FiSpec FBG Interrogators

FBGX100 and FBGX400 Interrogators

FiSpec Interrogators

Interrogators for SM800 850nm FBG Sensor Chains

Depending on measurement requirements, a SM800 850nm  FBG sensor chain is interfaced with either a FiSpec® single channel FBGX100 or 4-channel FBGX400 interrogator. With their small form factor, these units integrate all the necessary components for analysis of the FiSens® sensor chains, up to 30 points per chain, for purposes of either temperature or strain measurement. For ease of interface, these interrogators both communicate and power via single USB 2.0 interface.
