Ultrasonic sensor KS-1640H12ATR

ultrasonic sensor also known as ultrasonic probe, ultrasonic transducer.

Ultrasonic sensor is a kind of sensor which is developed by using the characteristics of ultrasonic wave. Ultrasonic waves are sound waves with frequencies higher than 20KHZ,

Ultrasound is named because its lower frequency is approximately equal to the upper limit of human hearing.

Ultrasonic wave is a kind of mechanical wave whose vibration frequency is higher than sound wave. It is generated by the vibration of ultrasonic piezoelectric ceramic chip under the excitation of voltage.

It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, strong penetration ability, and can become a ray and directional propagation.

Ultrasonic sensors also have high sensitivity, small size, light weight, robustness, high precision, good consistency, low power consumption and in polluted environments

Advantages of use. Because the ultrasonic directivity is very strong, the ultrasonic sensor emits ultrasonic waves in a certain direction and returns immediately when it encounters obstacles on the way.

It is easy to calculate the distance from the launching point to the obstacle by the principle of time difference and the known speed of sound.

And because the ultrasonic energy consumption is slow, the distance spread in the medium is far, so it is often used for distance measurement.

The penetration of ultrasonic sensors to liquids and solids is very large, especially in the solid with opaque sunlight, it can penetrate a depth of tens of meters.

The ultrasonic wave will produce significant reflection when it encounters impurities or interfaces to form reflections into echoes, and can produce Doppler effect when it encounters moving objects.

Therefore, ultrasonic probe detection is widely used in industry, national defense, biomedical and other aspects.
