OPTIWAVE 6500 C (80 GHz)
for powders and dusty atmosphere
Accurate continuous level measurement of fine 
powders has to deal with a series of issues like dust, 
low-reflective media, build-up and uneven surfaces. 
The specific algorithms and high signal dynamics of 
this 80 GHz FMCW radar transmitter are the key to 
provide reliable and accurate readings despite these 
difficult conditions. Thanks to the small beam angle 
of the flush-mounted Lens antenna, this powerful 
device handles high and narrow silos even in the 
presence of internal obstructions.
The OPTIWAVE 6500 operates in process conditions 
with temperatures up to +200°C / +392°F and 
pressures up to 40 barg / 580 psig. It offers an 
extensive choice of threaded (≥1½¨) and flanged 
(≥DN50 / 2¨) process connections. The antenna 
options permit the device to measure distances up to 
100 m / 328 ft. A 112 mm / 4.4¨ extension is available 
for high nozzles.
