Principle:
The general principle of a frequency modulated continuous wave 80G high-frequency radar level meter is that the radar emits electromagnetic waves at the top of the tank, which are reflected by the medium and received by the radar. The frequency difference δ f between the received signal and the transmitted signal is proportional to the distance R from the surface of the medium: R=C (velocity) * δ f (frequency difference)/2/K (frequency modulation slope). Since the speed of light C and the frequency modulation slope K are known, the frequency difference δ f can be estimated to obtain the distance R between the radar installation position and the material surface. Then, by subtracting the spatial distance from the radar to the material surface (referred to as the air height) from the known total height of the tank, the height of the material surface can be obtained.
Features:
1. Millimeter wave radar has a measurement accuracy of up to ± 2mm and a lower limit blind zone of 0.1m.
2. The smaller antenna size meets the measurement needs of more working conditions.
3. Multiple lens antennas, smaller emission angles, more concentrated energy, stronger echo signals, under the same mining conditions, compared to
Other radar products have higher reliability.
4. It has stronger penetrability and can be used normally even in the presence of adhesion and condensation.
5. The dynamic signal range is larger, making it more stable for measuring low dielectric constant media.
6. Multiple measurement modes, with a radar response time of less than 1 second in fast measurement mode.
