The 65UV5 scanner is available with a one-second or four-second flame failure response time (FFRT) depending on the model selected. The “E” versions are one-second FFRT, the non ”E” versions are four seconds FFRT. The Fireye 65UV5-1004QD and 1004EQD flame scanners provide an analog 4 to 20 mA output referenced to flame signal strength.

Fireye 65UV5 self-checking scanners are used to detect ultraviolet emissions from fossil fuel flames such as natural gas, coke oven gas, propane, methane, butane, kerosene, light petroleum distillate sand diesel fuels.
