FBG Interrogators Description

FBG Interrogators are high-precision measuring instruments for signal obtaining and processing from FBG sensors under operating conditions. Optromix interrogators can control up to 8 optical channels. FBG interrogators can operate with maximum 20 sensors per channel. The device is controlled by the PC with the specialized software for sensors monitoring. The system contains a broadband source of radiation and it can carry out spectrum analysis.
