The DTS system using the optical fiber sensor cable is intrinsically safe to use in explosive
gas atmospheres because no electrical voltage is applied to the cable.
One of the examples of making the most of this technology is in leakage detection systems for LNG tanks.
The DTS system is similarly applicable to fire detection systems for oil storage tanks.
We provide the optical fiber sensor cable applicable to low temperature use as special specifications.
Optical fiber sensor cable installed around the circumference of the bottom of LNG tanks detect the temperature
drop caused by leakage, and triggers an alarm.
Temperature monitoring of the foundation
The temperature distribution of the foundation can be monitored by embedding the optical fiber sensor
cable in the foundation.
Such temperature monitoring data is useful for preventing ground freezing and also for controlling heaters.
