KROHNE Adds Six New Transmitters for OPTIWAVE FMCW Radar Level Transmitters
KROHNE Inc. has announced six new 24 and 80 GHz transmitters for its OPTIWAVE series of frequency-modulated continuous-wave (FMCW) radar level transmitters. The transmitters are designed for liquid and solid applications in a wide range of industries.
Each device has an application target area, including agitated and corrosive liquids, narrow tanks with internal obstructions, or powders and dusty atmospheres.
All new OPTIWAVE devices feature 2-wire 4…20mA HART 7 communication and come with an extensive choice of process connections, starting from ¾-inch. They feature a large backlit LCD display with 4-button keypad, a quick setup assistant for easy commissioning, and free PACTware™ device type manager with full functionality. Hazardous area approvals are available, while others, including safety integrity level, are in process.
New 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 and 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.
New 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.
The new line of 24 GHz and 80 GHz transmitters complement the two existing 6 and 10 GHz devices used with the OPTIWAVE series. OPTIWAVE 1010 is a 6 GHz FMCW radar suited for clean liquids in bypass chambers and magnetic level indicators (MLIs). It is welded to the bypass chamber or MLI and measures the position of the float or the liquid level. OPTIWAVE 5200 is a 10 GHz FMCW radar for liquids in storage and simple process applications with a wide range of options, SIL2 approval and a choice of fieldbus communication options.
