Fireye 95DSS2-1 – Enhanced InSight Flame Scanner (Dual Sensor UV & IR)
The Fireye 95DSS2-1 InSight Scanner is an advanced microprocessor-based flame scanner featuring dual ultraviolet (UV) and infrared (IR) sensors. Designed for multi-fuel and multi-burner applications, it provides accurate flame detection, self-diagnostics, and an internal flame relay, eliminating the need for a separate flame amplifier.
This enhanced InSight scanner replaces older Fireye 45FS1, 45UVFS1, and 45RM4 signature scanners, providing high reliability and advanced features for industrial burners.
