os3300 Optical Strain Rosettes by CMIWS

Luna’s os3300s are fiber Bragg grating (FBG) based strain rosette sensors. Featuring simple integration, low profile sensors that can be dispersed over up to 10km, with 3 active strain elements (0°/45°/90°) for the most robust sensor coverage on the market.

The os3300 features a novel approach to compact spot weldable strain measurements, all while being able to pair with various physical parameters e.g. temperature, displacement, acceleration, tilt, pressure.

Installation is simple and repeatable with a mounting plate affixed on the os3300 to help guide the installer. With strain ranges of -1,800 to 1,800 με, and available integratd temperature compensation, the os3300 series presents a unique capability for sensor deployments. Up to 96 os3300 sensors can be integrated on Luna’s HYPERION platform.

The os3300 series of sensors is compatible with ENLIGHT Sensing Analysis Software, which provides an integrated suite of tools for data acquisition, computation and analysis of optical sensor networks as well as the HYPERION platforms comprehensive Application Programming Interface (API) and examples written in LabVIEW, Python, Matlab, C++ and C#.
