Overview
The ODiSI 6101 belongs to the ODiSI 610x models of the Luna ODiSI 6000 Series of optical distributed sensor interrogators. Luna lists this product as discontinued and names the ODiSI 7100 Series as its replacement.
The ODiSI 6000 Series instruments are high-definition fiber optic sensing (HD-FOS) interrogators. They work with sensors made from unaltered optical fiber and measure Rayleigh backscatter. This lets them record strain and temperature at thousands of points per meter of sensing fiber, mapping the strain contour of a structure under test or the continuous temperature profile of a process.
Measurement modes
The ODiSI 610x models can be set to measure strain or temperature with a gage pitch of 0.65 mm, 1.3 mm, 2.6 mm or 5.2 mm. They also work with continuous fiber grating (CFG) sensors, which tolerate vibration better and give improved dynamic performance. With the optional Extended Range Remote Modules, a channel supports sensors up to 100 m long and a strain-compensated temperature mode for surface-mounted and embedded HD-SC sensors.
Software and integration
The system comes with an instrument controller running the ODiSI application software. The software identifies sensors automatically and handles configuration, triggering, data logging, replay and export. Data can be streamed in real time over Ethernet in a JSON-based format. The system supports IEEE 1588 PTP time synchronization, a TTL sync output and start/stop triggering. ODiSI Remote software for Windows and Linux provides remote control and viewing, and the optional 3DViz software maps data onto 3D CAD models or 2D images.
