Description
The new Durag D-LX 100 compact flame monitor is the first system of its kind to meet current American and European flame monitoring standards.
The D-LX 100 was designed for continuous, intermittent and 72-hour operation. The flame monitor’s compact design integrates the flame scanner and amplifier into one compact housing. This greatly reduces overall cost and simplifies installation
I. General Introduction
The D-LX 100 Compact Flame Monitor has been developed to monitor flames in single burner systems. The integrated relay output may be used to interface with the fuel control valve. Applications for the D-LX 100 range from small heating plants to process combustion systems.
These flame monitors have a spectral sensivity of either 190 to 520 nm. All blue-burning flames may be monitored by these flame monitors. Flames whose UV-radiation is absorbed by dust, water vapor or other materials, and which cannot normally be monitored by UVtubes, may be monitored by these highly sensitive semiconductor UVphotoelements. These flame monitors have also proven themselves in monitoring gas and oil combustion systems employing NOx reduction techniques such as flue gas recirculation.
