Ultrasonic sensor Ultrasonic receiver transmitter is mainly composed of piezoelectric chips, both can launch ultrasound, you can also receive ultrasound.
Small power ultrasonic receiver transmitter for detection.
It has many different structures, can be divided into straight probe (oblique wave), oblique probe (shear wave), surface wave probe (surface wave), Lamb wave probe (Lamb wave), dual probe (a probe reflection, a probe to receive) and many more
Ultrasonic receiver transmitter Design principles.
Ultrasonic sensor is the use of ultrasonic characteristics of the development of the sensor. Ultrasound is a mechanical wave whose vibration frequency is higher than that of sound wave. It is generated by the vibration of the transducer chip under the excitation of voltage. It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, Communication and other characteristics. Ultrasound on liquid, solid penetration ability, especially in the sun opaque solid, it can penetrate the depths of tens of meters.
Ultrasonic encountered impurities or interface will produce a significant reflection of reflected into an echo, hit the living body can produce Doppler effect. Therefore, ultrasonic testing is widely used in industrial, national defense, biomedical and other aspects of ultrasound as a means of detection, must produce ultrasound and receive ultrasound. The device that performs this function is an ultrasonic sensor, customarily called an ultrasonic transducer, or an ultrasonic probe.
