Radar level device optimized for solids

New Krohne Optiwave 6300C designed for reading uneven surface of bulk storage containers.

The Optiwave has a narrow 2° beam angle.

The Krohne Optiwave 6300 C measures powder, granulates, and bulk solids in buffer silos, hoppers, bulk storage containers, and on conveyor belts. Its design makes it suitable for a variety of industries, such as minerals and mining, food, chemicals, pulp and paper, and power.

The company says its innovative drop form plastic antenna generates a 2° beam angle, which is narrower than conventional configurations. This eliminates the need for an antenna aiming kit to amplify the reflected signal. The shape also prevents crusting or dust layers on the antenna making it ideal for applications with dust formation, such as mineral powders, granulates, or wood chips.

The Optiwave 6300 C comes with a variety of options, and users can choose a 3 in. diameter (DN 80) antenna made of Polypropylene (PP) or Teflon (PTFE), or a 6 in. diameter (DN150) antenna of PP. Conventional stainless steel horn antennas up to 6 in. (DN 150) with built-in horn purging are also available.

Krohne says the unit’s installation wizard is specifically adapted for bulk solid measurement, and features quick set-up and a comprehensive help function. A large screen with a four-button keypad makes navigation easy, and the wizard displays information in nine languages, including Chinese, Japanese and Russian. ATEX, FM, and CSA certifications are pending.
