Abstract: A temperature sensing system is provided, including an optical temperature sensing probe; a cable coupled to the probe for interfacing the probe with a converter via a connector; an optical fiber carried through the cable from the probe; and a calibration module positioned in the probe or connector, wherein the connector comprises at least two electrical conductors to enable the calibration module to communicate with the converter via the connector. A connector is also provided for connecting an optical temperature sensing probe to a converter via a cable coupled to the connector, the connector including a bore for carrying an optical fiber from the cable to the converter; at least two contact points; and at least two electrical connections via the at least two contact points.

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.

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.

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.
