FS62: High Performance Fiber Bragg Grating (FBG) Strain Sensors
FS62 Athermal Strain Sensor
The FS62 – Athermal Strain Sensor is a Fiber Bragg Grating (FBG) based sensor with an innovative proprietary design that ensures athermal operation of the strain gauge by cancelling the intrinsic fiber optic thermal sensitivity (standard option).
The measurement of temperature for the compensation of cross-sensitivity is, therefore, not necessary. This benefits large scale system design and overall performance.
The FS62 – Athermal Strain Sensor can be designed to be bonded onto different structures or components made of several material.
- Intrinsic athermal design
Possible adjustment to further compensate for the thermal expansion of a given structure, thereby enabling stress and load-induced strain components to be measured.
- Completely passive
Inherent immunity to all electromagnetic effects (EMI, RFI, sparks, etc.) and safe operation in hazardous environments.
- High multiplexing capability
Connection of a large number of sensors to a single optical fiber, reducing network and installation complexity.
- Remote sensing
Large distance between sensors and interrogator (several kilometers).
- Compatible with most interrogator
Provided with calibration sheet, allowing easy and accurate configuration.
Based on the measurement of an absolute parameter – the Bragg wavelength – independent of power fluctuations.
