Example of Temperature Gradient Change by External Temperature Sensor (Ther-
mistor)
ture gradients, –0.20%/˚C, –0.40%/˚C and –0.60%/˚C, can be selected as the V
gradients are necessary, a thermistor is connected in series to the resistor R
in Figure 8.8, and temperature gradients can be changed to any values.
gradients than those to be changed are selected from Table 4.1 and are set.)

V
When a thermistor is used for RT, it can make the temperature gradient of V
The thermistor temperature characteristics are non-linear but can be corrected to linear ones when the
resistor RP is connected to the thermistor in parallel.
