Krohne OPTIWAVE 24 and 80 GHz FMCW radar level transmitters

Krohne has added six 24 and 80 GHz transmitters to the OPTIWAVE series of FMCW radar level transmitters, designed for liquid and solid applications in a wide range of industries. Each device has a particular target area of application. All devices feature 2-wire, 4–20 mA HART 7 communication and come with a wide choice of process connections.

OPTIWAVE 3500 is an 80 GHz FMCW radar aimed at hygienic liquid applications in the food, beverage and pharmaceutical markets, and has a narrow beam angle and small dead zone. OPTIWAVE 5400 is a 24 GHz FMCW radar for liquids in basic process applications in the chemical, oil and gas and power industries, while the OPTIWAVE 7400 is a 24 GHz FMCW radar designed for liquids in harsh environments, such as tanks with agitators containing corrosives, or in non-Ex applications up to 700°C. The OPTIWAVE 7500 is an 80 GHz FMCW radar covering the same industries as OPTIWAVE 7400 up to 150°C, 40 barg.

For solids applications, the OPTIWAVE 6400 is a 24 GHz FMCW radar for solids from granulates to rocks in industries such as minerals and mining, chemical, agriculture or power generation. The DROP antenna minimises scaling and is unaffected by the angle of repose, thus eliminating the need for antenna-aiming kits or purging systems.

OPTIWAVE 6500 is an 80 GHz FMCW radar for powders and dusty atmospheres, suitable for the same industries as OPTIWAVE 6400.
