The resistance R, kQ of a thermistor at 0 K is given by:
1
Ro = 1.68 exp 3050
298
The thermistor is incorporated into the deflection bridge circuit shown in Fig. Prob. 3.
(a)
Assuming that VOUT is measured with a detector of infinite impedance, calculate:
(i)
the range of VOUT Corresponding to an input temperature range of 0 to 50 °C;
(ii)
the non-linearity at 12 °C as a percentage of full-scale deflection.
(b)
Calculate the effect on the range of VoUT of reducing the detector impedance to 1 k2.
