Name: Luna os3310 Optical Strain Rosette FBG Sensor
Brand: Luna
SKU: os3310

Overview

The Luna os3310 is a fiber Bragg grating (FBG) based strain rosette sensor in the os3300 Optical Strain Rosettes series by CMIWS. It has three active strain elements oriented at 0°, 45° and 90°. The sensors have a low profile and can be distributed over distances of up to 10 km.

The sensor is designed for compact, spot-weldable strain measurement on a 304 stainless steel carrier. A mounting plate fixed to the sensor guides the installer, so installation is simple and repeatable. The measurement range is -1,800 to 1,800 με. Unlike the os3320, the os3310 has no temperature compensation element.

The os3310 can run on the same instrumentation platform as sensors for other physical parameters, such as temperature, displacement, acceleration, tilt and pressure. A single Luna HYPERION interrogator supports up to 96 os3310 sensors, with 6 sensors per channel.

Software

The os3300 series works with ENLIGHT Sensing Analysis Software, which provides tools for data acquisition, computation and analysis of optical sensor networks. The sensors also work with the HYPERION platform's Application Programming Interface (API), which includes examples in LabVIEW, Python, Matlab, C++ and C#.
