LG1093AA46 Honeywell UV Flame Detector Geiger-Mueller Sensor - New

Global PLC Spare HUB's Insight

• The LG1093AA46 stands as a high-tier UV detection solution, specifically engineered for the extreme thermal environments of industrial combustion.
• Utilizing a Geiger Mueller-type phototube, the LG1093AA46 filters out solar radiation to focus exclusively on the 180-260 nm ultraviolet spectrum.
• This sensor acts as a direct cross-reference for the GE 261A1812P15, making it an essential spare for gas turbine and heavy-duty boiler maintenance.
  

Core Technical Parameters

• Manufacturer: Honeywell
• Model Number: LG1093AA46
• Detection Type: Ultraviolet (UV) Radiation Sensor
• Spectral Sensitivity: 180 to 260 nm (Optimized for flame detection).
• Response Speed: Detects flames in 0.1 seconds and recognizes flame loss within 0.2 seconds.
• Temperature Tolerance: Designed for extreme operations from -40°C to 176°C.
• Pressure Rating: The viewing window sustains industrial process pressures up to 10 bar (150 psi).
• Wiring: Features a 61-foot (12.8 meter) Teflon shielded cable for high-temperature signal integrity.
• Mounting: 3/4 inch internal NPT threading allows for standard industrial porting.
• Voltage Range: Compatible with 28 Vdc (20-35 Vdc) or 115 Vac power infrastructures.

Diagnostic Capabilities & System Integration

• Remote Monitoring: Supports reliable signal transmission up to 330 meters (1000 feet) from the sensor to the amplifier.
• Output Flexibility: Interfaces seamlessly with EG1033AA (Transistor) or EG1033AB/AC (Relay SPDT) amplifiers.
• Signal Integrity: The integrated Teflon shielded cable minimizes electromagnetic interference (EMI) during operation.
• Direct Replacement: Fully validated for systems requiring the GE 261A1812P15 specification for gas turbines.

Application Scenarios and Equipment Fit

• Gas Turbines: Primary flame monitoring for power generation turbines and aerospace propulsion test cells.
• Industrial Boilers: High-temperature burner management in petrochemical, textile, and chemical processing plants.
• Refineries: Real-time monitoring of flare stacks and heater treaters where rapid flame loss detection is critical.
• Extreme Heat Zones: Specialized for applications where ambient heat reaches up to 176°C, exceeding standard sensor limits.

Strategic FAQ & Purchasing Guide

• Does the LG1093AA46 detect visible light or "background" furnace heat?
• The Geiger-Mueller tube is blind to visible light and IR, preventing false trips from hot refractory walls or sunlight.
• Selection Tip: When should I choose the LG1093AA46 over an infrared (IR) sensor?
• Select this UV sensor for cleaner-burning fuels like natural gas or hydrogen where IR signatures are often too weak.
• What is the benefit of the 61-foot Teflon shielded cable?
• The shielding prevents signal loss over long distances, while the Teflon jacket resists melting in high-heat zones near the burner.
• How do I verify if the viewing window needs maintenance?
• Check the signal voltage at the amplifier; a significant drop typically indicates soot or oil buildup on the 10-bar rated window.
• Experience Note: Is it possible to test the LG1093AA46 without a live flame?
• Technicians use a handheld UV test lamp focused on the 180-260nm range to verify the 0.1s response during routine commissioning.
