Paper Abstract
This paper presents the method of bending force and temperature measurement. For this purpose, a station with a thermal chamber has been designed and a bracket used in further measurements on which Bragg gratings have been mounted. The performance of simultaneous measurements of force and temperature was possible through the use of an appropriate layout of the sensor. The method of indirect measurements was used, using information deriving from the spectrum of the uniform Bragg gratings, placed on the cantilevers. The measuring system scheme was proposed for measuring sizes measured in the form of bending force, acting in two directions, perpendicular to the grating axis. The increase in the sensitivity of the change on the force is obtained in relation to the system, in which only information on the width of the spectrum of one of the gratings would be used. A change in the spectral width value was observed along with the increase in bending forces from 0 to 10N for two cantilever beams schemes. The head of the sensor can reach larger physical sizes, in exchange enabling a measurement of force and temperature in many places, thus determine the distribution of force and temperature.
