strain gauge with fiber Bragg grating / single-axis
with fiber Bragg grating
The os4100 is specifically designed to provide temperature compensation data for strain measurements from FBG based strain gages installed on the same structure. Because its installation procedure is similar is to the os3100 Optical Strain Gage, it is a convenient choice for compensation of the os3100. It is also compatible with the os3200 Optical Strain Gage. The os4100 Temperature Compensation Sensor is designed to make fiber handling easy and sensor installation fast and repeatable. It is based on fiber Bragg grating (FBG) technology.
The os4100s stainless steel carrier holds the FBG in tension and protects the fiber during installation. Since there are no epoxies holding the fiber to the carrier, long term stability is ensured by design. The universal attachment feature on the os4100 carrier design allows fastening by weld, epoxy or screw.
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. The os4100 Temperature Compensation Gage is qualified for use in harsh environments and delivers the many advantages inherent to all FBG based sensors.
