Description: Flame monitors and flame sensors are offered. Flame detection is important in combustion systems, especially if the system has automatic control. Three basic techniques well accepted all over for flame sensing are 1) using Diligent PR-EYE Photo Resistor flame sensor with Diligent Flameye PR flame monitor. 2) Using Diligent PV-EYE PhotoVoltaic Flame sensor with Diligent UV-EYE UltraViolet flames sensor with Diligent Flameye UV flame monitor. The first technique is the most cost effective and reliable choice for sensing bright luminous flame such as in furnace heavy oil burners. The second technique is also equally good for such flame but is expensive. Both however, cannot sense near-invisible/ blue flame such as in gas or light oil burner. The third technique though quite expensive, is the only proven and reliable one for sensing gas flame and this technique can also sense bright flames. It is, therefore, very useful in gas-cum-oil burner. Diligent flame sensors are housed in strong case and have shielded cable for interconnection. Some of these are also available in Front Viewing and Side Viewing Models (Designated by Suffix FV & SV). Diligent flame monitor provides one potentially free change-over contact output, status LED display and choice of operation logic, that is, Normal Logic designated by suffix-O (Flame ON-Relay ON) & Inverse Logic designated by suffix-I (Flame ON-Relay OFF). Standard optional features available are customer-specified number of output contacts, time-delayed response to flame-ON condition, time-delayed response to flame-OFF condition and choice of one of the standard control power supply.
