A sensing cable optimized for corrosive chemical liquids detection


Sensing cable optimized for corrosive chemical liquids detection

Specially designed for corrosive chemical liquids, the FG-AC sensing cable detects and precisely locates acid, corrosive chemicals as well as water leaks at any point along its length. An extensive number of acids can be detected (page 2). The cable is made of a corrosion-resistant fluoropolymer that can be re-installed after cleaning.

Addressable/digital sensing technology

Connected to any TTK digital leak monitoring panel (FG-NET, FG-BBOX, FG- SYS), the FG-AC sensing cables respond intelligently in the event of leaks of conductive liquids.

Each FG-AC acid sensing cable contains an embedded microprocessor, allowing a permanent monitoring of the cable status, using the same technology as the TTK water sensing cable. Real-time communication to the TTK panel is provided continuously. Every individual length cable of 3, 7 or 15 m is addressable, autonomous and independent, allowing simultaneous leaks detection within one detection line.

Each cable has a high visibility LED indicator to provide quick identification of the cable status allowing effortless inspection.

  • Green LED: normal status, no alarm raised;
  • Red LED: leak detection on the cable;
  • LED off: cable break on this or any upstream cable.


Easy extension of the system

Every individual standard length sensing cable can be interconnected (in both series and parallel mode) to provide an expandable network of leak detection.

Direct continuous and digital communication between the monitoring panel and each acid sensing cable (unlike zone monitoring panels in traditional analogue leak detection systems) makes the extension of the system easy.


Wide range of applications

The FG-AC sensing cables are small in diameter, light and flexible, allowing easy installation. The typical applications are laboratories, fab plants and cleanrooms among others. TTK acid sensing cables provide permanent protection to limit the financial consequences of an undetected chemical leak (Read the case study).


Proven strong resistance to fire and to abrasion

FG-AC fire resistance

The FG-AC acids sensing cable has successfully passed the most stringent test for plenum cables, NFPA 262 / UL 910, “Standard Method of Test for Flame Travel and Smoke of Wires and Cables for Use in Air-Handling Spaces” (also known as “Steiner Tunnel” Test) at the Fire Testing Laboratory of Intertek, USA in 2007.
