OPTICAL TRANSDUCER WITH INTEGRATED FEEDTHROUGH

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.

1. A feedthrough assembly, comprising:
at least one conductive line; and a feedthrough element configured to isolate a first portion of the feedthrough assembly from a second portion of the assembly, wherein the feedthrough element comprises:
a housing having a bore extending therethrough;a first seal formed by a first portion of the at least one conductive line in contact with a mating surface of the bore of the housing; anda second seal formed by contact between an arrangement of sealing elements with a second portion of the at least one conductive line and an inner surface of the housing.
