Radiometric Level Measurement CONGAUGE LB 6755

CONGAUGE LB 6755 is a modern, high-tech radiometric detector, utilizing first-class sensoring technology to continuously measure both the liquid steel level and the thickness of the casting powder layer in a mold during continuous casting.

The radiometric level measurement detector CONGAUGE LB 6755 has been designed in cooperation with SMS Concast and enables  also for controlling of automatic feeders for casting powder, reducing human intervention  in a dangerous area.

CONGAUGE LB 6755 – Your advantages at a glance:

• Measures the steel level and the powder level simultaneously
• Mechanically compatible with LB 6652/6752 installations
• Compatible with LB 452 castXpert
• State-of-the-art SiPM technology
• Automatic calibration rig for steel and powder level supplied
• Superior safety with automatic detection and compensation if a scintillation failure should occur
