The YLR80G series is a high-precision 76–81 GHz FMCW (Frequency Modulated Continuous Wave) radar level meter, also referred to as a millimeter-wave radar. Operating in a higher frequency band than traditional Ku-band radars, it offers superior performance in long-range imaging, multi-spectral sensing, and detection in challenging environments with strong smoke, dust, or steam. Its high resolution allows for precise positioning of smaller targets and ensures reliable measurements even under complex industrial conditions.
With a maximum measuring range of 120 meters and an accuracy of ±1 mm, the YLR80G supports both 4-wire and 2-wire configurations, making it suitable for a wide variety of liquid and solid level measurement applications.
