Fiber-Optic Thermosensor Based on Shape Memory Effect
Moscow Engineering Physics Institute, Dep. of Solid State Physics, Kashirskoe shosse 31, 115409 Moscow, Russia
A fiber-optic thermosensor using thin shape memory ribbons of rapidly quenched TiNiCu alloy as thermosensitive element is described. It is shown that the developed thermosensor is optically passive, resistant to corrosion and to radio and electromagnetic noise. Also it has a fast response (less than 1 sec), a high reliability and durability (more than 105 cycles), a small size and high simplicity of thermosensitive part. Its switching temperature can be varied in a wide region (273-353 K) with alloy composition.
