HR730 Series 80GHz Radar Level Meter

The HR730 series 80GHz Radar Level Meter refers to the products which work at a frequency modulated continuous wave (FMCW) of 76-81GHz and support four-wire and two-wire applications. There are multiple models of this series, with a blind zone up to 8cm and a range up to 120m. Based on self-developed CMOS millimeter wave RF chips,the products can achieve a more compact RF architecture, higher signal-to-noise ratio, and smaller blind zones. Fearless of the attenuation of radar echoes by steam and dust; Stable measurements can still be achieved for materials with weak reflection characteristics or low dielectric constants.



HighReach self-developed CMOS millimeter wave RF chips achieve a more compact RF architecture;

The 5GHz working bandwidth enables the product to have higher measurement resolution and accuracy;

The minimum antenna beam angle is 3°, and the interference in the installation environment has a smaller impact on the instrument;

Shorter wavelength, better reflection characteristics on solid surfaces, greatly reducing dependence on universal flanges;

Support remote debugging and upgrading, which can reduce waiting time and improve work efficiency;

Support Bluetooth debugging for mobile phones, making it easy for on-site personnel to maintain.
