CARACTÉRISTIQUES PRINCIPALES
Un capteur de température à fibre optique polyvalent conçu pour une large gamme d'applications, en particulier pour une utilisation dans des applications exigeantes. Le capteur offre une immunité complète aux RFI, EMI, NMR et aux radiations micro-ondes. Le capteur de température standard a un temps de réponse de 0,2 s. Avec un écart type de +/-0,2 °C, il permet des mesures précises et reproductibles. Le revêtement du capteur de température est en PTFE, et la pointe de la fibre a un diamètre de 1,7 mm avec un revêtement en polyimide robuste et un connecteur ST en acier inoxydable. Pour la stabilité mécanique et les applications par exemple dans le pétrole, des revêtements de protection spéciaux et des tuyaux sont disponibles. La sonde à fibre optique se compose d'une fibre de verre protégée par PTFE et d'un cristal de GaAs (Arséniure de Gallium) à la pointe du capteur.
