Abstract :
The relationship between the characteristics of various thermoelements (TEs) as voltage or current converters and the overall AC-DC differences of a voltage range in a coaxial thermal voltage converter (TVC) set is described. An algorithm to predict the relationships between the AC-DC differences of individual voltage ranges with different TEs is presented, and a method for recharacterizing A TVC containing a replacement TE is given. The measured results show that for most applications a complete recharacterization of the TVC set is unnecessary
