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.

FEATURES

• 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”).

BENEFITS

• 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
