Small blind zone small range liquid nitrogen level measure FMCW
Radar level sensor from 10cm up to 150meter Introduction76 - 81 GHz Frequency Modulated Continuous Wave (FMCW) radar
products, also known as millimeter - wave radars, operate in the
millimeter - wave band, which has a higher frequency than the Ku -
band radar. These radars have significant applications in remote
target detection, in environments with heavy smoke and dust, in
remote imaging, and multi - spectral imaging. Compared to microwave
radars, they can detect smaller targets, achieve more precise
positioning, offer higher resolution, and provide greater privacy. Application field - The emission angle is less than 3 °, which is suitable for narrow
space or guided wave pipeline measurement
- Measuring range could reach to 120M, which is suitable for the
measurement of large storage tanks
- Measurement dead zone is in the range of 7-8CM, suitable for the
measurement of small storage tanks
The product has extremely high measurement accuracy, suitable for
high-precision measurement level measurement - The product has rich echo processing algorithms and empirical data
of various working conditions; it has unique advantages than other
similar products in the application of extremely harsh working
conditions such as strong dust, steam, or special process storage
tanks with stirring and heating rods.
