AGTR-NEO FBG Interrogator
DO-160G qualified eight-channel Fiber Bragg Grating interrogator for aerospace and defense, with onboard processing, 256 GB of storage and an ARINC 801 optical interface. Distributed in the US by Sensuron.
Technical overview
The AGTR-NEO is a standalone multi-channel FBG interrogator built for airborne and harsh-environment use. It supports eight optical channels with up to eight FBG sensors each, sampling at 19.2 kHz on a single channel or 50 Hz across all eight, and carries an integrated single board computer for onboard data processing and 256 GB of storage. Data leaves over Ethernet as TCP or UDP with NTP-synchronised RTC timestamping. The unit is IP65 rated, weighs 700 g, measures 150 x 125 x 58.5 mm as a base system and operates from -10 degC to 70 degC.
Also supplied through PhotonFirst. The same instrument reaches us by more than one route; the specifications are the manufacturer's either way.
