RESISTANCE TEMPERATURE CHARACTERISTIC (Rt)

. Rt is defined by IEC standard, pub. 751: alpha = 0.00385 ohm/ohm/°C.
... For range -40°C. to 0°C. RT = Ro[1+At+Bt²+C(t-100°C.) t³]
... For range 0°C. to +150°C: RT = Ro(1+At+Bt²)

Constants in these equations are: A = 3.79782 x 10-³ B = 6.502 x 10-7 C = 4.3735 x 10-¹²

Rt = Ro[1+At+Bt²]
Rt = 100[1+(3.79782 x 10-³ x 100)+(6.502 x 10-7 x 100²) ]
Rt = 100[1+.379782 +.006502]
Rt = 100 x 1.386284
Rt = 138.628 ohms at 100°C.

Rt = Ro[1+At+Bt²+C(t-100) t³]
Rt = 100[1+(-.1519128)+(.00104032)+(.00003918656) ]
Rt = 100 x .8491667
Rt = 100[1+(3.79782 x 10-³ x -40)+(6.502 x 10-7 x -40²)+ (4.3735 x 10-¹²x (-40-100) x -40³) ]
Rt = 84.916 ohms at -40°C.
