OPTIWAVE 7500 C (80 GHz)
for liquids in narrow tanks with internal obstructions
This 24 GHz FMCW radar level transmitter is 
designed for liquids in harsh environment like tanks 
with agitators containing corrosives or in non-Ex 
applications with extremely high process 
temperatures, like molten salt in solar plants 
(+700°C / +1292°F). For toxic and dangerous 
products, the use of a Metaglas® second sealing 
barrier is recommended.
The PTFE and PEEK Drop antennas have optional 
flange plate protection for corrosive media. Heating 
and cooling systems prevent from crystallization 
inside the Metallic Horn antennas. The device 
measures distances up to 100 m / 328 ft and can be 
installed in high nozzles (≤1 m / 3.28 ft) when fitted 
with antenna extensions. Standard process 
conditions up to +200°C / 392°F; 100 barg / 1450 psig 
(higher on request).
The small beam angle and negligible dead zone of 
this 80 GHz FMCW radar level transmitter makes it 
the premium choice for liquids in small and narrow 
tanks with internal obstructions like agitators or 
heating coils, as well as tanks with long nozzles. It 
can even measure through tank roofs made of 
non-conductive material (e.g. plastic, fiberglass or 
glass). The flush-mounted PEEK Lens antenna (no 
tank intrusion) is insensitive to deposit.
There is an extensive choice of process connections 
starting from ¾¨. Flanges have an optional PEEK 
plate protection for corrosive tank contents. The 
OPTIWAVE 7500 operates in process conditions with 
temperatures up to +150°C / +302°F and pressures 
up to 40 barg / 580 psig. It measures distances up to 
100 m / 328 ft and a 112 mm / 4.4¨ extension is 
available for high nozzles.
