Frequently Asked Questions

The os3200 is suitable for use in structures (bridges, dams, tunnels, mines, buildings, oil platforms), energy (wind turbines, oil wells, pipelines, nuclear reactors, generators), transportation (railways, trains, roadways, specialty vehicles, cranes), marine vessels (hull, deck, cargo containers), aerospace (airframes, composite structures, wind tunnels, static and dynamic tests), and homeland security (perimeter intrusion, heat detection, security gate monitoring).

In side by side comparisons with foil strain gages, the os3200 is equally sensitive and accurate, while providing for greater strain range and 100 times more fatigue life. This sensor can be used alone or in series as a part of an FBG sensor array. Installation and cabling for such arrays is much less expensive and cumbersome than comparable electronic gage networks.

With each sensor, Micron Optics provides a Sensor Information Sheet listing the gage factor and calibration coefficients needed to convert wavelength information into engineering units. Micron Optics’ ENLIGHT Sensing Software provides a utility to calculate and then record, display, and transmit data for large networks of sensors.

The os3200 has a self-adhesive backing that holds the sensor body in place and protects the FBG while epoxy is injected. The epoxy encapsulates the FBG and bonds it to a structure’s surface. Installation time is just a few minutes. Measurements can be taken after the epoxy cures in 24 hours at room temperature.

The os3200 is a small, non-metallic optical, epoxy-mounted strain gage based on fiber Bragg grating (FBG) technology.
