OPTIWAVE 6500 C
The OPTIWAVE 6500 C is a high-performance 80 GHz FMCW radar level transmitter purpose-built for fine powders and heavily dusty atmospheres. Measuring bulk powders often involves low-reflective media, extreme dust, and uneven surfaces; the 6500 C overcomes this utilising incredibly high signal dynamics and specific solid-profiling algorithms. Its flush-mounted PEEK Lens antenna ensures zero intrusion into the silo, making it highly robust.
Key Applications of OPTIWAVE 6500 C:
Specifically engineered for Metals, Minerals & Mining, Agri-food, and Chemical sectors. Flawless operation in narrow, highly obstructed silos containing fine powders, ash, or low-dielectric materials.

- Extensive choice of threaded (≥1½”) and flanged (≥DN50 / 2″) process connections
- Compatible with a 112 mm (4.4″) antenna extension
- Supplied with comprehensive PACTware™ DTM configuration software
Frequently Asked Questions
Yes, the OPTIWAVE 6500 C thrives in heavy dust. Its extremely high signal dynamics and specific 80 GHz algorithms filter out airborne particles to read the actual product surface.
No, you generally do not need an aiming kit due to its small beam angle. However, if silo geometry dictates a specific angle, a slanted flange can be directly installed.
The device features a maximum measuring range of 100 meters (328 ft). For tall nozzles, a 112 mm (4.4 in) antenna extension is also available.
It safely operates in process temperatures up to +200°C (+392°F) and handles process pressures up to 40 barg (580 psig).
No, the OPTIWAVE 6500 C utilizes a flush-mounted PEEK Lens antenna. This zero-intrusion design prevents damage from falling bulk material and eliminates dead zones.
