TTK FG-OD Hydrocarbon Sense Cables

TTK 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 and re-usable after leak detection. Can be installed in a 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-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”).

Benefits

• 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.
