Description

The MuST FBG deformation sensors are transducers that transform a static or dynamic distance variation into a change in reflected wavelength of a pre-stressed Fiber Bragg Grating that can be measured with SMARTEC Reading Units.

The sensor is composed of an active and a passive part. The active part contains the measurement fiber and measures the deformations between its two ends, transforming it into a wavelength shift of the Fiber Bragg Grating. The passive part is insensitive to deformations and is used to connect the sensor to the Reading Unit. In the passive part of the sensor, it is possible to install a loose Fiber Bragg Grating for temperature sensing and compensation.

The sensors are available in single-ended, double-ended and chained configuration. Using our Readout Units it’s possible to connect up to 7 full-range temperature compensated sensors on the same channel (or up to 4 with temperature compensation + 4 without). The sensors are terminated with E2000-APC connectors or on user‘s specifications.

The sensors can be quickly and easily installed without affecting the construction schedule. They can be directly embedded in concrete and mortars, or surface mounted.
