Ultrasonic level switch and radar level switch

The choice of material level measuring instruments, pressure sensors and flow measuring instruments are different.
This is because the material level measurement site conditions vary widely, and it is difficult for producers to design a level measurement radar level switch that meets all application levels.
Only fully understood characteristics and field application conditions can be used to correctly select the desired product, and at the same time, fully utilize the instrument to measure performance. In non-contact liquid level measuring instruments, there are usually two types of ultrasonic level switches and radar material level switches, occupying a dominant position. This is because the application of radar technology has achieved rapid development in recent years.
On the high-frequency radar material level, the switch and the antenna's eyes, the radar level switch echoes the switch on the brain's material level. The radar switch material level measures the electromagnetic wave reflected by the medium, and the quality level of the echo reflection material is applied to the switch. Mass is defined as the ratio of * small echo echo amplitude sum * large noise amplitude.
The quality of the echo displacement sensor of the radar level switch is mainly affected by the following factors:
1. The surface of the measured medium has a smooth surface and its dielectric constant is larger. The radar level switch is more conducive to echo reflection.
2, the dielectric constant of the transmission medium, usually sdfn459ker is more stable and more conducive to communication.
Radar electromagnetic waves, the propagation of electromagnetic waves is not affected by the influence of the medium, only the influence of its dielectric constant.
This is the difference between a major radar technology and ultrasound technology. Therefore, considering the site, special attention should be paid to this aspect: the antenna measures the air distribution between the dielectric constants of the dielectric.
