DTS-BLY-5S (HL-10km) · Custom high / low temperature DTS
Custom temperature sensing for hot/cold processes with sensing cable rated for the required temperature band.
High-/Low-Temperature Distributed Fiber Optic DTS System
High-/Low-Temperature Distributed Fiber Optic DTS System
Model: DTS-BLY-5S (HL-10km)
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
Wide-temperature-range applications: liquid nitrogen systems, high-temperature furnaces, satellite launch facilities, and high-temperature nuclear power environments.
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.
