80 gigahertz reliability

As one of Europe’s leading steel producers, voestalpine Stahl GmbH manufactures, refines and develops highly innovative steel products for challenging applications in the automotive, electronics, building construction and technology, household appliances and processing industries. To avoid interruptions or downtime at the plants, reliable level measurements are imperative. For years, the company relied on rope probes to monitor the levels for the 45 different materials and granules stored at many of the 160 bunkers located at the headquarters in Linz, Austria. If the bunkers were filled too fast however, the ropes rubbed against the top edge of the bunker, influencing the signal. For this reason, managers at the company were enthusiastic about Endress+Hauser’s latest radar instruments: the Micropilot FMR67 with 80 gigahertz technology. The device features a drip-off antenna and small beam angle that provides superior accuracy in even the harshest conditions. This claim was verified during testing, when voestalpine Stahl GmbH used a conveyer to spread carbon dust equally across three bulk containers. Even at high filling speeds, the signal indicated the correct level.
