FiSpec Interrogators
Interrogators for FiSens® Sensor Chains
Depending on measurement requirements, a FiSens® 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.
