Product Details

The Fireye SB49600-90 is a right-angle 90‑degree ultraviolet flame scanner for the Fireye Bi‑Flame dual burner monitor and SB Series flame safeguard systems. This Bi-Flame 90-degree UV scanner captures ultraviolet radiation emitted by gas and light oil flames and transmits analog flame signals back to the host control for continuous supervision. As a reliable non self-check flame probe, it features a compact angled head to fit tight sight ports where straight scanners cannot be mounted conveniently. This 1/2 NPT ultraviolet sensor is widely installed on boilers, furnaces and process heaters and stocked as genuine replacement spare part for Fireye combustion safety systems.

Product type: Original Fireye flame sensing assembly

Supported Functions

This scanner continuously picks up UV radiation generated by combustion flame. When a stable flame signal is received, the burner control permits ongoing firing. If flame disappears, the controller triggers safety lockout and cuts fuel supply. Since it is non self-checking, it requires regular burner cycling to validate proper scanner function and avoid undetected sensor failure.

Core Functions

The 90‑degree angled housing simplifies installation in cramped burner enclosures and offset sight ports. The standard 1/2" NPT thread works with common flame sight fittings. It delivers consistent flame signal for routine burner supervision and serves as direct drop‑in substitution for existing SB49600-90 scanners.
