Durag D-LL 7XX Fibre Optic SystemFire Water Monitor

The installation of fibre optic systems is recommended if it is not possible to place the flame monitor at an optimal position in order to guarantee best and permanent flame monitoring. A fibre optic system is also useful if the conditions of the environment are harsh to electronic devices.

The fibre optic systems D-LL 701 and D-LL 702 have to be used in combination with the flame sensor D-LE 701. Fibre optic systems D-LL 703 and D-LL 704 are suitable for devices of type D-LE 703D-LX 710 and D-LX 721.
Overview

Possible applications are:

  • Flame monitoring of tilting burners
    Flexible fibre optic systems allow tilting of the viewing direction together with the burner.
  • Flame monitoring without direct view
    If there is no option to get a direct view of the flame from the installation position the line of sight can be bypassed around disturbing objects by using a flexible fibre optic system.
  • Flame monitoring for limited fields of view
    On long, narrow burners the opening at the sighting tube often limits the viewing angle. Normally this does not constrain the recognition of a flame. But especially if there are several burners facing each other the discrimination of the flames can be difficult. Installing a flexible fibre optic system at each single burner increases the viewing angle for the dedicated burner and improves the selective flame monitoring.
  • Flame monitoring at high ambient temperatures
    Recommended if high temperatures exist at the installation position.
    If the ambient temperatures at the installation position are higher than specified for the flame monitor the usage of a fibre optic system allows the installation of the flame monitor in a different position with lower temperatures.
