76-81GHz FMCW Level Radar

 Features

The series is 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 wavelength make it ideal for solid applications, includ ing those with extreme dust and high temperature to +200C.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 GHzover 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 Prog ramming

Supports 485 bus protocol (4-wire), seral-port (2-wire) protocol, and hart (2-wire) protocol. It isvery easy to install and configure via an optional graphical local display interface on PC.Or you canmodify the built-in parameters either locally via the push buttons. Or you can use cell phone tocontrol via Bluetooth.

Technical specifications

Install

The main concern of installation is to aim to the material surface under test and on the other hand toavoid false echoes. 

Typical scenes are list below for correct installation. Keep the antenna beam fee ofany interference such as ladders, pipes, steps, as shown in Fig1.

Avoid the contact between antenna beam and feeding flow, as shown in Fig.2.

At least 200mm away from the wall for avoiding false echo.

Aiming the antenma beam to the bottom of tapered vessel for avo iding false echo when the level is at the bottom of the tapered vessel.
