The Fireye UV1A12 is a miniature ultraviolet (UV) flame scanner designed for non-self-checking applications, suitable for monitoring combustion flames fueled by gases and No. 2 oil. It operates by detecting UV radiation emitted from the flame, with a quartz UV tube that ionizes upon exposure to UV light, generating current pulses between internal electrodes. These pulses are transmitted to the control system’s amplifier, which processes the signal to confirm flame presence. The UV1A12 features a non-replaceable UV tube and is engineered for continuous operation in industrial burner management systems.
