Conclusions
The results thus obtained can be used for designing thermistor bridge circuits according to the above-mentioned requirements. Different procedures can be used for computing a specific circuit. However, in every case it is necessary to aim at meeting the requirements of the auxiliary bridge operation under conditions of a small unbalance, and ensuring that the dc power which heats thermistor T should amount to 1/3 of the total power. In view of the dispersion of thermistor parameters it is advisable to make the initial selection of thermistors for the bridge so that when the thermistors are replaced the bridge can be reset solely by means of the adjustable bridge components.
