Datasheet
Description：
The T430 is a Single-Mode Fiber (SM) based Fiber Bragg Grating (FBG) based Packaged Displacement Sensor for use in environments from -20°C to +60°C.
Available in a wide range of optical specifications. Packaged to eliminate influences from the ambient environment. Ready for direct mounting steel construction exhibiting excellent wavelength to displacement linearity. 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 T430 sensor handling and installation is fast, easy and intuitive. Delivers the advantages inherent to FBG based sensors. Immune to lightning and electromagnetic interference (EMI). Rugged construction.
T430 series Displacement 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：
Displacement and temperature linearity. The unibody 430 design for both displacement and temperature measurements uses precision made FBGs written into the fibers’ core for producing a transducer configuration of high linearity, resolution, accuracy, and precision. SLSR & BW options.
Absolute temperature sensor included. The T430 displacement sensor includes an actual second absolute FBG temperature sensor embedded in its construction and serving as both precise temperature compensator and as an independent absolute temperature sensor.
Zero displacement level is adjustable during installation. Field adjustable range between -40mm to +40mm and 0 to 80mm to the application requirements.
Ready for multiplexing in star architecture. Well suited for projects that include the need to monitor displacement at more than one location, using the same monitoring instrument channel. Provided as single connectorized sensors or in ready to install star networks of various lengths and with a flexible number of sensors.
Multiple installation options. The T430’s brackets are typically installed using welding, mounting screws, or by chemical (glue) bonding. Sensors have M6x0.5 & M16x1.5 threads for mounting.
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 projects measuring dilations, soil and other materials settlements, rock movement and crack monitoring, and as borehole extensometers, since 2012.
