Fiber Optic Displacement Sensor Series Products

Fiber optic displacement sensors are precision instruments that measure linear or angular displacement using light, offering high reliability in harsh or compact environments.Overview of Fiber Optic Displacement SensorsFiber optic displacement sensors use light transmitted through optical fibers to detect changes in position or displacement. They are widely used in industrial automation, aerospace, civil engineering, and structural health monitoring due to their non-contact measurement, immunity to electromagnetic interference, and suitability for harsh environments (Keyence) .Key TechnologiesFiber Bragg Grating (FBG) Sensors: These sensors incorporate FBGs inside the fiber core, acting as reflectors that measure strain, temperature, or displacement. FBG arrays allow multiple sensors to operate in series along a single fiber, enabling distributed sensing over long distances (DirectIndustry) .WLPI-based Sensors: Used in geotechnical, aerospace, and transportation applications, these sensors provide real-time monitoring of structures and aircraft, offering long-term reliability (Opsens) .Interferometric and Laser-based Sensors: Some series, like the PICOSCALE Interferometer, use focused or line-focused beams for precise displacement measurement of small or cylindrical targets (DirectIndustry) .Product Series and FeaturesPhiltec D and RC SeriesDesigned for high-precision displacement measurement in industrial and research applications.Standard fiber optic cable length: 914 mm (3 feet), with options for customization.Includes DMS Control Software for data acquisition at up to 10,000 samples/sec.Supports multi-channel enclosures with up to 8 D-type or 5 RC-type sensors (Philtec) .Flexible, semi-crush-proof cables suitable for high-pressure, twisting, and cryogenic environments.Opsens Fiber Optic Linear Displacement SensorsIdeal for civil engineering, aerospace, and smart structures.Provides real-time monitoring with high reliability.Suitable for both in-flight and on-ground aircraft monitoring (Opsens) .HBK Fiber Optic SensorsUtilize FBG technology for linear displacement measurement.Rugged design with temperature compensation, suitable for structural health monitoring (HBK) .Keyence Fiber Optic SensorsComprise an amplifier and sensor heads connected via fiber units.Non-contact detection using LED light, capable of detecting a wide variety of materials including metals, plastics, and liquids.Compact heads allow installation in tight spaces, resistant to temperature, vibration, and fluids (Keyence) .Detection methods include through-beam, reflective, retro-reflective, and definite-reflective.ApplicationsIndustrial Automation: Detecting position, presence, or movement of components in assembly lines.Aerospace and Defense: Monitoring aircraft structures, rotor blade clearances, and vibration analysis.Civil Engineering: Structural health monitoring of bridges, concrete structures, and smart infrastructure.Harsh Environments: High-temperature, high-pressure, or electromagnetic interference-prone areas.AdvantagesNon-contact measurement reduces wear and maintenance.High-speed response and precision.Immune to electromagnetic interference.Flexible installation in confined or hazardous locations.Capable of multi-sensor arrays for distributed measurements.
