Honeywell LG1093AA24 LG1093 Flame Sensor

Description

Industrial combustion systems require highly reliable monitoring, and the Honeywell LG1093AA24 meets this demand as a rugged gas turbine flame sensor. Designed to detect ultraviolet radiation emitted by combustion flames, this industrial sensor provides rapid, precise signal transmission to flame safeguard controls. Built to withstand extreme mechanical and thermal stress, it features a robust housing and high-pressure window, making it suitable for hazardous and harsh process environments.

The sensor is pre-configured with a robust electrical interface featuring a Teflon-shielded cable to ensure signal integrity against electromagnetic interference (EMI). Its heavy-duty construction facilitates long-term deployment in utility boilers and power generation applications where continuous, uninterrupted flame supervision is critical.

Features

• Highly sensitive ultraviolet (UV) tube sensing technology for accurate flame verification.
• Durable mechanical design suitable for extreme temperature and pressure environments.
• Integrated Teflon-shielded connection cable prevents signal degradation from heat and electrical noise.
• NPT standard threading for secure mounting onto process burner assemblies.
• Conduit connection interface simplifies integration into rigid or flexible electrical conduit systems.

Applications

• Industrial gas turbine flame supervision
• High-capacity utility boiler systems
• Petrochemical and refinery process burners
• District heating plant combustion monitoring

Installation Guidelines

• Mount the sensor so that its line of sight is directed at the primary combustion zone, avoiding obstruction from burner components.
• Apply high-temperature thread sealant to the 3/4 inch NPT interface to prevent process gas leakage.
• Route the Teflon-shielded cable away from high-voltage igniter leads to prevent electromagnetic interference.
• Keep the viewing window clean and free of soot or oil deposits by periodically executing maintenance cycles.
