Microwave solid flow switch model

SFM-200KThe microwave solid flow switch detector is a solid material flow detector designed using the Doppler principle. The Doppler principle refers to the change in wavelength of radiation emitted by an object due to the relative motion between the wave source and the observer. In front of the moving wave source, the wave is compressed, the wavelength becomes shorter, and the frequency becomes higher; When the motion is behind the wave source, it will produce the opposite effect. The wavelength becomes longer and the frequency becomes lower. The higher the speed of the wave source, the greater the effect it produces. Based on the degree of microwave displacement, the velocity of the wave source moving in the observation direction can be calculated. In short, if the position of the object touched by the microwave is fixed, then the frequency of the reflected wave and the frequency of the emitted wave should be equal. If an object moves in the direction of emission, the reflected wave will be compressed, which means the frequency of the reflected wave will increase; On the contrary, the frequency of the reflected wave will decrease accordingly.
