Product Details

The Fireye UV7SC is a high-performance self-check ultraviolet flame scanner designed for continuous flame monitoring on gas and light oil burners. This UV scanner uses a built-in mechanical shutter to run an automatic self-test every 10 seconds to confirm sensor integrity and prevent false flame signals. As a reliable flame sensor, it features a fused silica quartz lens and machined aluminum housing, suitable for demanding industrial combustion environments. This self-check detector works with Fireye MB series burner controls and MBPF flame sensing modules and requires the matching cable assembly 59-504-010 for connection. This Fireye UV7SC scanner is stocked as genuine replacement spare part for boiler and industrial burner flame supervision.

Supported Functions

This self-check UV flame detector captures ultraviolet radiation emitted by combustion flame and transmits a modulated flame signal to the matched flame safeguard control. If the flame disappears, it stops sending flame signal and triggers safety lockout and fuel shutoff. Every 10 seconds the internal shutter closes for an integrity test; if the scanner fails the self-check, it interrupts the output to force system shutdown.

Core Functions

The quartz UV tube ionizes under flame UV radiation to generate pulse flame signals. The periodic shutter self-test eliminates the risk of scanner runaway failure. Its robust metal construction resists heat and dust, and it can be replaced without rewiring the existing harness. It serves as a direct drop-in replacement for existing UV7SC installations.
