High Precision Liquid Radar Level Meter 80GHz NYRD900 4 - 20mA
80GHz NYRD900 Radar Level Meter Working Principle
Millimeter wave electromagnetic wave : The electromagnetic wave in the frequency domain of 30-300 GHz (wavelength 1-10mm) is usually called millimeter wave, it is located in the overlapping wavelength range of microwave and far infrared wave, so it has the characteristics of two kinds of spectrum. The 76-81 GHz band is the least understood and applied region up to now.
NYRD900 FMCW radar product (also known as centimeter-wave radar), due to the millimeter wave band with higher frequency than ku band radar is adopted, in remote target detection, strong smoke and dust environment, it has important application in remote imaging and multispectral imaging. And it can detect smaller targets and achieve more accurate positioning than microwave radar, with higher resolution and stronger security.
80GHz NYRD900 Radar Level Meter Design Feature
1.Good transient performance:Based on self-developed COMS millimeter wave RF chip. It is independent research and development, and has independent software, independent chip.
2.Small beam angle, small antenna size and easy installation: the smaller the beam angle, the smaller the influence on the measured project, which greatly improves the measurement reliability and accuracy.
3.Low energy: Not easy to destroy the substance to be tested.
4.Large measuring range and small blind area:The good results can also be obtained for small can measurement.
5.Strong penetrability: It can be used to detect the internal structure of material.
