80G radar level meter
Production indroduce :
The 76-81GHz Frequency Modulated Continuous Wave (FMCW) radar
products support both four-wire and two-wire applications. With
multiple models, the maximum range can reach 120m, and the blind
spot is as small as 10 cm. Due to its higher operating frequency
and shorter wavelength, it is particularly suitable for solid
applications. By emitting and receiving electromagnetic waves
through a lens, it offers unique advantages in high dust and harsh
temperature environments (up to +200℃). The instrument provides
flange or threaded mounting options, making installation simple and
convenient.
Advantages :
Based on the self-developed CMOS millimeter wave RF chip, a more
compact RF architecture, higher SNR and smaller blind zone are
realized.
The 5GHz working bandwidth enables the product to have higher
measurement resolution and measurement accuracy.
The narrowest antenna beam Angle is 3°, the interference in the
installation environment has less impact on the instrument, and the
installation is more convenient.
The shorter wavelength has better reflection characteristics on the
solid surface, so it does not need to use a special universal
flange for aiming.
Supports mobile phone Bluetooth debugging to facilitate maintenance
work of field personnel.
Technical :
Installation:
There are two points to pay attention to in installation: aim at
the target material level and try to ensure vertical incidence of
the material level; avoid false echo. See the following typical
working conditions.
Ensure that there are no obstructions within the beam range, such
as ladders and steps.

The instrument should be installed at least 20cm away from the
container wall, otherwise it is likely to produce incorrect
readings

The installation of the instrument should ensure that the antenna
beam avoids the feed port, as shown in the figure
Antenna beam avoids feed port
The conical container should ensure that the beam is directly
directed to the bottom of the tank, otherwise the measurement
results at the bottom of the tank may be inaccurate
