This is a case study of an electromagnetic induction sensor developed for high-temperature heat treatment furnace processes.
Special Steel Manufacturing Company Purpose of Introduction: Control of Copper Strip Waviness CPC control using electromagnetic induction to prevent waviness of the strip in the heat treatment furnace. In the high-temperature heat treatment process, sensors using electromagnetic induction can measure the center position of the strip with an accuracy of ±5mm. It features a maintenance-free structure that can withstand long-term use. *For more details, please refer to the PDF document or feel free to contact us.
