New level radar offers highest precision in harsh environment – even with strong level fluctuation

FREIBURG, Germany - June 18, 2025 - PRLog -- OndoSense presents its new radar sensor for high-performance level control: The OndoSense apex Level Line enables high-precision and fast level measurements in harsh industrial environments with extreme temperatures, smoke, and dust – e.g. for molten metal level monitoring or for throughput measurements on conveyor belts. The radar level sensor consistently delivers reliable measurement results with an accuracy of up to 0.1 millimeters, even with strongly fluctuating levels. This is due to a unique combination of a high measuring rate (500 Hz) and smart filter algorithms. As a result, the OndoSense apex Level Line ensures error-free, precise measurements at all times, even in the presence of wave motion, bubble formation or other abrupt level fluctuations. The level radar is also suitable for measurements in closed containers requiring a high resistance to heat, temperature, or pressure. For this purpose, OndoSense supplies an air-cooled housing that can be easily attached to the container lid from the outside. This innovative radar solution allows, for example, level monitoring of closed melting furnaces with metal temperatures of up to 1600 degrees Celsius.

Wide range of applications – large selection of interfaces

The OndoSense apex Level Line 's application spectrum ranges from level monitoring of molten metal in slab casting, in ladles, ladle cars, launder systems, melting furnaces and crucibles to throughput measurements on conveyor belts and level or volume measurements of bulk material stockpiles in mining.

The radar level sensor offers a wide selection of interfaces: The OndoSense apex Level Line is equipped with either an advanced Profinet interface or a proven analog current interface (4–20 mA). Three digital switching outputs (PNP/NPN) are also available. The level sensor's measuring range starts at just 0.1 meters and extends to 40 meters. Thanks to preconfigured application profiles in the configuration software, customers benefit from simple and fast sensor commissioning.

Consistently precise measurements – even with abrupt level fluctuations

The OndoSense apex Level Line offers reliable and highly accurate measurements at all times. This even applies to strong level fluctuations, which pose a major challenge for level sensors and can lead to inaccurate measurements.
