April 23, 2025 Beverly, MA (KROHNE release) — KROHNE, Inc. will highlight its advanced level measurement technologies at the Powder & Bulk Solids Conference & Exhibition, scheduled for April 29 to May 1, 2025, at the Donald E. Stephens Convention Center in Rosemont, Illinois. At Booth #2608, attendees can see a comprehensive portfolio of precise, reliable and cost-effective level measurement solutions for challenging powder and bulk solids applications, including the OPTIWAVE 6500, OPTIWAVE 6400, OPTIWAVE 1540 and SHD 200.
The OPTIWAVE 6500 is a 2-wire 80 GHz radar (FMCW) level transmitter for demanding applications with powders in dusty atmospheres. With its small beam angle, it is particularly suited for continuous, non-contact level measurement in high and narrow silos, hoppers or buffer storage containers up to 328 feet. Due to the high signal dynamics of the FMCW radar, the level transmitter is ideal for low-reflective media, dust, uneven surfaces or tanks with obstacles. It features a flush-mounted PEEK lens antenna, so there is no intrusion of the antenna into the tank. The OPTIWAVE 6500 provides accurate and reliable readings in process conditions with temperatures up to 302°F and pressures up to 580 psig.
Also on display will be the OPTIWAVE 6400, a 2-wire 24 GHz radar (FMCW) level transmitter for basic solids applications. Designed for continuous, non-contact level measurement of stones and other products in solids processing, OPTIWAVE 6400 provides accurate and reliable readings, even with uneven product surfaces or dusty atmospheres. Due to its small beam angle and its high dynamic range, the 24 GHz radar can measure distances up to 328 feet. This makes it a cost-effective, yet more powerful alternative to pulse radar transmitters. It also has approvals for use in hazardous areas. The radar transmitter offers flange or thread connections as well as optional antenna extensions to suit any nozzle length.
KROHNE will also showcase the OPTIWAVE 1540, an economical 80 GHz radar (FMCW) level transmitter tailored for liquid chemicals and open channel flow applications. It delivers non-contact level measurement with high accuracy for use in intermediate bulk containers (IBCs), chemical tanks, and wastewater applications. With a measuring range of up to 49 feet and pressure tolerance of up to 72.5 psi, it ensures reliable performance in demanding conditions.
The OPTIFLEX 2200 guided radar (TDR) level transmitter, which measures distance, level, volume and mass in storage and process applications across industries such as chemical, oil & gas, power, food and wastewater, will also be at the booth. Featuring software-based dynamic parasite rejection (DPR) technology, it eliminates false reflections caused by environmental disturbances or product build-up.
Additionally, attendees can learn about the SHD 200 loop-powered device designed for monitoring process parameters in industrial applications. Compatible with all loop-powered field devices operating within the 4–20 mA range and supporting HART communication, the SHD 200 displays up to four customizable measurement pages with advanced features such as trend graphs and summary pages.
