    摘要: A vibration detector (1) comprising at least one fiber optic sensor (2) mechanically coupled to a flexible support member (3). The vibration detector (1) is mounted on the outside of the pipeline and a signal from the fiber optic sensor is measured. This signal is indicative of whether the vibration detector is experiencing vibrations due to collisions of contaminant particles with each other and/or with the walls of the pipeline. A method for detecting particulate contaminants in a fluid flowing in a pipeline is also provided.

    摘要: Apparatus for interrogating an optical fiber comprising a plurality of fiber Bragg gratings each having a resonant wavelength in a different discrete wavelength band. The apparatus comprises a delay arrangement interposed in use in an optical path for light supplied to and/or reflected from the fiber Bragg gratings. The delay arrangement is configured to apply a different time delay to light in each of the discrete wavelength bands, whereby the light reflected from each of the fiber Bragg gratings is received at an interrogator port of the apparatus in a different discrete time interval.

    摘要: A system for the structural monitoring of blades 1 on a wind turbine. Each blade 1 has respective optical fibre bragg grating sensors 5. The system has a number of input connectors, which connect to the strain sensors 5 of respective blades 1. A single output connector connects to a data processing device 3 which processes signals from the strain sensors 5. The input connectors each have a signal path to the output connector that is different in length to the signal path from the other input connectors, such that signals from a given blade 1 can be identified at the data processing device 3 by the time of arrival of the signals. The system has the advantage that the each of the blades 1, including the sensors attached to it or embedded within it can be identical and therefore interchangeable.
