80GHz Radar Level Transmitter with Universal Purge Flange
for Dusty Solid Materials
JC-50LU Series
80GHz Radar Level Transmitter
Utilizing Frequency Modulated Continuous Wave (FMCW) technology, the transmitter emits a continuous sweep of high-frequency microwave signals. Upon striking the material surface, these signals reflect back to the sensor, which calculates the exact distance based on the frequency shift. What sets this unit apart is its proprietary waveguide measurement architecture.
Operating at 80GHz, the incredibly short wavelength produces a highly focused, narrow beam. This concentrated energy penetrates dense dust clouds and reflects strongly off uneven, inclined solid surfaces, drastically reducing measurement blind zones. Furthermore, the onboard intelligent signal processing algorithms excel at filtering out false echoes generated by internal silo structures or the thick dust clouds present during active filling and discharging cycles, ensuring the true material level is always captured.
| Key Advantages | Details |
|---|---|
| Unique Waveguide Design | Combines a specialized waveguide, horn antenna, and focusing lens to achieve an ultra-narrow beam angle of <2.5° (typical radars: 3–6°). This concentrated energy ensures powerful echo returns from angled solid surfaces and minimizes signal scattering. Effortlessly bypasses internal obstacles like agitators, support beams, and uneven vessel walls, minimizing false reflections. |
| Self-Developed Radar Chip | Powered by a proprietary, highly integrated chip design encompassing PLL, transmitter, receiver, baseband, and ADC. This compact architecture optimizes power consumption and enhances long-term component durability. Chip options: • CMOS silicon-based chip: Delivers a 1.5dB stronger transmission output than standard alternatives, ensuring unwavering stability across challenging solid profiles. • GaAs chip: Up to 18dB power output, engineered for extreme conditions such as high temperature and high pressure, matching the performance of top international brands. |
| High Accuracy & Smart Filtering | Achieves a remarkable measuring accuracy of ±2mm. Extensive measuring range: (0.1 ~ 120) m, covering both small hoppers and massive storage silos. Enhanced by intelligent FMCW algorithms, the system actively filters out severe dust interference and false echoes during dynamic silo filling, maintaining a high signal-to-noise ratio. |
| Wide Applicability | Engineered for the harshest industrial realities, mastering everything from abrasive solid particles and fine powders to corrosive chemical slurries. Performs with absolute reliability across diverse vessel geometries, shrugging off extreme humidity, aggressive airborne particulates, and intense process pressures. |
| Flexible Installation | Standard process connection: G2 thread, optional G1.5, G1 (first G1 thread connection for 80GHz radar in China). The integrated universal purge flange allows for precise directional aiming, crucial for targeting the lowest point of a sloping material bed (angle of repose) while avoiding the incoming product stream. Multiple flange options available (DN50, DN80, DN100, etc.). |
| Non-Contact Measurement & Low Maintenance | The continuous or periodic air purge mechanism actively blasts away dust and sticky residue from the antenna lens. This self-cleaning, non-contact approach eliminates mechanical wear, prevents material bridging, and slashes long-term maintenance overhead. |
