DTS-BLY-5S(ADV-10km) · Multimode 10 km DTS
10 km multimode sensing for power tunnels, utility corridors and industrial fire monitoring.
DTS uses optical fiber as a continuous temperature sensor. Selected fire-suitable configurations up to 10 km and the fourth-generation 12 km configuration can apply the same sensing and installation principles to Fiber Optic Linear Heat Detection (LHD); alarm zones, thresholds, response, fault monitoring and fire-system interfaces must meet applicable fire-alarm requirements. Applicable EN 54-22 or GB 16280 product requirements and certifications such as CCCF depend on the final product and market. Existing 20/30 km long-range and oil/geothermal versions are not intended for this fire application.
DTS-BLY-5S(ADV-10km) 10 km Distributed Temperature Sensing (DTS) System
DTS-BLY-5S(ADV-10km)
10 km Distributed Temperature Sensing (DTS) System
Measures continuous temperature profiles and abnormal-temperature locations along the fiber. Select range, fiber type, channels and sensing cable for the specified model.
Typical applications
Coal-mine surface facilities, power tunnels, metro electrical safety, nuclear power plants, renewable energy facilities, transportation tunnels, fire protection and fire detection, etc.
Spatial resolution, sampling interval and location accuracy are distinct quantities. Temperature accuracy depends on fiber length, acquisition time, temperature range and cable configuration; optimum values are not necessarily simultaneous.
Spatial resolution uses the 10%–90% step-response criterion and the ± spatial-extent notation used in this datasheet. Location accuracy is specified separately. Compare specifications using the same definitions and test conditions.
