The KJT Series radar level transmitter uses 76–81 GHz FMCW millimeter-wave technology to deliver high-precision, non-contact level measurement for liquids and solids. Compared with traditional radar and guided wave systems, it offers higher accuracy, narrower beam angles, and stronger resistance to dust, smoke, and harsh environments.
Its strong penetration and ultra-narrow beam ensure stable and reliable performance in complex industrial conditions. The transmitter is ideal for applications in water and wastewater treatment, mining, mineral processing, metallurgy, and utility engineering.
