Product Details

The Fireye UV90L-1 is a non-self-checking ultraviolet flame scanner for Fireye burner management systems, compatible with BurnerPRO, MBCE and NXF4000 series flame safeguard controllers. This ultraviolet flame scanner captures ultraviolet radiation emitted by combustion flames and transmits valid flame presence signals to the main control unit to implement burner safety interlock protection. As a reliable burner flame detector, it supports both front viewing and 90-degree lateral viewing, equipped with a field-wireable terminal block and exclusive snug-fit mounting block without threaded sight pipe requirement. This Fireye UV sensor is stocked as original replacement spare part, widely used to replace failed flame probes on gas and light oil industrial burners.

Supported Functions

This ultraviolet flame scanner continuously senses UV signals generated during stable combustion. The burner flame detector converts optical flame signals into electrical feedback for the burner safeguard control. It sends flame-loss signals once the flame disappears to trigger burner shutdown sequence and cut fuel supply. This Fireye UV sensor supports long-term continuous monitoring and works reliably under normal industrial combustion operating conditions.

Core Functions

High-sensitivity UV tube identifies real flame UV radiation and suppresses most false triggers from hot refractory surfaces. The ultraviolet flame scanner provides flexible installation orientation for difficult sighting positions on boilers and furnaces. Its integrated mounting design simplifies field installation and alignment. Standard terminal definition supports direct substitution for a faulty UV90L-1 without complicated modification of existing burner wiring.
