The Ultrasonic Probe for Oxygen Concentration Monitoring Ultrasonic Sensor

The ultrasonic probe for oxygen concentration monitoring ultrasonic sensor
Ultrasonic transducer, ultrasonic transducer, ultrasonic transducer.
Ultrasonic sensor is the use of ultrasonic characteristics of the development of the sensor.
Ultrasonic wave is a kind of mechanical wave that is higher than the frequency of the sound wave, and the ultrasonic wave is produced by the vibration of the piezoelectric ceramic chip under the excitation of the voltage,
It has high frequency and short wavelength, the diffraction phenomenon of small, especially directional good, can become the rays and directional propagation.
The ultrasonic sensor also has the advantages of high sensitivity, small size, light weight, firmness, high precision, good consistency, low power consumption and high accuracy.
Advantages of using in a polluted environment.
Because the ultrasonic directivity is very strong, the ultrasonic sensor to a certain direction to launch ultrasound, on the way to encounter obstacles on the return immediately,
Based on the time difference principle and the sound velocity, the distance from the point of departure to the obstacle is easily calculated.
And because the ultrasonic energy consumption is slow, the distance in the medium is far away, so it is often used to measure the distance.
Ultrasonic sensor for liquid, solid penetrating ability is very big, especially in the sun opaque solid, it can penetrate the depth of tens of meters.
Ultrasonic encounter impurities or the interface can produce significant reflection reflection into the echo formation, encounter moving objects can produce the Doppler effect.
Therefore, ultrasonic probe detection is widely used in industry, national defense, biomedicine and so on.
Suitable range:
1, household appliances and other electronic equipment remote control device;
2, ultrasonic probe ranging, auto reverse collision device and ultrasonic proximity switch;
3, anti theft, disaster prevention equipment, ultrasonic transmission and reception.
