UV1AL-6

The UV1AL, UV90L, UV1AL-CEX and UV5 scanners are used with the BurnerPRO, MBCE and NXF4000 systems. The UV1AL-3/6 scanners come with 3 ft. or 6 ft. cables rated for Tray Cable - Exposed Run (TC-ER) and complies with the crush and impact requirements of the standard for metal clad cable, UL 1569. The UV1AL-3/6 is fitted with a 1/2” NPT threaded coupling. The UV90L-1/2 provides field wireable terminal block. The UV5-1 and UV5-2 come with a 6.5ft UL rated cable for installation. The UV1AL-CEX is a UV1AL mounted in a ATEX compliant housing for environments requiring the rating of Exd IIC T6 ATEX hazardous location. The UV90L Series Scanners are designed for front and lateral (90°) mounting which, in some appli cations allow the scanners to obtain a clearer view of the flame. The UV90L, with its exclusive snug fit mounting block, eliminates the need for a threaded sight pipe. The UV5 scanner also supports front and lateral viewing, but it’s highly recommended for lateral viewing to maximize the UV tube’s sensitivity. The UV5-1 is shipped with a mounting flange and a detachable cable. The UV5-2 is shipped with a mounting flange and integrated cable. The UV tube is made of quartz and is filled with a gas that ionizes when struck by UV radiation from the flame. In the absence of UV radiation, the gas acts as an insulator between two electrodes which are mounted inside the tube. These electrodes are energized continuously by a high voltage. During combustion, UV radiation ionizes the gas, causing current pulses to flow between the electrodes. These current pulses result in a flame signal which is transmitted to the amplifier in the control, where it is processed to energize or hold in the flame relay.
