I'm trying to get an estimation of the temperature that a Kanthal (A1) wire would get, when applied an amount of electrical power.
The wire is 30cm long. The diameter is 0.3mm (or there about). The electrical resistance from the specifications sheet says "1.45 Ω mm2/m" (I'm not sure how to read this). I'll actually leave you the spec sheet link: https://www.kanthal.com/en/products/material-datasheets/wire/resistance-heating-wire-and-resistance-wire/kanthal-a-1
In the specifications sheet they provide a temperature table, from which I kind of understood that the temperature is not going to be a linear function, but a rough linear estimation would be just fine.
My ultimate goal is to calculate the minimum and maximum electrical power that I need to supply to the wire, in order to control it between
50°C and 100°C 100°C and 200°C.
Edit, as requested by @Transistor
I am unsure where to find a more appropriate spec sheet, in that page you can expand the sections to reveal the data. Anyway, I have also found these 2 pages:
Maybe they provide more useful information.
The "element" will be used for a foam wire cutter (thus, not really an element, just a bare wire). As far as I could find, foam can be cut at 200°C, but that may be too aggressive so I'd like to keep it a good amount below that temperature. I am going to make tests later, but right now I only need to "convert" W to T(°C) in order to calibrate an initial electrical circuit...
