Temperature Monitoring in the Refractory Lining of a Continuous Casting Tundish Using Distributed Optical Fiber Sensors

Distributed fiber optic sensors for applications in electric arc furnaces

“…For this work, we used the Luna ODiSI 6100 system for the signal interrogation. By analyzing the backscattered light, the local spectral shift (Δλ) due to temperature changes is expressed as [16]:…”

“…(OFDR), among others, have opened new avenues for in-situ chemical composition analyses, distributed strain and temperature monitoring in various steel industry's operation monitoring [11] [12][13] [14][15] [16] [17]. FOS is particularly suitable for sensing in steel-making applications due to its capability for distributed sensing, and immunity to electromagnetic interference (EMI) and corrosion, common in steel-making facilities [18] [19].…”

High Precision Raman Distributed Fiber Sensing Using Residual Composite Dual-Convolutional Neural Network

“…Compared to other distributed optical fiber sensing systems, it has the rapid measurement rate and the straightforward design [13]. The use of Raman distributed optical fiber sensing in pipeline leakage detection [14], power cable monitoring [15], [16], fire alarm systems [17], and other distributed temperature monitoring fields [18], [19], [20] is gaining widespread attention. The performance metrics for the Raman distributed fiber sensing system mainly include temperature measurement accuracy and precision [21], sensing distance [22], and spatial resolution [23].…”
