Det-Tronics MW225269-06 Sensor Assembly

Product Dimensions：

The Det-Tronics MW225269-06 is a high-performance UV/IR (Ultraviolet/Infrared) Flame Detector Sensor Module, typically used as a core component within the X5200 series or associated explosion-proof flame detection systems. It is engineered to detect hydrocarbon fires with extreme reliability while maintaining high immunity to false alarms.

Product Detailed Description

The MW225269-06 is an integrated sensor assembly that combines an ultraviolet sensor and an infrared sensor. By monitoring both the UV and IR spectral bands of a flame simultaneously, the device confirms a fire only when both sensors detect the specific radiant energy of a combustion event. This “dual-technology” approach prevents triggers from non-fire sources like lightning, arc welding, or hot machinery.

Technical Parameters

Product Advantages

• Superior False Alarm Rejection: By requiring “coincident” signals from both UV and IR sensors, it ignores common interference like sunlight reflected off water or artificial lighting.
• High Sensitivity: Capable of detecting a standard 1-square-foot (0.1 m^2) gasoline fire at distances up to 60 feet (approx. 18 meters).
• Automatic Optical Integrity (oi®): Features a self-test function that periodically checks the optical surfaces and internal circuitry to ensure the detector is functional without manual testing.
• Corrosion Resistance: The heavy-duty stainless steel housing makes it suitable for offshore and highly corrosive industrial environments.

Important Considerations (Precautions)

• Optical Path: The sensor’s “cone of vision” must remain unobstructed. Even a thin film of oil or heavy dust on the lens can reduce sensitivity; regular cleaning with approved wipes is required.
• Mounting Orientation: The detector should be angled downward to prevent water or debris from pooling on the lens.
• Welding Interference: While highly immune, intense arc welding in the direct line of sight should be avoided or the detector temporarily bypassed during maintenance.
• Field Wiring: Ensure all conduit entries are sealed with appropriate “stopping plugs” and “pour-fittings” to maintain the explosion-proof integrity of the assembly.

Product Applications

The MW225269-06 is found in high-risk industrial environments containing hydrocarbons:

• Oil & Gas: Offshore drilling platforms, FPSOs, refineries, and pipeline pumping stations.
• Chemical Processing: Ethylene plants, hydrogen storage, and solvent tank farms.
• Aviation: Aircraft hangars and fuel loading docks.
• Power Generation: Gas turbine enclosures and transformer vaults.
