PRINCIPLE: 76-81GHz FM continuous wave (FMCW) radar

Products Categories

The DRUL-99G level meter is a frequency modulated continuous wave (FMCW) radar product operating at 76-81 GHZ. Because of its higher operating frequency and shorter wavelength, it is especially suitable for solid applications. The working mode of transmitting and receiving electromagnetic waves through the lens has unique advantages in the environment of high dust and harsh temperature. This series has several models, the maximum range of products can reach 120m. The minimum blind area should be 8cm. The instrument provides flange or thread fixing method, making the installation convenient and simple.

Product features:

  • CMOS millimeter wave RF chip, more compact RF architecture, higher signal-to-noise ratio, smaller blind area.
  • 5GHz working bandwidth, with higher measurement resolution and accuracy.
  • 3° or 8° antenna beam Angle, installation environment interference on the instrument less impact, more convenient installation.
  • Shorter wavelength, better reflection characteristics on solid surfaces.
  • Support remote debugging and remote upgrade, reduce waiting time, improve work efficiency.
  • Support mobile phone Bluetooth debugging, convenient field personnel maintenance work.
