OS4100 : Temperature Compensation Sensor
The os4100 Temperature Compensation Sensor has a similar design and installation procedure to the os3100 Optical Strain Gage. When mounted in close proximity, it is a convenient choice for temperature compensation of the os3100. The os4100 Temperature Compensation Sensor is designed to make fiber handling easy and sensor installation fast and repeatable.
The os4100’s 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.
With each sensor, Luna provides a Sensor Information Sheet listing the 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.
