I'm new here, and I hope I'm posting this in the right place. My colleagues and I are trying to take the temperature of a steel wire as it's heated. We're heating it by putting a current through it. The problem we're encountering is that the thermocouple we're using to take the temperature of the wire only has surface contact at the tip, and we need a more comprehensive idea of the temperature along the wire. The end goal is to determine the coefficient of thermal expansion. Any thoughts?
