  • Publication number: 20210080328
    Abstract: There is provided a fiber optic temperature probe having a base, a first tube connected to the base, a second tube provided coaxially within the first tube, a probe tip extending through an opening in a distal end of the first tube; and an optical fiber extending from within the base through an opening in the proximal end of the first tube and being substantially coaxial with respect to the first tube. There is also provided a fiber optic temperature probe having a base, a first tube connected to the base, a probe tip extending through an opening in a distal end of the first tube, an optical fiber extending from within the base through an opening in the proximal end of the first tube and being substantially coaxial with respect to the first tube, and a first lens positioned between the probe tip and the optical fiber.

  • Publication number: 20200393307
    Abstract: There is provided a temperature sensor comprising: an optical fiber; and a sensing element spaced from the optical fiber; wherein the optical fiber is aligned with the sensing element to deliver a source beam to interact with the sensing element and detect a return beam, the return beam exhibiting a temperature dependent property that is measured to determine a temperature of a measured object thermally coupled to the sensing element.

  • Publication number: 20200393308
    Abstract: The description pertains to an optical temperature sensor probe having a shaft and a tip. The shaft houses the optical fibers while the tip is made of a thermally conductive material and includes a sensing material therein. The sensing material is in optical communication with the optical fibers of the shaft, however the shaft is spaced from the tip to reduce heat transfer from the tip to the shaft. Furthermore, the sensing material is sealed from the surrounding atmosphere to protect it therefrom. In a preferred embodiment, a window is hermetically sealed to the tip to isolate the sensing material from the environment surrounding the probe.
