Sense cables

Hydrocarbon Sense Cables


  • Low Sensitivity
  • Suitable for volatile liquids in confined environments
  • Suitable for weakly polluted environments
  • Leak Location on Section Length
  • Re-usable and Pre-connected Cable
  • Suitable for Explosive Area Service
  • Insensitive to Water and Inorganic Pollutants

FG-ODR: Low Sensitivity Addressable Oil Sense Cable

  • FG-ODR 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.
  • The FG-ODR cable is suitable for using with volatile liquids in confined environments and weakly polluted environments.
  • It allows multiple leak detection and location thanks to independent digital addressing, enabled by an embedded microchip in each FG-ODR sense cable.
  • 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-ODR 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 volatile liquid hydrocarbons.
    – Insensitive to water, inorganic pollutants and external loads (pressure).
  • Examples of detection time: Gasoline: 20-30 minutes (*), Jet Fuels: 2-4 hours (*), Diesel Oil: 3-6 hours (*).
  • 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-ODR sense cables and mixed with water or acids / bases sense cables at the same time.
  • Easy to install and remove: standard FG-ODR cables pre-connected with male / female connectors.

Note (*): depending on liquid composition and leak conditions

Embedded micro controller in each female connector of the FG-ODR sense cable allows detection and localization of multiple leaks on the same circuit
