ECcast - Eddy Current Mould Level Measurement

ECcast LB452-EC unitECcast - Berthold's electromagnetic measurement system - measures the mould level reliably and extremely accurately, and is not affected by casting powder or slag. ECcast can be used as a stand-alone system or for even higher process reliability it can be combined with the radiometric GAMMAcast systems.

System characteristics

Best accuracyHigh resolution <0.1 mmQuick response timeNot affected by casting powder or slagNo radioactive source requiredEasy retrofit of existing casters

Measuring Principle

A coil inside the sensor generates an electromagnetic field, penetrating deep into the mould. As a result eddy currents are induced in the top layer of the molten metal. These eddy currents in turn generate a counteracting electromagnetic field – its strength being proportional to the distance between sensor and molten metal inside the mould. In this way the mould level can be determined very precisely and irrespective of casting powder or slag.

Combination: ECcast plus GAMMAcast

The two technologies eddy current and nucleonic complement each other to the top system for highest demands. Benefit from

Large measuring rangePerfect automatic start-upHighest safety due to redundancyPossible determination of casting powder thickness
