Doing at small project. I’m Verifying the Thermal Coefficient of a metal strip we use to monitor temperature. The metal strip is made from AlCu.
The algorithm we used is
I'm getting different ,alpha value for different temperature ranges.
TEMPERATURE RANGE 22C to 46C , α, of 0.00373/degC
TEMPERATURE RANGE 32C to 46C α, of 0.00365/degC
THIS one confuses me when T0 =32C and the sample is at room temperature:
So, Temperature range is 32C-22C
Using Resistance values above at 32C and 22C I'm getting an average α, of 0.00383/degC.
Can anyone explain this to me?
So why for Temp Range 22-46c I get ~0.00373
for Temp Range 32-46C, I get ~0.00365
and for Temp range 32-22C I get ~0.00383.
Many Thanks
