UV Non Self-Checking Flame Scanner

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 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.
