Characteristics:

• 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.
• Self-referenced. Based on the measurement of an absolute parameter - the Bragg wavelength - independent of power fluctuations.
