OVERVIEW

D-LX 110/710

OPTICAL COMPACT FLAME MONITOR

Easy, versatile and flexible compact flame monitor with integrated UV, VIS or IR flame sensor for monitoring gas, oil and coal flames. Particularly for applications with single burner view.

 

DETAILS

  • Large temperature range: Deployable without change, certified and without the need for accessories for insulation, heating or cooling
  • Two-channel control unit module for highest safety simultaneously with high availability
  • Ideal support of Functional Safety within safety chains up to SIL 3
  • Two flame ON/OFF contacts for the flame signal (normally open and normally closed)
  • D-LX 110 and D-LX 710: Variants for direct view or for combination with fibre optic systems, also in hazardous areas
  • Easy replacement of consumable parts
  • Local display: Operational status and settings visible at a single glance, for complete temperature range and all variants
  • D-LX 710 for application with flexible fibre optic system D-LL 703 / rigid fibre optic system D-LL 704
  • Easy access to the available settings reduces the time required for commissioning 
  • Choice of the available detectors allows the monitoring of flames of all fuels within the same device family
  • The same device technology can be used for plants in the most varied regions and on the basis of a wide range of systems of standards
  • If the requirements for the plant change (Ex zones, need for fibre optic systems) exchange within the device family is usually possible
  • The ability to adjust the settings outside the factory allows prompt exchange with smaller local stocks of replacement devices are low
