Accelerometer | os7100

Applications

•t Measurement of acceleration on large
structures from DC to low frequencies.

•t Continuous lifetime health monitoring
of bridges, dams, buildings, tunnels,
ships, aircraft, trains, and other complex
structures.
Features

•t Qualified to same rigorous standards applied to comparable electronic gages.

Description
The os7100 is a fiber optic accelerometer based on Fiber Bragg Grating (FBG) technology.
Optimized for large structures and long term measurements, the os7100 measures accelerations from DC up to a few hundred Hertz. Like most conventional accelerometers, the os7100
can be attached to a structure using a standard threaded connection, and is available in one,
two or three axis configurations. A rugged, sealed metallic body, armored cables, available
weatherproof junction boxes and connector protection fittings make the os7100 ideal for
outdoor installations on exposed structures.

•t Cable integrated with sensor package for
fiber protection and strain relief.

•t Standard threaded connection to structure
for fast, simple, repeatable installation.

•t Available mounting block for two and
three axis applications.

os7100 - Single Axis Accelerometer

•t Connector protection fittings available for
harsh environments.

•t Armored fiber cable and rugged sensor
package.

•t Micron Optics’ patented micro optomechanical technology.

For low frequency signals, the os7100 yields measurements that are as accurate and stable as
conventional accelerometers and offers the added benefits of EMI immunity and lightning/
corrosion resistance that are needed for long term outdoor installations. Additionally, the
os7100 is inherently compatible with FBG based strain and temperature sensors, thereby
enabling comprehensive fiber-based sensing networks.

os7100 - Three Axis Accelerometer

The os7100’s single-ended design is ideally deployed in coupled-star sensor network architectures, thus maximizing overall sensor capacity on each optical sensing interrogator channel.
Installation and cabling requirements for these types of fiber arrays are much less expensive
and easier to manage than those of conventional electronic sensor networks.

Products displaying the “Micron Optics Tuned” logo include Micron Optics tunable technologies ensuring high quality and performance.
