The Surface Strain Sensor is a Single-Mode Fiber (SM) based FBG based Packaged Surface Sensor for use in environments from -20°C to +60°C.

Available in a wide range of optical specifications. Packaged to eliminate influences from the ambient environment. Ready for direct mounting steel construction exhibiting excellent wavelength to temperature linearity. Calibration service available upon request. The full-scale (FS) accuracy and precision specifications take into account any hysteresis, non-linearities, and the repeatability of the sensor. The sensor handling, and installation is fast, easy and intuitive. Delivers the advantages inherent to FBG based sensors. Immune to lightning and electromagnetic interference (EMI).

The sensor packaging described herein represents the most popular configuration and can be customized. The specific strain sensor includes an actual second absolute FBG temperature sensor embedded in its construction and serving as both precise temperature compensator and as an independent absolute temperature sensor. Well suited for projects that include the need to monitor strain and temperature at one or many locations. Provided as single connectorized sensors or in ready to install arrays of various lengths and flexible number of sensors. It can be surface mounted using mounting screws, spot-welding, or by chemical (glue) bonding. Installation procedure provided with each sensor.
