Optical Sensing Instrument | si255 Description! Key Features! The si255 is an industrial grade, fan-less optical sensing interrogator based on the x55 core, which combines both static full spectrum and dynamic peak sensor measurement capabilities to provide long-term, reliable, accurate, and highly repeatable measurements of nearly 1000 sensors on 16 parallel, 160 nm channels.! Full spectrum at 1 kHz with 160 nm on 16 parallel channels simultaneously, eliminating the need for optical switches ! Leveraging the strengths of the new Micron Optics x55 core, the si255 Optical Sensing Interrogator features a high power, low noise, ultra wide swept wavelength laser, realized with Micron Optics patented Fiber Fabry-Perot Tunable Filter technology. The x55 interrogator core employs high performance onboard DSP peak detection, which allows for Static and dynamic rapid data acquisition of Fiber Bragg Grating measurements of (FBG), Long Period FBG, and Fabry-Perot (FP) FBG and FP sensors sensors. Additionally, the x55 interrogator employs high speed full spectral scanning and monitored simultaneously data acquisition, providing measurements with high absolute accuracy, high dynamic range performance and flexible post-processing. The combination of high speed, full spectral data, flexible peak detection and 160 nm wavelength range is simply unmatched in optical sensing. Dynamic sensor measurements in a single, continuous 26 dB dynamic range, available to each sensor on each channel, independent of differential system losses Data verification key guarantees only valid output. Each data set is calibrated and verified against any potential sources of system error (coming soon). Detailed optical spectrum enables versatile measurements of FBGs, LPGs and FP sensors Built on the proven reliability and longevity of the Micron Optics swept wavelength source, with over 100 million hours logged since 2000 ! The si255 interrogator is built upon the all-new HYPERION platform, which brings to the market a host of previously unrealizable capabilities: the latest in high-speed data collection and processing hardware; powerful, real-time FPGA processing for calibration and control; programmable peak fitting and tracking algorithms; and comprehensive API and example support for LabVIEW, Python, Matlab, and C++. The si255 offers a first glimpse of the exciting possibilities that the HYPERION platform will offer. Deployments!
