Flexible temperature probe

An assembly, comprising:

• a body including a channel having at least one bend, the channel ending at a surface;
• a temperature probe, comprising:
• a plurality of fiber optic elements;
• a sensing sub-assembly having a first and a second end, the first end connected to a distal portion of the plurality of fiber optic elements;
• and
• a flexible jacket surrounding the plurality of fiber optic elements and secured to the sensing sub-assembly to prevent relative movement between the flexible jacket and the sensing sub-assembly, the temperature probe being positioned within the channel and passing through the at least one bend so the sensing sub-assembly is in thermal communication with the surface.

A fiber optic temperature probe, comprising:

• a bundle of fiber optic elements having a first end and a second end;
• a collar having a first internal passage, the collar being secured to at least one of the first end and the second end of the bundle of fiber optic elements within the first internal passage;
• and
• a sensing sub-assembly including a first part and a second part, the first part including:
• a second internal passage for receiving the collar, wherein the first part of the sensing sub-assembly is secured to the collar within the second internal passage;
• a flexible jacket surrounding the bundle of fiber optic elements;
• and
• a projection formed on the collar, wherein the projection is configured to be secured to a portion of the flexible jacket, and wherein the second part includes a sensing element.
