KROHNE now offers six 24- and 80-GHz transmitters for its OPTIWAVE series frequency-modulated continuous-wave (FMCW) radar level transmitters. The transmitters are designed for liquid and solid applications with each device having a target application including agitated and corrosive liquids, narrow tanks with internal obstructions, or powders and dusty atmospheres.
OPTIWAVE devices feature two-wire, 4-mA to 20-mA HART 7 communication and offer process-connection options starting from 0.75-inch. They feature a large backlit LCD with a four-button keypad, quick-setup assistant, and PACTware device type manager (DTM) software with full functionality. Hazardous area approvals are available, while others, including safety integrity level (SIL), are in process.
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, an 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.
