LEDAER D804
80GHz FMCW Radar Level Sensor: Optimized for Bulk Solids & Dusty Environments
📌 Brief Introduction
The ledaer Technology D804 is a heavy-duty 80GHz FMCW radar level sensor specifically designed for bulk solids and dusty environments. Equipped with a universal joint flange and an integrated air-purge system, it ensures continuous, maintenance-free measurement in the most challenging silos and bins.
🔍 Product Details
Measuring solids is notoriously difficult due to uneven surfaces and heavy dust. The D804 solves this using 80GHz high-frequency technology, which provides better reflection on solid surfaces. The universal flange allows operators to aim the beam precisely at the material discharge point, while the air-purge connection keeps the antenna clean from dust buildup and material “bridging.”
