric disc element, which is a kind of electronic sounding component from a professional point of view,dielectric material of piezoelectric ceramic is placed in the two copper circular electrodes, and an AC audio signal is connected thereto, so that piezoelectric ceramic sheets will occur according to the frequency of occurrence of the signal, resulting in the corresponding vibrations. Therefore, according to its principle, it can be used in pronunciation electronic watches, electronic timepieces, timers, and toys.
5.About piezoelectric ceramic, do they have the positive and negative electrodes? How to judge?
About piezoelectric sensor for acoustic pickups, which have positive and negative electrodes, and this is what we all should know and understand. As for the judgment method, and simple, first draw two wires on the two poles, then use the current block of the multimeter to see the direction of the pointer swinging. If it is pendulum to the right, then the contact with the red pen is positive. On the contrary, it is the positive electrode that is in contact with the black test pen.
About the piezoelectric ceramic element sheets and metal chip, which are vibrated and audible under the excitation of an alternating electric field after bonding, but if they do not match the acoustic impedance of the air, the sound is small. And in DXP, it can be replaced with a small buzzer.
