Beijing Tongwei Sensing si155 1kHz-100nm fiber grating sensing demodulator fiber optic sensing demodulation equipment

1kHz-100nm fiber grating sensing demodulator | si155

si155 is an industrial-grade fanless fiber grating sensing demodulator. With both static and dynamic full spectrum analysis functions,si155 is equipped with a maximum of 4 channels,each channel has a bandwidth of 100nm,and can connect hundreds of sensors at the same time,making it suitable for long-term reliable and high-precision measurements.

si155 is equipped with a newly upgraded high-power,low-noise,ultra-wide-bandwidth sc laser light source. It uses fiber tunable Faber filter and wavelength reference technology to ensure the absolute wavelength accuracy of each scan.

The new generation HYPERION platform on which si155 is based has new groundbreaking features,such as high-performance DSP single-board computer and real-time FPGA processing. The si155 enables fast full-spectrum data acquisition with built-in flexible peak detection algorithms for Bragg gratings (FBG),long period gratings (LPG) and fiber optic Faber sensors (FP),enabling low-latency access to data in closed-loop feedback applications .
