T240 Rebar Embedded Strain Sensor
Description
The T240 is a Single-Mode Fiber (SM) based Long-Gauge Fiber Bragg Grating (FBG) Strain Sensor for placing in-line with rebars prior to their embedding into concrete. The T240 is designed for being placed truly in-line with the customers’ rebars for the accurate measurement of rebar strain after embedding into concrete. Packaged to eliminate influences from the ambient environment. Excellent wavelength to temperature linearity. The accuracy and precision specifications take into account any hysteresis, non-linearities, and the repeatability of the sensor. The T240 sensor handling and installation is fast, easy and intuitive. Immune to lightning and electromagnetic interference (EMI). T240 series Long-Gauge 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.
