In the data sheet section we specify typical values of Tref. 5.1.5 Temperature coefficient α The temperature coefficient of resistance αis defined as the relative change in resistance re-
MANUAL FOR SURFACE TREATMENT OF STAINLESS STEELS

Ferritische stainless steels are more corrosion resistant than the martensitic grades, but less resistant than the austeni - tic grades. Like martensitic grades, these are straight chro - mium steels with no nickel.

It can be shown that the maximum INL aris-ing from this effect is given by IR u LMr/(4 O), 2 which, normalized to the full-scale output voltage, is ap-proximately equal to MR LO/(4r ). For example, if M =1024 and R ...
