Performance Advantages of Ultraviolet Flame Detectors

I. Core Working Principle

Flame UV CharacteristicsWhen gas or oil burns, it emits ultraviolet radiation in the 185-260nm band, which is the "exclusive signal" for identifying flames.

Optical Signal ConversionThe probe is equipped with a high-sensitivity ultraviolet photoelectric tube imported from Japan. When the flame ultraviolet light illuminates the cathode, it excites photoelectrons, which, under the influence of a high-voltage electric field, trigger "avalanche discharge," forming a pulse electrical signal that is proportional to the intensity of the flame.

Interference-Resistant LogicThe probe only responds to the ultraviolet band of 185~260nm, while the ozone layer absorbs the ultraviolet light in this band from sunlight, thus avoiding interference from sunlight and lights, and reacting only to flame signals.

Core Structural Design

Probe structure designed around industrial scenariosExplosion-proof, temperature-resistant, anti-pollutionRequirement Design:

Functional ComponentsComposed of ultraviolet photoelectric tubes, high-voltage drive modules, and signal preprocessing circuits, it offers a response time of ≤0.2 seconds and can quickly output flame status signals.

Environmental CompatibilityEquipped with high-temperature-resistant quartz glass lenses; operating temperature range covers -20℃ to 80℃; G1 internal thread and M20*1.5 electrical interface for standardized installation compatibility.

III. Technological Advantages

Swift response, secure interconnection: The detection response is ≤0.2 seconds, allowing for rapid signal feedback during flame anomalies, triggering the shutdown of fuel valves to prevent risks.

Highly resistant to interference, stable and reliableNo response to sunlight and high furnace temperatures, suitable for complex operating conditions.

Low energy consumption and easy maintenanceCore components have long lifespans, easy installation and debugging, significantly reducing O&M costs.

The probe is widely used for flame monitoring in heating furnaces, hot air furnaces, and internal combustion torches, etc., to achieve ignition failure protection and accidental extinguishing protection. It forms a closed loop with the combustion control system, fortifying a safety barrier for industrial production.
