Is there a way to measure the temperature in an induction oven for melting of aluminium(700 C). The pyrometer I’m using can’t correctly display the temperature when the system is running because it interferes with the induction field. The non-contact IR-camera has been abandoned because of the insufficient stirring of the material that gives an oxidation layer on the material and therefore inability to correctly measure the temperature. I’ve started to look on a system with thermocouples covered in a sialon tube to protect them from corrosion. Industry workers say that the wires might be induced even though you use shielded and twisted wires. What’s you opinion on this problem. Any solutions will be happily received.
