Segmented thermodynamic sensor in temperature shift balance circuit as the power AC/DC transmitter and direct working sub-systems thermo interactivity in thermodynamic systems is described. This paper deals with new thick film sensor used for thermodynamic direct power AC/DC transmission and metering in active industrial systems. In previous papers the basic principle of thermodynamic sensor was introduced and its construction on alumina ceramic substrate with commercial thick film pastes was demonstrated. Generally this sensor has plenty of application possibilities in various areas of industry. Some final users especially from RF area are asking for galvanic isolated sensors independent to contiguous environment effects. Such applications can be realized by the bisected thermodynamic sensor probe. The basic principle of this solution is segmented thermodynamic sensor with the thermodynamic environment temperature shift between more active sensor sections to influence of ambient temperature compensation. The simulation model of segmented thermodynamic sensor as particular segment elements of thermodynamic system was simulated. Values obtained from simulation are compared and discussed with experimental results. There is a good conformity between calculated and measured values. Results obtained from simulations enables construction of new family of segmented thermodynamic sensor probes in balance circuitry models. These could be integrated into many industrial thermodynamic metering systems designed in standardized design environments. They can be used as technical solution in galvanic isolated power measuring systems in integral industrial designs of any complex thermodynamics systems. Namely power and heat distribution, overpower protection systems, thermal circuit breaking systems, HIRF detection systems, etc.
