New radar level device for solids
While most radar level devices can measure solids or liquids, there are specific characteristics of solids that can make the job more challenging, and this new product has those in mind.
Krohne Inc., has introduced its Optiwave 6300 C radar level device, designed specifically for measuring the uneven surface of solids typical in silo storage. Using FMCW (frequency-modulated continuous wave) technology, the new units are optimized to measure powder, granulates, and bulk solids in buffer silos, hoppers, bulk storage containers, and on conveyor belts. Krohne expects that the design will have many uses in a variety of industries, such as mineral and mining, food, chemicals, pulp and paper, and power.
The company says the innovative drop form of the Optiwave’s plastic antenna generates a 2° beam angle, smaller than most conventional antennas. This makes an antenna aiming kit to amplify the reflected signal unnecessary. The drop form also prevents crusting or dust layers on the antenna, making it ideal for applications with dust formation, such as mineral powder and 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. (DN150) PP model. Conventional stainless steel horn antennas up to 6 in. (DN 150) with built-in horn purging feature are also available.
The installation wizard is specifically adapted for bulk solid measurement. Start-up is easy with help functions. A large screen with a four-button keypad makes navigation easy, and the wizard displays information in nine languages.
