New radar solution for level measurement of liquid metal

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 steel, aluminium, or copper levels at temperatures up to 1 600 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 300µm, a measurement rate of 300Hz, and a measurement range of 0.1 to 15 metres.

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.

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 moulds. As a general rule, active cooling of the level radar is unnecessary: “A protective window made of ceramic usually offers sufficient heat protection without affecting the high accuracy and quality of the measurements. We have developed an optional heavy-duty housing for special cases to shield the sensor electronics against extreme heat,” says Mathias Klenner.
