Launder system level control | Molten aluminum & steel | radar-based

The precise level measurement of molten metal in the launder system guarantees a controlled, reliable filling of casting pits, casting ladles and casting molds. Our radar sensors measure the level of liquid steel, copper or aluminum in open or closed launder systems, channels or troughs with a measurement accuracy in the sub-millimeter range – even at a metal temperature of up to 1600 degrees Celsius. This enables a safe, raw material-saving and high-quality casting process of slabs, ingots or billets. The compact OndoSense radar sensors measure reliably even with a dirty lens and usually do not need to be actively cooled. If required, protective housings with optional air cooling are available. Dust, steam, smoke, vibrations or heat radiation do not affect the high precision and robustness of level measurement for gutter systems.

Take advantage of our radar technology for the level measurement of molten metal in launder systems, in DC or die casting, in ladles, ladle transfer cars and casting molds as well as in melting furnaces and crucibles.

Productive.
Optimal control of the launder level.
- Safe and fast filling of casting pits, ladles and molds thanks to the precise launder system level control.
- Productivity gain through resource-saving, high-qualitaty casting of semi-finished aluminum or steel.
Profitable.
Maintenance-free, profitable radar sensor.
- Long service life, minimum maintenance: Radar has no moving parts and works contactless.
- Our radar measures aluminum or steel melts even with a dirty lens or behind a ceramic shielding.
Reliable.
Reliable launder system level control.
- Our radar reliably measures the launder level even in dust, steam, ash or heat.
- With its high measuring rate, the radar sensor enables a dependable, fast filling process.
