Instrument Overview
The YGQRD-76X series of 80 GHz radar level transmitters are Frequency Modulated Continuous Wave (FMCW) products operating in the 76-81 GHz band. They support both two-wire and four-wire applications, are available in multiple models, and have a measuring range of up to 120 m.
YGQRD-76X series 80GHz radar level meters are based on self-developed CMOS millimeter-wave RF chips, achieving a more compact RF architecture, higher signal-to-noise ratio, and smaller blind zones. Resistant to steam and dust attenuation of radar echoes; stable measurement is still possible for materials with weak reflection characteristics or low dielectric constants. With a 5GHz operating bandwidth, the product achieves higher measurement resolution and accuracy.
