DTS-BLY-5S(LDV-30km) · Multimode 30 km DTS
30 km multimode sensing; a 40 km fiber connection depends on the configuration.
DTS-BLY-5S(LDV-30km) Long-Range 30 km Distributed Temperature Sensing (DTS) System
DTS-BLY-5S(LDV-30km)
Long-Range 30 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
Long-distance power tunnels and utility cable galleries; district heating pipelines laid in shared corridors; submarine cables
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.
The nominal measuring range is 30 km. A 40 km fiber requires the applicable optional/custom configuration; far-end accuracy and acquisition time are project-specific.
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.
