The T217 is a Single-Mode Fiber (SM) based Fiber Bragg Grating (FBG) Surface Strain Sensor with Self-Temperature Compensation for use in environments from -20°C to +120°C with rugged 3mm OD optical cable pigtails. 

Ready for direct mounting steel construction exhibiting excellent wavelength to strain linearity. Temperature compensated. 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 T217 sensor handling and installation is fast, easy and intuitive. Delivers the advantages inherent to FBG based sensors. Immune to lightning and electromagnetic interference (EMI). T217 series Surface Strain Sensors are fabricated using licensed and proprietary state-of-the-art laser manufacturing technologies.

Key Features:

Strain and temperature linearity. The T217 strain sensor design uses two precision made FBGs written into the fiberscore for producing a transducer configuration of high linearity, resolution, accuracy, and precision. Multiple Reflectivity, SLSR, & BW options available.

Rugged packaging format. The T217 sensor is well suited for precisely measuring strains in outdoor applications and can be manufactured with ultra-low bend radius fiber for meeting the needs of even the most demanding fiber routing applications. 

Pre-Strain level is set at the factory. The T217 pre-strain level can be factory set to accommodate any strain range within the strain limits of -2000ue to +7,000ue.

Spot-welded. The T217 is designed to be surface mounted by spot-welding. Epoxy installation or securing with screws is also possible. Installation video available upon request.

Ready to be daisy chained and field proven. Well suited for projects that include the need to monitor strain at one or many locations. Provided as single connectorized sensors or in ready to install arrays of various lengths and with a flexible number of sensors. For projects requiring stable operation for the long-term.
