Paper Abstract

This article presents the construction and measurement results for a fibre reflectometric temperature sensor. The measurement head in the examined sensor was located at the very end of the measurement path. The operating principle is based on the changes in the light refractive index in the function of temperature. This in turns causes changes in the reflectance in the measurement head. This type of sensors allow to perform measurements in locations which are not easily accessible (small diagonal dimensions of fibre strands with simultaneous long-range transmission of measurement signals) and additionally are not subject to interference from external electromagnetic field, guaranteeing simultaneously high resistance to humidity and vibrations.
