Honeywell's U2S Series is an all-in-one integrated signal processor and viewing head system for single or multi-burner, multi-fuel and difficult flame detection applications.
With up to three flame sensors and a signal processor in a single unit, U2 eliminates the need for a separate processor, saving on cabinets and wiring.
