It would be very advantageous if the condition of molding materials (sand-binder systems) in regenerator units used in foundries could be monitored in real-time. This work presents the results of investigations in this direction. In  it is shown that the condition monitoring can possibly be based on impedance spectroscopy because the resulting curves are characteristic of the material used. This has now been confirmed by measurements on a regenerator typical of the actual application.
