LEDAER DKR Series
80GHz FMCW Radar Level Transmitter: Millimeter Precision for Complex Environments
📌 Overview
The DKR Series represents the next generation of industrial level sensing, utilizing 80GHz Frequency Modulated Continuous Wave (FMCW) technology. With a significantly narrower beam angle (down to 3°) and higher signal bandwidth, these radars deliver millimeter-level precision (±1mm) and a massive measuring range of up to 120 meters. It is the ultimate solution for high-dust solids, complex tanks with internal obstructions, and high-purity liquids.
📊 DKR Selection Guide (80GHz Models)
| Model | Application | Key Features | Max Range | Precision |
|---|---|---|---|---|

| D802 | Corrosive / High Temp | Anti-corrosive lens; up to 220°C | 120m | ±1mm |
| D803 | Small Tank / Narrow | Small Lens; 8° beam angle | 120m | ±1mm |
| D804 | Heavy Dust / Solids | Universal Flange with Purge Port | 120m | ±1mm |
| D805 | Aggressive Acids | Small Anti-corrosive Lens | 120m | ±1mm |
| D806 | High Temp & Press | Specialized for 1000°C / 3MPa | 120m | ±1mm |
✨ Why Upgrade to 80GHz?
Ultra-Narrow Beam (3°)
Like a laser, it avoids “ghost echoes” from tank walls, agitators, and heating coils.
Extreme Dust Penetration
Higher frequency allows it to “see through” thick dust clouds in cement and coal silos.
Millimeter Accuracy
Reliable ±1mm precision for inventory management and high-value fluid transfer.
Small Blind Zone
Minimum blind spot of only 8cm maximizes the usable volume of small tanks.
Smart Maintenance
Supports Bluetooth debugging via mobile phone, significantly reducing site maintenance time.
🏭 Application Environments
Cement, coal powder, grain, and fly ash (D804 specialized).
Steel mills and molten material tracking (D806 up to 1000°C).
Strong acids, volatile solvents, and pressurized vessels (D802/D805).
Long-range water level monitoring up to 120m with absolute stability.
