T212/ Cryogenic Strain Sensor Datasheet

Key Features

Precise and repeatable strain measurements at cryogenic temperatures. The advanced unibody T212 micro-structured design for temperature compensated strain measurements in ultra-low temperature environments uses one precision-made FBG written into the fibers’ core and advanced materials technology for producing a transducer configuration of high resolution, precision, and repeatability. Standard and custom Reflectivity, SLSR & BW options are available.

Ready to be daisy-chained. 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 T212 strain sensors.

Field-proven with hundreds of completed installations. For demanding projects that require stable operation for the long term.


The T212 is a Single-Mode Fiber (SM) based advanced Fiber Bragg Grating (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 T212 Cryogenic Strain Sensor handling and installation is fast, easy and intuitive. Delivers the advantages inherent to FBG based sensors including immunity to lightning and electromagnetic interference (EMI). Spot-weldable version for operation from -270°C (~5K) to +120°C can be made available upon request. T212 series Surface 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.
