Product Announcement from Alstom


Diagnostic Flame Indicator-Image

The LIMELIGHT™ Diagnostic Flame Indicator (DFI) is a state-of-the-art diagnostic flame-proving device designed for reliable and consistent operation with an ignitor. The DFI is an upgrade replacement for Limelite 2000 and Ionic Flame Monitoring (IFM) flame proving devices.

This product can be used with oil or gas ignitors in Utility, Pulp & Paper and Industrial applications.

A variety of LIMELIGHT™ DFI models are available to meet your existing mounting arrangement and the level of diagnostics desired.

Technical Highlights

The LIMELIGHT™ DFI uses advanced digital signal processor (DSP) technology. The DSP chip offers industry-leading performance of 40 million instructions per second (MIPS) enabling real time Fast Fourier Transform analysis.

The DFI records ignitor operational history so you can determine when maintenance is required at a glance. An optional control cabinet window kit is available to take advantage of this feature.

The LIMELIGHT™ is designed for easy firmware upgrades as new software functions become available.

The DFI communicates to your host computer or burner management system through industry standard interfaces. Communication among LIMELIGHT™ DFI modules is accomplished using CANbus technology. RS232 and 4 to 20 mA communication outputs are available.

The LIMELIGHT™ DFI is delivered preprogrammed, ready for a simple installation. On-site tuning will allow you to customize the DFI for optimum performance.

The DFI is designed for industrial service with a temperature rating of 70ºC / 158ºF and front-end electronics with greater immunity to noise and grounding problems.

Operating voltage on the flame rod is 40 volts DC, allowing for optimum signal to noise ratios while maintaining low rod voltage for personnel protection.
