Abstract :
The paper deals with a new multi-fiber temperature sensor, based on the relationship between temperature and the refractive index of a suitable reference liquid, substituted to a part of the fiber clad. The sensing element, the microcontroller-based hardware, and the measurement software are described. The results of the rests carried out in the range 40°C-110°C showed good prototype accuracy and repeatability (both contained within ±1°C)
