13. 28.02.2012 13 AP Sensing Confidential A fiber-optic linear temperature sensor can help to detect a potential fire in its early development phase Real time, continuous temperature monitoring of potential fire sources Complete local coverage of long structures (like tunnels) or large areas (like big buildings) without “blind spots” Pin-point alarm with exact temperature and location information enables quick intervention before the outbreak of a potential fire Fire Prevention

14. 28.02.2012 14 AP Sensing Confidential Example 1: Coal Conveyor Belts in Power Plants Real time, continuous temperature monitoring of potentially hot running rollers and smoldering fires Complete local coverage of long conveyor belts or a chain of multiple conveyor belts without “blind spots” Early alarming with exact location information enables an early exchange of hot rollers or the extinction of smouldering fires caused e.g. by self-ignition of lignite dust Fire Prevention – Coal Conveyor Belts

15. 28.02.2012 15 AP Sensing Confidential Example 2: Cable Trays, Cable Tunnels, Power Cables... Real time, continuous temperature monitoring of cable trays, cable tunnels and power cables heating up under high current load Complete local coverage of long cable trays or cable tunnels without “blind spots” Early alarming with exact location information enabling the decrease of electrical current, the exchange of bad joint and splices, etc. Local coverage can be increased by meandering the sensor cable The temperature difference and the temperature delay between conductor and outside of the cable has to be considered Fire Prevention – Cable Trays and Power Cables

16. 28.02.2012 16 AP Sensing Confidential Fire Prevention – Pipe and Tube Leakage Example 3: Leakage of Inflammable Liquids or Gases from Pipes and Tubes Real time, continuous temperature monitoring of potentially leaking tubes and pipes, e.g. hydraulic oil Complete local coverage of long pipes and tubes without “blind spots” Early alarming with exact location information enables an early sealing of the leak and removal of a potential fire load
