📡 AD TECHNOLOGIES – 80GHz FMCW Radar Level Meter
High-Precision Millimeter-Wave Level Measurement Solution
🌐 Product Overview:
The 80GHz Radar Level Meter from AD TECHNOLOGIES adopts FMCW (Frequency Modulated Continuous Wave) technology to deliver millimeter-level accuracy for level measurement of liquids, solids, and corrosive media across various industrial sectors. With advanced signal processing and compact design, it ensures reliability even in challenging environments like dust, condensation, agitation, or extreme temperatures.
🧠 Key Features:
- Proprietary millimeter-wave RF chip for compact architecture
- Exceptionally high signal-to-noise ratio, resistant to level fluctuations
- ±1 mm accuracy, suitable for metrology-level measurements
- Minimal blind zone – ideal for small storage tanks
- Narrow 3° beam angle for focused energy and reduced false echoes
- Effective for low dielectric media (ε > 1.5)
- PTFE lens antenna for excellent anti-corrosion and anti-clogging performance
- Measurement range up to 120 meters
