Description:


          DTS (Distributed Temperature Sensing System)  adopts the advanced feature that OTDR technology and RAMAN distributed light is sensitive to  temperature, which can detect the temperature changes at different locations along the optical fiber, to realize the real distribution  measurement. It has 4, 8, 16 channels system. 

          DTS not only can do fire alarm on time, but also can locate the fire area place. As one mature distribution measurement system , it has the advantages of Long measurement distance, High accurate, fast reaction speed, anti-electromagnetic interference , being suitable for the inflammable and explosive place.

DTS Application:

It can realistic the real time distribution temp measurement of the large space cable trench, joint or cable which put inside the pipe gallery. 

It is suitable for the inflammable and explosive place, strong electromagnetic interference and bad environment such as industrial sites. It is also widely used in high voltage cable on-line monitoring, power load flow analysis, traffic tunnel fire monitoring, oil and gas storage tank fire monitoring, fire monitoring on coal conveying belt, dam seepage monitoring and other fields. It provides a completed system solutions which has been applied in many power engineering project.

 

DTS Feature: 

1. High temperature sensitivity, short response time.

2. Long measurement distance.

3. Real time monitor, accurate positioning.

4. Distribute and Continuous measurement , real time detect the temp distribution inside the large space.

5. Laser signal detection, no power during the detection process, safe and anti explosive.

6. Strong anti-electromagnetic interference ability.
