Explosion Proof Large Lens Antenna Radar Level Transmitter for Industrial Silos

The wireless radar level gauge employs advanced 80GHz Frequency-Modulated Continuous Wave (FMCW) technology, integrated with industrial IoT connectivity (LoRaWAN/NB-IoT/5G), to deliver high-precision, non-contact continuous level measurement even in challenging conditions including dust, vapor, and foam. Its millimeter-wave penetration capability ensures reliable detection through interference layers, achieving measurement resolution as fine as ±1mm. This eliminates inaccuracies commonly associated with conventional instruments under complex process conditions. Featuring IP69K protection and an intrinsically safe design, the gauge offers a maintenance-free and robust monitoring solution for demanding industries such as chemical, energy, and metallurgy.

• Millimeter-Wave Penetration: Utilizes 80GHz high-frequency radar (3.75mm wavelength) to penetrate foam, dust, and vapor, offering a 300% improvement in accuracy compared to conventional 26GHz radar systems.
• Extreme Environment Resilience: Operates reliably across a wide temperature range (-196°C to 200°C), withstands pressures up to 100 bar, and carries Ex ia IIC T6 explosion-proof certification for unmatched adaptability in harsh conditions.
• Maintenance-Free Operation: Non-contact measurement with self-cleaning antenna design ensures 10 years of maintenance-free service. MTBF exceeds 15 years, resulting in near-zero operational costs.
• Smart Ecosystem Integration: Features built-in AI echo analysis for early warnings (e.g., foam/crystallization). Data is seamlessly transmitted to DCS or cloud platforms and supports digital twin modeling for advanced tank management.
• Wireless Flexibility & Long-Range Connectivity: Enables over 8 years of battery life with 4 daily reports. LoRaWAN support extends transmission range to 5 km, ensuring full signal coverage in challenging terrains such as mountainous areas and underground tank farms.

• High-Temperature Molten Metal: Level monitoring in steel ladles and aluminum molten metal tanks (up to 1500°C), equipped with a ceramic antenna resistant to splashes and thermal shock.
• Heavy-Dust Environments: Reliable measurement in cement and pulverized coal silos with dust concentration exceeding 200g/m³, ensuring continuous level control under low visibility.
• Boiling or Foaming Media: Accurate level tracking in petrochemical reactors and asphalt tanks using intelligent echo algorithms to suppress foam interference.
• High-Pressure Steam & Corrosive Liquids: Suitable for boiler drum applications under 10 MPa with steam resistance; PTFE-sealed antenna design for hydrochloric acid and electrolyte tanks.
• Large-Scale Storage Tanks: Covers LNG tanks over 40 meters high; supports multi-sensor network deployment to ensure full coverage without blind zones.
• Food & Pharmaceutical Grade: Hygienic level measurement in milk fermentation and syrup storage tanks using FDA-compliant 316L polished antennas.
• Off-Grid or Remote Applications: Ideal for crude oil pits and remote reservoirs; operates with solar power and redundant battery supply for continuous off-grid functionality.
