The LG1093AA24 maintains stable loop continuity under high‑temperature conditions, with channel‑to‑channel isolation preventing interference when multiple sensors share a common panel interface. The optical window’s pressure rating supports continuous operation in elevated thermal zones, while the shielded cable minimizes noise ingress along long conduit runs.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the LG1093AA24 support hot‑swap replacement in a live control panel? A: The sensor can be replaced with power applied, but loop integrity must be maintained and the control panel must be in a safe state before disconnecting the cable.\u003c\/p\u003e\n\u003cp\u003eQ: What considerations apply to backplane or controller loading when adding multiple LG1093 sensors? A: Each sensor contributes a standard 4-20 mA channel load; ensure the panel’s analog input card supports the cumulative loop current and isolation requirements.\u003c\/p\u003e\n\u003cp\u003eQ: Are there firmware or configuration dependencies when integrating this sensor into Honeywell burner management systems? A: No firmware resides in the sensor itself; compatibility depends on the receiving controller’s analog input scaling and flame detection logic configuration.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaintain proper engagement of the 3\/4 inch internal NPT threads to ensure mechanical stability and prevent leakage around the optical window.\u003c\/li\u003e\n\u003cli\u003eRoute the Teflon shielded cable through the one inch external conduit thread, ensuring the shield is grounded at the control panel end only to avoid ground loops.\u003c\/li\u003e\n\u003cli\u003eAvoid sharp bends in the cable, especially near high‑temperature zones, to preserve insulation integrity.\u003c\/li\u003e\n\u003cli\u003eVerify that the flame sensor’s optical window remains unobstructed and free of soot accumulation; periodic cleaning may be required depending on burner conditions.\u003c\/li\u003e\n\u003cli\u003eEnsure cable length selection (AAx4, AAx5, AAx6) matches the physical distance to the control panel to avoid unnecessary loop resistance.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":48235490181310,"sku":"LG1093AA24","price":560.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-07-02_09-53-17_81169903-04ef-43dc-863b-19f93faa81d2.png?v=1784001184","url":"https:\/\/www.autooiltech.com\/ar\/products\/lg1093aa24-honeywell-lg1093-flame-sensor","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
