Question

13.fiber - optic cables should be used to perform detection operations under which of the following conditions?
a. the sensing space is confined
b. the environment is hostile

Explanation:

Fiber - optic cables are suitable for hostile environments. In hostile environments (such as areas with high electromagnetic interference, corrosive substances, or extreme temperatures), traditional electrical - based detection cables may be damaged or their performance may be severely affected. Fiber - optic cables, which transmit light signals, are not affected by electromagnetic interference, have good chemical corrosion resistance (depending on the coating material), and can operate in a wide range of temperatures.

For a confined sensing space, while fiber - optic cables can be used, it is not the most characteristic condition for their use. There are other types of sensors (such as some miniaturized electrical sensors) that can also be used in confined spaces.

Answer:

b. The environment is hostile
