64-80GHz FMCW Level Radar is a radar sensor for continuous level measurement of liquids. Sino-Inst also launched a radar level sensor operating at 76-81 GHz.
Sino-Inst offers a variety of Radar Level Sensors for industrial level measurement. If you have any questions, please contact our sales engineers.
Features of 76-81GHz FMCW Level Radar
The LM78xx series is an FMCW radar operating at 76-81 GHz, which has a maximum measuring range of 120m and a minimum blind zone of 8cm. It supports 4-wire and 2-wire applications. Higher operating frequency and shorter wavelengths make it ideal for solid applications, including those with extreme dust and high temperature to + 200℃.
The radar consists of an electronic circuit coupled to a lens antenna and flange for quick and easy positioning.
The main benefits of using 78 GHz over devices using lower frequency are:
- Based on the self-developed CMOS millimeter wave RF chip, a more compact RF architecture, a higher signal-to-noise ratio, and a smaller blind zone are realized.
- 5GHz working bandwidth means higher measurement resolution and accuracy.
- 3°antenna beam angle, so the interference in the environment has less impact on the instrument, and the installation is more convenient.
- Shorter wavelength yields good reflection properties on sloped solids, so aiming towards material angle of repose is usually not necessary.
- Support remote debugging and remote upgrading to reduce the cost of field personnel.
Communication and Programming
LM78XX supports 485 bus protocol (4-wire), serial-port (2-wire) protocol, and hart (2-wire) protocol. It is very easy to install and configure via an optional graphical local display interface on a PC. Or you can modify the built-in parameters either locally via the pushbuttons. Or you can use a cell phone to control LM78xx via Bluetooth.
