Fireye 4-290-1 Tube 328140-751 Supporting a broad monitored currentThe Fireye 4 290 1 replacement UV tube is a critical component for maintaining reliable flame supervision in industrial burner systems. Designed for use with Fireye UV1A, UV2, and UV8A flame scanners, this ultraviolet sensing tube detects the UV radiation emitted by fossil fuel flames while ignoring infrared signals from hot refractory. As a non self checking UV sensor, it is engineered for intermittent operation where the burner cycles at least once
