Sense cables

Hydrocarbon Sense Cables


  • Intermediate Sensitivity
  • Fast Response with Light and Middle Distillates
  • Leak Location on Section Length
  • Re-usable and Pre-connected Cable
  • Suitable for Explosive Area Service
  • Insensitive to Water and Inorganic Pollutants

FG-OD: Addressable Oil Sense Cable

  • FG-OD is a digital sense cable for detection and location, along the entire length, of liquid hydrocarbons and liquid insoluble in water present on the cable.
  • It allows multiple leak detection and location thanks to independent digital addressing, enabled by an embedded microchip in each FG-OD sense cable.
  • Fast response.
  • Re-usable after leak detection.
  • Can be installed in humid environment, as it is insensitive to water and inorganic contamination.


  • Standard length (3 m, 7m, 12m and 20m) sensor sections or long line section allowing optimised system architecture.
  • Microprocessor embedded in each FG-OD sense cable allowing independent digital transmission to the alarm unit.
  • Standard length sense cable provided with built-in plug-socket connector.
  • Long line provided with built-in intermediate embedded connections (for each section), plus connector at extremities on demand. Structure of the sense cable comprising a silicon sensing wire, a continuity wire, a communication wire (proprietary bus) and the power supply wires.
  • Protective external PE braid built on the cable. Intrinsically safe – can be used in classified areas: Ex ia IIB T4 Ga (IECEx “Zone 0”).


  • Reliable detection:
    – Sensitive to liquid hydrocarbons.
    – Insensitive to water, inorganic pollutants and external loads (pressure).
  • Examples of detection time: Gasoline: 3-6 minutes (*), Diesel Oil: 25-35 minutes (*), Jet Fuels: 10-20 minutes (*).
  • Detects and locates hydrocarbon leaks on the section length.
  • Can be reused, allowing leak detection tests under real conditions.
  • The same unit FG-NET can be connected to FG-OD sense cables and mixed with water or acids / bases sense cables at the same time.
  • Easy to install and remove: standard FG-OD cables pre-connected with male / female connectors.


(*) : depending on liquid composition and leak conditions

Embedded microchip in each FG-OD sense cable allows multiple leak detection and location on one circuit:
