LEDAER D904
26GHz Parabolic Antenna Radar: High-Gain Solution for Tall Silos & Heavy Dust [cite: 149]
📌 Brief Introduction
The LEDAER D904 is a high-gain 26GHz radar level transmitter engineered for ultra-long-range measurement in bulk solid silos[cite: 148]. Featuring a high-performance parabolic antenna, it excels in capturing signals from up to 80 meters away, even in environments filled with heavy dust, steam, or material crystallization[cite: 149].
🔍 Product Details
The D904 is the go-to solution for the tallest industrial silos[cite: 151]. The parabolic design acts like a satellite dish, focusing the microwave pulses into a tight beam that penetrates dense dust clouds during filling[cite: 152]. This high-gain architecture allows it to detect weak echoes from uneven or sloping solid surfaces that standard horn antennas might miss, ensuring constant data flow for inventory management[cite: 153].

✨ Product Advantages
Ultimate Signal Gain
The parabolic antenna focuses energy more efficiently, providing strong signals even at maximum range[cite: 165].
Extreme Dust Penetration
Specially tuned for cement silos and fly ash bins where dust density is at its peak[cite: 166].
Narrow Beam Focus
Minimizes interference from silo walls and internal bracing in tall, narrow structures[cite: 167].
Self-Cleaning Design
The parabolic shape and high-frequency vibration help reduce material buildup on the antenna.
🏭 Application Scenarios
