UV90L Series Scanner

The UV90L Series Scanner is designed for front and lateral (90°) mounting which, in some applications allow the scanners to obtain a clearer view of the flame.

 

The UV scanner is ideally suited for gaseous fuels (natural gas & propane). However, it can be used in detecting flames from standard fuel gases, some waste gases and light oil fuels such as No. 2 oil. Flames from heavier oils can be detected with UV scanners but the unburned fuel shroud and/or atomization shroud can block the passage of the UV from the flame zone to the UV tube, causing nuisance burner/boiler trips. Infrared detection is recommended for fuel oil heavier than No. 2, and some installations where waste gases are burned together with natural gas as the main flame.

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 comes 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 applications allow the scanners to obtain a clearer view of the flame. The UV90L, with its exclusive snugfit mounting block, eliminates the need for a threaded sight pipe. The UV5-1 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 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.
