    摘要： An electrical machine component monitoring system includes a light source that provides an optical signal through a fiber optic cable and a fiber optic sensing component positioned on the electrical machine component or at a standoff distance from the electrical machine component to obtain a responsive optical signal representative of a condition of the electrical machine component. The system further includes a photodetector to receive the responsive optical signal from the fiber optic sensing component and to convert the responsive optical signal to an electrical signal. A processing circuitry is also provided in the system for determining information regarding dirt on the electrical machine component by analyzing the electrical signal.

    摘要： A gas detection system is provided for identifying a gas. The gas detection system includes a sensing module with a hollow chamber enclosed by a chamber housing. Additionally, the sensing module includes an optical sensing fiber positioned within the hollow chamber. The optical sensing fiber includes a gas sensor including a fiber Bragg grating positioned at a grating location along the optical sensing fiber, and a sensing layer affixed to an exterior surface of the optical sensing fiber at the grating location. After the gas is directed into the hollow chamber, the sensing layer and the gas exchange heat energy, based in part on a heat transfer coefficient of the gas. The exchange of the heat energy induces a shift in a Bragg resonant wavelength of the fiber Bragg grating which exceeds a threshold shift required for detection, where the shift is used to identify the gas.
