-

There is only one input and one output line.

-

There is no electrical wiring, therefore, no explosion safety measures are required.

-

The operation of all sensors is continuously monitored.

Intrinsic safety

:

Temperatures are measured by an optical fiber. Since there is no electrical wiring, no explosion safety measures are required.

Low cost

:

One cable (optical fiber) can measure the temperature at hundreds of points.

Easy installation

:

All sensors are connected serially so cable installation is very simple.

Loop configuration

:

The loop measurement configuration provides accurate temperature distribution data regardless of the number of connection points and fluctuating temperature conditions.
Even if the optical fiber breaks, the system automatically carries on measuring without being interrupted.
