Abstract
A mount (20) for a temperature-compensated fiber optic strain gauge (10), the mount (20) comprising: a void (19) located at a middle portion of the mount (20) to separate the mount (20) into a first section (17) and a second section (18); and removable bridges (24) to connect the first section (17) to the second section (18); wherein after the mount (20) has been operatively attached to a host structure (5), the removable bridges (24) are removed.
Claims25
A mount for a temperature-compensated fibre optic strain gauge, the mount comprising:
- a void located at a middle portion of the mount to separate the mount into a first section and a second section;
- and
- removable bridges to connect the first section to the second section;
- wherein after the mount has been operatively attached to a host structure, the removable bridges are removed.
A temperature sensor for measuring the temperature of a host structure, the temperature sensor comprising:
- a mount to be operatively attached to the host structure;
- a recessed path defined on a surface of the mount having at least one straight section and at least one curved section;
- a fiber Bragg grating (FBG) recorded within a core of an optical fiber to measure temperature, the FBG being located within the straight section of the recessed path to ensure the FBG is kept straight;
- wherein the at least one curved section of the recessed path allows limited lateral movement of the optical fiber.
A mount for a temperature sensor, the mount comprising:
- a recessed path defined on a surface of the mount having at least one straight section and at least one curved section;
- wherein a fiber Bragg grating (FBG) recorded within a core of an optical fiber to measure temperature is located within the straight section of the recessed path to ensure the FBG is kept straight, and the at least one curved section of the recessed path allows limited lateral movement of the optical fiber.
