FBG Sensors, os12100

Product catalog summary

Applications

Fundamental optical element for fiber optic sensors measuring strain, temperature, displacement, pressure, and acceleration.
Measurement of strain on a structure’s surface and inside composite or laminate structures.
Demonstration and proof of concept for FBG multiplexing and sensor applications.
Experimental mechanics evaluations requiring multiple sensors.

Description

The os1200 Fiber Bragg Grating (FBG) Array is a six-meter-long polyimide-coated optical fiber with five FBGs spaced at one-meter intervals. FBGs are invisible reflectors set to specific wavelengths, shifting in response to strain or temperature changes. The os1200 is designed for various applications, from basic experiments to complex transducer construction, with excellent strain transfer and temperature performance due to its polyimide coating.

Features

Optional FC/APC connector and loose buffer tube for easy handling.
Clearly marked FBG locations and splice-free array.
Non-metallic construction.

Advantages of FBG Sensor Technology

Longevity: Resistant to lightning, corrosion, and EMI.
Passive: No spark hazard or power at the sensor.
Multiplexing: Supports many sensors with few cables over long ranges.
Versatility: Small size, capable of sensing multiple properties.
Installation: Can be welded, glued, embedded, or connected in series.
No user calibration required.
Ruggedness: Withstands over 100 million cycles and a wide temperature range.

The osl 200 Fiber Bragg Grating (FBG) Array is designed for use in fiber optic sensing applica- tions. It is a six meter long polyimide coated optical fiber with five FBGs spaced at one meter Fiber Bragg gratings are the fundamental elements upon which most fiber optic sensors are based. An FBG is an invisible reflector inside the core of the fiber that is set to a specific wavelength of light. When the fiber where an FBG is located is exposed to strain or tempera- ture, the FBG's "center wavelength" shifts to a higher or lower wavelength. The direction and magnitude of the shift is proportional to the change in strain or temperature. Each osl 200 is built with five FBGs at standard center wavelengths. osl 200 FBG array with optional FC/APC connector os1200's are used in applications ranging from basic experiments with FBGs to construction of complex transducers containing one or more FBGs. The polyimide coating provides excel- lent transfer of strain through the fiber coating to the FBG in the fiber core. Polyimide also performs well over a wide temperature range. The splice free array provides a convenient way to take advantage of the multiplexing capabilities of FBGs. One or two FC/APC connectors, and loose buffer tube protection, are available as packaging
