Conditions and Characteristics of the Processes of Heat Transfer in Junctions of Thermoelectric Transducers

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

Models of heat transfer in sensing elements of thermoelectric transducers have been given, which describe the heating of such a transducer in the process of its operation with account taken of the structure of the transducer, the auxiliary reinforcement, and temperature-measurement conditions. Necessary durations of warmup of the sensing elements of thermoelectric transducers, which characterize their thermal inertia, have been determined depending on the rate of their heating and the conditions of contact with the working medium with account of the influence of incomplete thermal contact, the presence of a protection sleeve, the structure of a sensing element, and the property of materials used to fill the sleeve on the integral characteristics of the process of measuring. The presented results may be used for tuning temperature monitoring and control systems and correcting the conditions of installation of thermoelectric transducers, and also for predictive calculations of the measurement error under specified conditions.
