The T290 is a Single-Mode Fiber (SM) based Fiber Bragg Grating (FBG) embedded in a bolt, yielding a commercially packaged Bolt Strain Sensor for measuring the tension in fasteners used for joining the components of a structure in environments from -40°C to +85°C.

Integrated into a small recess bored and threaded into the center of the head and shank of a bolt, rivet, stud, screws. Available in a wide range of optical specifications. The accuracy and precision specifications take into account any hysteresis, non-linearities, and the repeatability of the sensor. The T290 sensor installation is fast, easy, intuitive. Delivers the advantages inherent to FBG sensors. Immune to lightning and electromagnetic interference (EMI). T290 series Surface Strain Sensors are fabricated using licensed and proprietary state-of-the-art laser manufacturing technologies and a patented product design. The sensor packaging described herein is the most popular configuration and can be customized.
