Have you noticed? Electronic boards used to be dominated by Pt100/Pt1000; today it is almost always NTC.And yet “on paper” NTC looks like the worse choice.Pt100/Pt1000 sensors (the PTC family) are accurate and, above all, linear: a direct match between resistance and temperature. A Pt100 reads 100 Ω at 0 °C and rises by 0.385…
