Each FG-HC2 sensing cable comes in a standard and prefinished length of 2 m. FG-HC2 is light, flexible and protected by a tinned-copper braiding. The FG-HC2 cable is made with two helically extruded copper conductors twined around a central core.

 

When a leak appears on the FG-HC2 sensing cable, the nonconductive liquid seeps under the mass braiding and causes variations in the electrical values that typify the detector cable. Rapid detection is triggered electrically.

 

The FG-HC2 will not detect a water leak or any residual part of non-conductive liquids, such as hydrocarbons and solvents. Nevertheless, the installation must be done in a safe and dry location.

 

After a leak detection, the sensing cable FG-HC2 must be replaced; with its male and female plugs, it is easy to remove. The electronic module will stay in good condition in its original location.
A termination plug ends the circuit; a test termination plug is included with the hydrocarbon detection set, in order to simulate a leak once the new sensing cable
has been installed. A set of neutral cables and diversion boxes ensures the modular aspect of the system: 10 lengths of FG-HC2 sensing cables can be
connected to the same circuit with an FG-SYS digital unit.
