Overview

The difference between radio frequency admittance technology and traditional capacitance technology lies in the diversity of measurement parameters, the driving three terminal shielding technology, and the addition of two important circuits, which are improved based on valuable experience in practice. The above technology not only solves the problems of cable shielding and temperature drift, but also solves the problem of hanging materials at the root of vertically installed sensors. The two added circuits are a high-precision oscillator driver and an AC phase detector sampler.

SIEMENS radar level gaugeThe wavelength of the 26GHz radar is 11mm, and the wavelength of the 6GHz radar is 50mm. When the radar measures the level of bulk materials, the radar wave reflection mainly comes from the diffuse reflection of the material surface. The intensity of the diffuse reflection is proportional to the size of the material and inversely proportional to the wavelength. That is to say, for the same material, the shorter the wavelength, the easier it is to be reflected, and thus the better the echo signal during radar measurement. For example, when a basketball touches a table tennis ball, the basketball generally does not bounce back, while when a table tennis ball touches a basketball, the table tennis ball is bounced back. However, most bulk materials have a diameter much smaller than 50mm, which is why the current 26GHz radar is the choice for bulk material level measurement.

Due to the harsh on-site environment, dirt, water vapor, etc. will accumulate on the radar antenna over time. The 26GHz radar antenna is small, and adding an antenna cover can greatly improve the impact of dirt and water vapor. The 6GHz radar antenna is large, and adding an antenna cover is difficult. The overall instrument is large, and cleaning is difficult.

SIEMENS radar level gaugeDue to its good directionality, small emission angle, and strong resistance, the high-frequency radar level gauge is very suitable for measuring material levels in silos with large aspect ratios, especially in situations such as calcium carbide furnace and converter silos, where low-frequency radar cannot be used for measurement.

Compared with high-frequency radar, low-frequency radar has a much lower ability to combat dust due to its low frequency, dispersed energy, and insufficient energy concentration.

These reasons determine that high-frequency radar is the mainstream product for solid level measurement, and the difference between low-frequency radar level meters highlights the advantages of high-frequency radar level meters.
