Evaluation of Pt100 sensor deflection effect during strain measurements

Abstract

The present work concerns description of additional error sources of temperature measurement done with Pt100 sensors placed on the deflected elements. The authors came across certain problems with temperature measurement while working on an original signal conditioner. For this reason it was decided to conduct more measurement experiments. The aim of experiments was to examine the influence of deflection of Pt100 sensors on their resistance changes. In the article a laboratory stand and the procedure of conducting the research are presented.
