New radar level sensor solution for liquid metal with unprecedented accuracy and reliability

FREIBURG, Germany - May 17, 2024 - PRLog -- OndoSense is expanding its portfolio in the metal industry: The German radar specialist has developed a sensor solution for the level measurement of molten metal with unprecedented precision and stability. The robust and low-maintenance radar system reliably measures the level of steel, aluminium or copper at temperatures up to 1600 degrees, even in the presence of dust, fumes, smoke, vibrations or sparks. The sensor usually does not need to be actively cooled, which makes commissioning significantly easier. The solution is based on the OndoSense apex radar sensor and features a measurement accuracy of up to 300 µm, a measurement rate of 300 Hz and a measurement range of 0.1 to 15 meters. As a result, OndoSense offers the most accurate and fastest radar sensor for the level measurement of liquid metal. The OndoSense radar solution not only contributes to increasing productivity and reducing costs, but also makes it possible to automate safety-relevant processes that can pose a risk to operators. In addition, it contributes to lowering CO₂ emissions in the metal processing industry.

Minimal maintenance, easy commissioning

Enhanced performance and increased productivity are not the only advantages of the radar system. For instance, the minimal maintenance effort required for radar technology ensures maximum availability: "Radar has no moving parts or sensitive optics. As a result, the longevity of the sensors is very high. In addition, the radar sensor measures faultlessly even when the lens is dirty and only needs to be cleaned very rarely. Temperature fluctuations, metal splashes or reflections have no influence on the level measurement. Our radar sensor technology is easy to integrate and to place into operation. This guarantees an uncomplicated, reliable and highly productive level measurement," says Mathias Klenner, OndoSense Co-CEO and founder.

Active cooling is usually not required

The sensor solution for molten metal level measurement based on the OndoSense apex radar sensor is suitable for crucibles, ladles and troughs as well as for furnaces or casting molds. As a general rule, active cooling of the level radar is not necessary: "A protective window made of ceramic usually offers sufficient heat protection without affecting the high accuracy and quality of the measurements. For special cases, we have developed an optional heavy-duty housing to shield the sensor electronics against extreme heat," says Mathias Klenner. With the OndoSense apex radar sensor, OndoSense sets new standards in sensor and measurement technology for the metal industry.
