Optical Strain Gage

基于光纤布拉格光栅（FBG）技术，OS3200具有自粘背衬，其将传感器体保持在适当位置并在注射环氧树脂时保护FBG。环氧树脂包封了FBG并将其粘在结构的表面上。安装时间只是几分钟。在室温下在24小时后，可以在环氧树脂固化后进行测量。

与箔应变计的并排比较，OS3200同样敏感和准确，同时提供更大的应变范围和100倍的疲劳寿命。OS3200应变计是有资格用于温和环境中的使用，并提供基于FBG的传感器固有的许多优点。

This sensor can be used alone or in series as a part of an FBG sensor array. Multiple optical strain gages can be arranged in close proximity at 0, 45 and 90 degrees for strain rosette measurements. With each sensor, Luna provides a Sensor Information Sheet listing the gage factor and calibration coefficients needed to convert wavelength information into engineering units. The ENLIGHT Sensing Software provides a utility to calculate and then record, display, and transmit data for large networks of sensors.
