Abstract


 

The article proposes a new measuring circuit for temperature control at multiple points of the product using a sequence of thermistors and diodes with three connecting wires and two voltage sources. A mathematical model and a computational algorithm for calculating the resistance of thermistors are presented which consist in the formation and sequential solution of systems of linear algebraic equations for different ratios of voltages of two power sources. A model problem and the results of a computational experiment are considered.
