Distributed Fiber Optic Temperature Measurement System Temperature Sensing Fiber Optic Host Parameters

ʻIke wela optic, Pūnaehana nānā naʻauao, Hāʻawi ʻia ka mea hana fiber optic ma Kina

The distributed fiber optic temperature measurement system can provide real-time information on the surface temperature, core temperature, and joint temperature of the tested cable throughout the entire process, and has advantages such as anti-interference, intrinsic safety, long measurement distance, pololei kiʻekiʻe, and precise positioning. It is the best means of online status monitoring of power cables. FJINNO provides fiber optic temperature measurement hosts that comply with bidding standards and are reasonably priced.

Introduction to the functions of distributed fiber optic temperature sensing host

1) Real time data collection and display;

2) Realize distributed and real-time monitoring of cable temperature on the bridge, early fire alarm, and support monitoring of cable current carrying capacity;

3) The temperature monitoring interface can display the temperature curve inside the bridge in real time;

4) Multi zone configuration function: Set up zoning for fiber optic monitoring range according to on-site requirements;

5) Fiber breakage alarm function: When the temperature sensing optical cable is damaged, the detector can immediately locate the damaged point, and the optical cable before the damaged point can still maintain normal working condition;

6) When an alarm signal appears, it can switch to the alarm screen, displaying a schematic diagram and electronic map of the area where the alarm signal is located, indicating the alarm type (temperature abnormal alarm, fiber breakage alarm), and displaying the highest temperature or other related alarm indicators in the abnormal area;

7) Historical data display, storage, and viewing: At least six months of raw temperature data and one year of alarm data can be saved, and the corresponding historical temperature curve can be viewed by selecting the date and time;

8) Characteristic curve display;

9) Remote monitoring, diagnosis, and maintenance functions;

10) View the fiber optic cable loss curve for detection;

11) The alarm status of distributed fiber optic linear temperature detectors can be connected to the fire alarm controller through passive dry contacts.
