Rtd Resistance Tables: Pt100
-100 to -10
RTD (Resistance Temperature Detector) resistance vs. temperature reference tables for Pt100, Pt1000, Pt500 (IEC 60751 Callendar-Van Dusen / ITS-90), Ni120 (DIN 43760), and Cu10 (SAMA RC21-4) sensor types. Pt100 covers -200 to +850 C at 10 C intervals with Class AA/A/B tolerance values.
