Optical Transducer comprises at least one Optical waveguide, at least one Sensing Element, an element of Passageway designed to isolate a first portion of the Transducer in communication with the Sensing element of the Transducer against a second portion that contains the element DetectionWhere the element of pathway Step comprises at least a First Seal and a Second Seal; Ensemble Associated Pathway step.

摘要

An optical transducer is provided. A measuring portion of the transducer may be exposed to a high pressure and fluids when the optical transducer is deployed (e.g., in a wellbore or other industrial setting). The transducer may include an optical waveguide with a first portion that forms a first seal that isolates an instrumentation portion of the transducer from exposure to the high pressure and fluids to which the measuring portion may be exposed. The transducer may also include a second seal with a stack of material elements that contact a second portion of the optical waveguide to also isolate the instrumentation portion of the transducer from exposure to the high pressure and fluids to which the measuring portion may be exposed.
