Honeywell LG1093AC01
Product Name: Ultraviolet (UV) flame sensor, LG1093 series.
Product Introduction: The LG1093AC01 is a Honeywell UV flame sensor for continuous monitoring of industrial combustion processes. Like other members of the LG1093 family, it senses ultraviolet radiation from hydrocarbon flames and delivers a fast, reliable flame-proven signal to burner management or flame safeguard systems.
Detailed content
Technical Specifications:
- Detection band: approximately 180 to 260 nm (solar-blind UV)
- Supply voltage: DC or AC versions available
- Response time: sub-second class
- Ambient temperature range: approximately −40 °C to +85 °C
- Maximum cable distance between sensor and amplifier: up to several hundred metres depending on wiring
- Output: pulse or relay-compatible signal
Functional Features:
- High sensitivity and fast response for rapid flame-failure detection
- Strong immunity to ambient light, arc welding flashes and hot surfaces
- Robust construction resistant to heat, vibration and electrical noise
- Drop-in compatibility within the LG1093 family for like-for-like replacement
Application Scenarios: Gas turbines, industrial kilns and furnaces, steam and hot-water boilers, incinerators, and process heaters requiring flame supervision.
Installation Requirements: Mount so the optical window faces the primary flame zone. Route sensor cables away from high-voltage and ignition leads to prevent induced noise. Observe the maximum cable length specified in the installation sheet and use the recommended cable type.
Precautions: Verify the exact suffix and supply rating before purchase. Clean or replace the optical window on schedule and prove the flame failure path during commissioning. Refer to the official Honeywell documentation for final ratings and wiring details.
