Stainless Steel TCR for DNA200

[Jeremy Schreiber]

Hi everyone,

Apologies if this belongs in the DNA200 thread, however, with the influx of amazing DNA200 mods being released right now, I figured that I would more likely get a response posting a new thread.

I just received my uwell Crown tank (wonderful build quality and ease of use, great customer service by Vape Royalty in sending me the Crown after I received a Freemax Starre Pro that was leaking).

The Crown comes with two stainless steel coils and a nickel coil, so I loaded up a TCR from Steam Engine for 316 stainless steel (says SS 316 L /Elite (TFR) ) and plugged in 0.25 ohms which is the resting/base resistance of the coil.

I am using it now and while the temperature control absolutely works, the actual coil temperature is definitely below what it is reading at. I have it at 600F and it feels like it is about at 400 - 430 (maybe less beyond the initial half second of the drag).

Can anyone assist me in modifying the curve that is entered into Escribe to allow the temperature reading to be more accurate?

Thank you,

Jeremy

Check out the later pages of my Beyond Ni200 thread, there's some spreadsheets posted with the TCR curve for Stainless Steel (and various other wires): TC beyond Ni200: Nickel Purity, Dicodes; Ti, SS, Resistherm NiFe30; Coefficient of Resistance | E-Cigarette Forum

For a single TCR value, 0.001 - 0.00105 is the region, but the exact value depends on the variant of SS (304, 316, 317 etc). @vapealone posted some good graphs/numbers in the above thread
