KROHNE expands its OPTIWAVE series of frequency-modulated continuous-wave (FMCW) radar level transmitter offerings with six 24- and 80-GHz transmitters. The transmitters are designed for liquid and solid applications and each device has a particular application target area, including agitated and corrosive liquids, narrow tanks with internal obstructions, or powders and dusty atmospheres.
The devices feature 2-wire, 4 mA to 20 mA HART 7 communication, and come with a choice of process connections starting from ¾-in. They feature a large backlit LCD display with four-button keypad, a quick setup assistant, and PACTware device type manager (DTM) with full functionality.
The devices for liquids include the OPTIWAVE 3500 with an 80 GHz FMCW radar aimed at hygienic applications in the food, beverage and pharmaceutical markets; OPTIWAVE 5400, a 24 GHz FMCW radar for liquids in basic process applications in chemical, oil & gas and power industries; OPTIWAVE 7400, a 24 GHz FMCW radar designed for liquids in harsh environments such as tanks with agitators containing corrosives; and OPTIWAVE 7500, a 80 GHz FMCW radar covering the same industries as OPTIWAVE 7400 but with an 80 GHz radar that can even measure through tank roofs made of non-conductive material.
Devices for solids include the OPTIWAVE 6400, a 24 GHz FMCW radar for solids from granulates to rocks in industries such as minerals and mining, chemical, agriculture, or power generation; and OPTIWAVE 6500, a 80 GHz FMCW radar for powders and dusty atmospheres, equipped with special features that meet the challenges linked to fine powders such as dust, low-reflective media, build-up, and uneven surfaces.
