Fiber optic linear displacement sensor is ideal for real-time monitoring of civil engineering structures, structural monitoring of aircraft, both in-flight and on-ground, smart structures instrumentations, concrete structures and other industrial applications where long term. Fiber optic linear displacement sensor is ideal for real-time monitoring of civil engineering structures, structural monitoring of aircraft, both in-flight and on-ground, smart structures instrumentations, concrete structures and other industrial applications where long term. Fiber optic linear displacement sensor is ideal for real-time monitoring of civil engineering structures, structural monitoring of aircraft, both in-flight and on-ground, smart structures instrumentations, concrete structures and other industrial applications where long term reliability is. Probe tips are immersed in LOX at -300°F and 1,000 psi. Why Use Fiber Optic Displacement Sensors?Optical Fiber Displacement Sensors (OFDSs) provide several advantages over conventional sensors, including their compact size, flexibility, and immunity to electromagnetic interference. These features make OFDSs ideal for use in confined spaces, such as turbines, where direct laser access is. Optical Displacement Sensor for measuring relative displacements between two surfaces. Our modular (interchangeable) non-contact fiber optic sensors systems have dual channel that enables the user to make simultaneous. MTI Instruments provides high-performance fiber optic sensors and probes engineered for applications requiring large measurement ranges and extended standoff distances.
