14. A thermistors resistance varies with temperature as:
R=R0eBT where R is in ohms Ω, T is in kelvins, and R0 and B are
constants. If R=8991.9 Ω at the ice point and R=358 Ω at the steam
point, Ts=373.15K.
Determine B.

2.3 Analytic form of transfer function. In certain cases the transfer function is available as an analytic expression. One common transfer function used for resistance temperature sensors (to be discussed in Chapter 3) is the Callendar- Van Duzen equation. It gives the resistance of the sensor at a temperature T as R(T)= Ro(1+AT+ BT2 - 100CT3 +CT*) [2), where the constants A, B, and C are determined by direct measurement of resis tance for the specific material used in the...
