The resistance Re k of a thermistor at 0 K is given by: Re 1.68 exp[3050X (1/0-1/298)] The thermistor is incorporated into the deflection bridge circuit shown in Fig. 5. (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 ΚΩ. 2.56 V supply Re www R4 1.22 ΚΩ VOUT Figure 5 R₂ R3 1.00 ΚΩ 0.29 ΚΩ The resistance Re k of a thermistor at 0 K is given by: Re 1.68 exp[3050X (1/0-1/298)] The thermistor is incorporated into the deflection bridge circuit shown in Fig. 5.
