The Mini Surface Strain Sensor is a Single-Mode Fiber (SM) based FBG Mini Packaged Surface Sensor for use in environments from -20°C to +120°C.
Available in a wide range of optical specifications. Ready for direct mounting steel construction exhibiting excellent wavelength to strain linearity. The full-scale (FS) accuracy and precision specifications take into account any hysteresis, non-linearities, and the repeatability of the sensor. The sensor handling, and installation are fast, easy and intuitive. Delivers the advantages inherent to FBG based sensors. Immune to lightning and electromagnetic interference (EMI).

The sensor packaging described herein represents the most popular configuration and can be customized. The Mini Surface Strain Sensor design for both temperature and strain measurements use a precision-made FBG written into the fibers’ core for producing a transducer configuration of high linearity, resolution, accuracy, and precision. It is well suited for precisely measuring strains in small spaces and can be manufactured with ultra-low bend radius fiber. The Mini Surface Strain Sensor pre-strain level can be factory set to accommodate any strain range within the strain limits of -2000 µε to +7,000 µε. Typically, it is set for the whole range.

Well suited for projects that include the need to monitor strain at one or many locations. Provided as single connectorized sensors or in ready to install arrays of various lengths and with a flexible number of sensors. For demanding projects that require both low cost per sensing point and stable operation for long-term.
