NTC parameter calculator

The B25/100 constant of an NTC can be determined by measuring the resistance at two different temperatures T1 and T2. Knowing the corresponding resistances R1 and R2 the constant can be calculated as follows:

B_25_100 = (ln(R_1)-ln(R_2))/((1/T_1)-(1/T_2)) [K]

T1 = K   R1 = Ω
T2 = K   R2 = Ω
B25/100 = K
