The radiometric mold level measurement is maintenance-free and applicable for most mold types. Successful applications can also be found in casters for beam blank and round molds. Although working under extreme temperatures and harsh environmental conditions, the measurement is proven to be reliable for many years of operation.

Measuring Principle

Gamma radiation is attenuated as it passes through the mold. This attenuation is measured by a detector. The extent to which the radiation is attenuated depends on the mold level. The higher the level of molten metal in the mold, the less radiation will reach the detector. In this manner, the mold level can be reliably monitored - irrespective of dust, temperature and vibrations.

GAMMAcast Detectors

GAMMAcast detectors are characterized by their excellent sensitivity for gamma radiation, leading to a significant reduction of source size. The new robust detector design and the PlugProtect cable connection ensure highest mechanical stability and longest lifetime.

Activity Optimized Source (AOS)

The Activity Optimized Source allows for an enhanced measuring performance. By modifying the activity distribution along the source the accuracy around the set point can be significantly improved.
Alternatively, when the accuracy is to remain unchanged, the source activity can be reduced by several factors. This allows for the use of a smaller shield, which is a major benefit in terms of space and costs. In individual cases it is also possible to work with the significantly more cost-efficient lead as shielding material.
