The optical source is a dual-wavelength light-emitting diode (LED). The sensing probe incorporates five pairs of double-wavelength fiber Bragg gratings along a single fiber for measuring axial pressure and temperature simultaneously in oil and gas pipelines. A linear CCD array based spectrometer is used for tracing the wavelength shift of the Bragg grating sensors. The tests were carried out in oil and gas pipelines, pressure resolution is 0. 1 Psi, and temperature resolution is 0. 1 °C .The measurement range of pressure and temperature is 0—1 OOMPa and -20—1 80 C respectively.","is_dataset_classified":null,"base_score":2.70805020110221,"endowment":2.70805020110221,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19767382","pmcid":null,"openalex_id":"https://openalex.org/W2111386033","authors":[],"funders":[],"total_grants":0,"fwci":1.0651,"citation_percentile":0.75254716,"influential_citations":0,"citation_trend":[{"year":2017,"count":1},{"year":2019,"count":1},{"year":2020,"count":3},{"year":2021,"count":2},{"year":2023,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://doi.org/10.1117/12.475573","host_type":"journal"}],"fields_of_study":["Advanced Fiber Optic Sensors","Photonic and Optical Devices","Analytical Chemistry and Sensors","Materials Science","Engineering","Environmental Science"],"mesh_terms":[],"keywords":["Fiber Bragg grating","Materials science","Optics","Temperature measurement","Fiber optic sensor","Spectrometer","Optical fiber","Wavelength","Pressure measurement","Grating","Optoelectronics","PHOSFOS","Dispersion-shifted fiber","Physics"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Affordable and clean energy"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-06T18:58:47.652896Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
