Datasheet
Description：
The T211 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.
Ultra-small packaging. Available in a wide range of optical specifications. Ready for direct mounting steel construction exhibiting excellent wavelength to strain linearity. Temperature-compensated. Calibration service available upon request. The fullscale (FS) accuracy and precision specifications take into account any hysteresis, non-linearities, and the repeatability of the sensor. The T211 sensor handling and installation is fast, easy and intuitive. Delivers the advantages inherent to FBG based sensors. Immune to lightning and electromagnetic interference (EMI). T211 series Surface Strain Sensors are fabricated using licensed and proprietary state-of-the-art laser manufacturing technologies and product designs. The sensor packaging described herein represents the most popular configuration and can be customized.
Key Features：
Strain and temperature linearity. The T211 strain sensor design uses two precision made FBGs written into the fibers’ core for producing a transducer configuration of high linearity, resolution, accuracy, and precision. Multiple Reflectivity, SLSR, & BW options available.
Ultra-small packaging format. The T211 sensor is well suited for precisely measuring strains in small or confined spaces 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 T211 pre-strain level can be factory set to accommodate any strain range within the strain limits of -2000ue to +7,000ue. Typically it is set for the whole range.
Spot-welded. The T211 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. 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.
Field proven. For demanding projects that require stable operation for the long-term.
