Distributed optical fiber temperature sensor system
based on the principle of Raman scattering and optical
time domain reflection can get spatial temperature information.
It can realize the wide range, long distance real-time
temperature monitoring using the optical fiber cable
as its sensor. This set of system has incomparable merits,
such as the fire-proof, the explosion-proof, the corrosion
preventing, thermostable, the anti-electromagnetic radiation,
the broad survey scope, the high pointing accuracy and
easy to operate.
● The online
temperature monitoring and superheat alarm system of buried
cable ● Temperature monitoring and
superheat alarm system about power plant, transformer substation
as well as large-scale power transformer ● The fire preventing and
controlling and temperature alarm system on coal mine, transportation
domain ● Temperature detecting and
superheat alarm system on every kind of oil pipeline ● Big area, wide range temperature
survey and monitoring alarm system
● Optical fiber
cable not only is the sensor also is the communication
channel, also safety in nature
● Friendly user interface
● Many districts and alarming setup, many kinds of temperature
alarms
● Simple temperature fitting, system configuring and operating
● Flexible data , long-distance access
