产品型号 / Model: DTS-BLY-5S (HL-10km)

用于沿光纤连续获取温度分布与异常位置。测量量程、光纤类型、通道及现场光缆按对应型号选配。
Measures continuous temperature profiles and abnormal-temperature locations along the fiber. Select range, fiber type, channels and sensing cable for the specified model.
典型应用 Typical applications
宽温域应用:液氮系统、高温炉、卫星发射设施及核电高温环境
Wide-temperature-range applications: liquid nitrogen systems, high-temperature furnaces, satellite launch facilities, and high-temperature nuclear power environments.
空间分辨率、采样间隔与定位精度为不同指标。温度精度随光纤长度、采集时间、温区及光缆配置变化;各项最优指标不代表在同一配置下同时达到。
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.
空间分辨率按10%–90%阶跃响应口径列示,采用“±”空间范围记法;定位精度另列。规格比较须采用相同定义与测试条件。
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.
