VALUE AND TOLERANCE These thermistors have a narrow tolerance on the B-value, the result of which provides a very small tolerance on the nominal resistance value over a wide temperature range. For this reason the usual graphs of R = f(t) are replaced by Resistance Values at Intermediate Temperatures Tables, together with a formula to calculate the characteristics with a high precision. FORMULAE TO DETERMINE NOMINAL RESISTANCE VALUES The resistance values at intermediate temperatures, or the operating temperature values, can be calculated using the following interpolation laws (extended Steinhart and Hart ): ( R(T) R ref e A + B T + B T + C T ) () T (R) = R A + B ln--------- + C R ln --------- R + D ref R ln --------- R ref R ref () where: A, B, C, D, A, B, C and D are constant values depending on the material concerned; see table below. R ref is the resistance value at a reference temperature (in this event 5 C). T is the temperature in K. Formulae numbered and are interchangeable with an error of.5 C in the range 5 C to 5 C and.5 C in the range - 4 C to + 5 C. DETERMINATION OF THE RESISTANCE/TEMPERATURE DEVIATION FROM NOMINAL VALUE The total resistance deviation is obtained by combining the R 5 -tolerance and the resistance deviation due to B-tolerance. When: X=R 5 -tolerance Y = resistance deviation due to B-tolerance Z = complete resistance deviation, then: Z X + --------- Y = + or Z X+Y --------- % When: = temperature coefficient ΔT = temperature deviation, Z then: ΔT = ------------ The temperature tolerances are plotted in the graphs on the previous page. Example: at C, assume X = 5 %, Y =.89 % and = 5.8 %/K (see Table ), then: 5 Z + ---------,89 = + ---------- % = {,5,89 } % = 5,945% ( 5,9% ) Z 5,9 ΔT = ------------ = ---------- =,67 C (,7 C) 5,8 PARAMETER FOR DETERMINING NOMINAL RESISTANCE VALUES NUMBER B 5/85 (K) NAME TOL.
