For a temperature measurement in areas having electromagnetic fields, shielding devices must be provided. According to the invention, at least one temperature sensor is designed as a fiber-optic sensor having Bragg gratings (FBG), wherein the sensor is arranged in a non-metallic housing (1) that precludes expansion effects for the individual FBG sensors (1, 1', 1' ', ...). Such a device can be used advantageously to measure the temperature distribution in oil sand deposits, for which purpose a suitable measuring arrangement is required. A measuring arrangement having several such devices forms a distributed temperature sensor (1, 1', 1", ...), wherein the devices are guided parallel to each other in holes (120, 120') of the deposit (100).

Les mesures de température dans des zones où sont présents des champs magnétiques nécessitent des dispositifs de protection. Selon l'invention, au moins un capteur thermique est configuré sous la forme d'un capteur à fibres optiques à réseaux de Bragg (FBG), le capteur étant disposé dans un boîtier non métallique (1) qui exclut les effets de dilatation des différents capteurs FBG (1, 1', 1'',...). Un tel dispositif peut être utilisé avantageusement pour mesurer la répartition thermique dans les gisements de sable bitumineux, ce qui nécessite un système de mesure approprié. Un système de mesure comportant plusieurs dispositifs de ce type constitue un capteur thermique réparti (1, 1', 1'',...), les dispositifs étant guidés parallèlement les uns aux autres dans des trous (120, 120') du gisement (100).
