FMCW Radar Level Sensor

Traditional ultrasonic level sensors suffer heavy signal attenuation in dust, vapor and foam environments, while pulsed radar sensors often produce unstable echoes near tank bottoms and low-dielectric media.

Our FMCW Radar Level Sensor applies advanced Frequency Modulated Continuous Wave radar technology, featuring continuous frequency sweep and FFT spectrum analysis. Unlike pulsed radar that relies on single echo signal judgment, FMCW radar outputs stable continuous frequency difference signals, achieving stronger anti-interference, higher resolution and full-tank blind-spot-free measurement.

As a pure non-contact measuring instrument, it requires no contact with liquid, solid or slurry media, eliminating mechanical wear, adhesion and blockage failures. With ultra-narrow beam angle, high-frequency focusing and powerful low-dielectric medium detection capability, it works reliably under drastic temperature changes, heavy dust, floating foam and complex stirring conditions.

Available in three professional models for ordinary liquid, corrosive liquid and bulk solid material measurement separately, it provides targeted industrial level monitoring solutions for different process conditions.

• Advanced FMCW Continuous Frequency Modulation Technology Different from conventional pulse radar, continuous wave frequency sweeping + FFT algorithm ensures more stable signal resolution, effectively filters agitator echoes, tank wall interference and foam clutter.
• True Non-Contact & Maintenance-Free Operation No moving parts and no medium contact. Zero wear, no scaling or adhesion issues, greatly reducing long-term maintenance and replacement costs.
• Powerful Anti-Interference Performance 80GHz high-frequency focused beam avoids false echoes from stirrers, pipes and tank structures. Stable measurement in heavy dust, vapor, condensation and floating foam conditions.
• Millimeter-Level High Precision & Ultra-Small Blind Zone ±2mm high accuracy and ±1mm resolution support full-tank height measurement, realizing reliable detection even near tank top and tank bottom.
• Strong Adaptability for Low-Dielectric Media High-focus narrow beam strengthens signal reflection, enabling stable measurement of low-dielectric liquids, granular solids and powder materials that ordinary radars cannot detect stably.
• Wide Temperature & Pressure Resistance Works steadily under -40℃~120℃ process temperature and -0.1~2.0MPa pressure, adapting most harsh industrial process environments.
• Dual Explosion-Proof Safety Grade Certified Ex ia IIC T6 Ga & Ex db IIC T6 Gb, applicable for Zone 0/1/2 flammable and explosive hazardous areas.
• Multi-Model Targeted Matching Three dedicated models for normal liquid, corrosive liquid and bulk solid materials, realizing professional matching for different working conditions instead of universal ineffective measurement.

This series of 80GHz FMCW radar level sensors features three professionally optimized models for non-corrosive liquid, corrosive chemical liquid, and bulk solid material applications. With ultra-high frequency bandwidth, narrow beam focusing technology and FFT signal analysis algorithm, each model achieves exclusive measuring range, beam angle and structural configuration to adapt to different tank sizes, medium characteristics and industrial harsh conditions.
