Product Specifications

Technical details and manufacturing context for Flame Sensor/Scanner

Definition
A critical safety component within combustion systems that continuously monitors flame presence using optical, thermal, or electrical detection methods. It provides real-time feedback to the control system to maintain safe combustion operations, trigger shutdown sequences during flame failure, and prevent unburned fuel accumulation that could lead to explosions or equipment damage.
Working Principle
Operates by detecting specific characteristics of flame such as ultraviolet (UV) radiation, infrared (IR) radiation, or flame rectification current. UV sensors detect the ultraviolet light emitted by flames, IR sensors monitor infrared radiation patterns, while flame rod sensors use the electrical conductivity of ionized gases in the flame to create a small current. The detected signal is processed by the control system to determine flame status.
