Click here to download the Datasheet

Description

The T245 is a Single-Mode (SM) Fiber Bragg Grating (FBG) based Short-Gauge (11cm) Strain Sensor for embedding into concrete and other materials.

Packaged to eliminate influences from the ambient environment. The short-gauge length defined by the sensor’s anchoring brackets yields immunity to local defects or inhomogeneities of the tested specimen. Excellent wavelength to strain and temperature linearity. Calibration service available upon request. The accuracy and precision specifications take into account any hysteresis, non-linearities, and the repeatability of the sensor.

The T245 sensor handling and installation is fast, easy and intuitive. Immune to lightning and electromagnetic interference (EMI). T245 series Short-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.

Key Features

Strain and temperature linearity. T245 design uses one precision made FBG for producing a transducer with high linearity, resolution, accuracy, and precision. SLSR & BW options. If needed, temperature compensation is available using a separate, in-line T8XX series temperature sensor.

Rugged, small-sized, and pre-strained at the factory. Ready to be embedded into concrete without the need for any supporting brackets or fixtures.

Ready to be daisy-chained. Well suited for projects that include the need to monitor strain at one or many locations. Provided as single sensors or in ready to install arrays of various lengths and with a flexible number of sensors. The interconnections between adjacent sensors in the arrays can be via rugged waterproof connectors (T960) or by rugged waterproof splices (T970).

Low cost and field proven. For demanding projects that require both low cost per sensing point and stable operation for long-term. Extensively used in field applications since 2010.

Applications in Civil Engineering, Geotechnical, Energy, Industrial, and Research
