FS42 – Portable BraggMETER

Optical Interrogator with Embedded Software

FS42 Portable BraggMETER is an optical interrogator with embedded software specifically designed to interrogate Fiber Bragg Grating (FBG) based sensors on field.

With a built-in touchscreen interface and rechargeable batteries operation this is a unique product in the market that perfectly fits on site installation activities or short tests.

BraggMETER interrogators employ proven continuous swept laser scanning technology. They include a NIST traceable wavelength reference that provides continuous calibration to ensure system accuracy over long term operation.

The high dynamic range and output power allow high resolution to be attained even for long fiber leads and lossy connections.

The Portable optical interrogators meet the required reliability and versatility to be used in both laboratory testing and field deployment in Civil, Aeronautics, Energy and R&D.
