Bubela T. Pre-standardization investigations of the qualiti surveillance method of the thermocouple wire.

Present thesis is dedicated to develop the optimal method of the quality surveillance of thermoelectrod materials with its further standartisarion to be able for direct application during fabrication process of the materials. Proposed method enables to apply the contactless measuring supplying vortical currents. Experimental study of influence of the thermoelectrical homogeneity on the thermoelectrical and electrical properties of the thermocouple wire was carried out. Model of the parametric vortical current converter was analized, behaviour and possible influence of the interfering factors on the output signal of the converter were investigated. Complex approach to build up installation for the practical realization of the proposed method of the quality surveillance of thermoelectrod materials aimed to its further standartization was developed.
