1. General Introduction
Durag D-LX 110 flame monitor investigates the intensity of the flame flickering or of the radiation in the short wavelength range. It distinguish the signal from the background radiation of the hot fixtures within the chamber. Monitor the flame the device evaluates electromagnetic radiation in the ultraviolet, visible or infrared region of the spectrum for its flame specific portions and analyses these in more detail. As a safety device the D-LX 110 is built fail safe and self-monitoring. Through its design as a compact flame monitor it possesses two direct relay outputs for the flame signal. As a modern flame monitor it allows for flexible adjustment to the local combustion conditions. It mainly come with typical features as below:
u Easy adjustment: The easy access to the available adjustments shortens time needed for commissioning
u Versatile detection: The choice of available detectors allows for the monitoring of flames of all fuels within the same device family
u 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
u Flexible for changed requirements: If the requirements of the plant change(Ex zones, need for fiber optic systems) it usually is possible to adapt via a replacement within the same device family
u Flexible operation support: The possibility to adapt device settings also outside the factory enables fast local replacements with smaller stocks of replacement devices
