Sensor Measurement System - FBG-SCAN 700/800

The FBG-Scan 700 and 800 from FBGS are dynamic, high precision measurement systems for Fiber Bragg Grating (FBG) sensors. The system can measure up to 40 FBG sensors using two input channels. Both input channels are simultaneously monitored using an optical coupler at a scan rate up to 2000 Hz.

The FBG-Scan 700 and 800 are supplied along with ‘Illumisense’ V2.2 measurement software.
