The Cryogenic Strain Sensor is a Single-Mode Fiber (SM) based advanced FBG Packaged Surface Strain Sensor for use in environments from -270°C (~5K) to +40°C.

ATEX compliant for use in explosive environments and packaged to operate at ultra-cold temperatures. Ready for direct mounting and 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 Cryogenic Strain Sensor handling, and installation are fast, easy and intuitive. Delivers the advantages inherent to FBG based sensors including immunity to lightning and electro- magnetic interference (EMI). Spot-weldable version for operation from -270°C (~5K) to +120°C can be made available upon request. The sensor packaging described herein represents the most popular configuration and can be customized.

Well suited for projects that include the need to monitor strain on structures at cryogenic temperatures at one or many locations. Provided as single connectorized sensors or can be configured at the factory in ready-to-install sensing arrays of various lengths and with a flexible number of strain sensors. Field-proven with hundreds of completed installations and appropriate for demanding projects that require long term stable operation.
