D-LX 110 Compact Flame Monitor

Self-monitoring and fail-safe compact flame monitor for the monitoring of gas, oil and coal flames with integrated UV, VIS or IR flame sensor, primarily in single burner view applications.

Description

Self-monitoring and fail-safe compact flame monitor for the monitoring of gas, oil and coal flames with integrated UV, VIS or IR flame sensor, primarily in single burner view applications.


Overview

  • For ambient temperatures from -40°C up to +75/70°C, certified and without need for accessories to isolate, heat or cool.
  • Highest safety combined with highest availability
  • Ideal support for Functional Safety within safety chains up to SIL3
  • Flame relay output as changeover relay (SPDT, 1 x NO, 1 x NC)
  • All variants of the D-LX 110 also available for combination with fibre optic systems (see D-LX 710)
  • Easy exchange of consumables
  • Local display of settings and operational status for the whole ambient temperature range, visible for all versions at a single glance

Why use this product?

  • Easy adjustment
    The easy access to the available adjustments shortens time for commissioning
  • Versatile detection
    The choice of available detectors allows for the monitoring of flames of all fuels within the same device family
  • Versatile for the most variable application conditions
    The same device technology can be used without change for the most different geographical regions and based on varying systems of standards
  • Flexible for changed requirements
    If the requirements of the plant change (ex, zones, need for fibre optic systems) it usually is possible to adapt via a replacement within the same device family
  • Flexible operation support
    The possibility to adapt device settings also outside the factory enables fast local replacements with smaller stocks of replacement devices
