Product Description

DTS (Distributed TemperATure Sensor) distributed multimode optical fiber temperature sensor can detect the temperature distribution of an optical fiber which is thousands of meters to dozens of kilometers long. The space sampling interval is only 1 m, and the detection period can reach second level. The fiber itself is made of quartz and has excellent electromagnetic inertia.
Cable and cable connector temperature monitoring; real-time temperature monitoring and abnormal alarm dynamic ampacity monitoring of high-voltage cables and their connectors through a distributed optical fiber temperature measurement system; calculate the core temperature of the cable through the mathematical model of dynamic ampacity, and further calculate the dynamic load Flow rate and various operating states;

Product features:
1.Fully distributed: DTS (Distributed Temperature Sensor) can completely detect the distribution temperature along the entire fiber in a few seconds.
2.Long-range monitoring: Skyray SRDTS-MK's single mode fiber can monitor the range of 25km.
3.Anti-electromagnetic interference: The temperature measuring fiber is composed of quartz, it can insulate the electricity and will not emit electric magnetic waves that especially suitable for various complex and strong electricity environment.
4.Intrinsic safety: The temperature sensing element is temperature measuring fiber. The average power of the optical signal transmitted internally is microwatt. The intrinsic safety can meet the highest requirements of petroleum and petrochemical industry.
5.Accurate locating : The Positioning accuracy can reach ±1m.
6.Quick response : The response time of single channel is only 2s.
