System integration is achieved through high-speed discrete signal conditioning via the amplifier unit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannel-to-Channel Isolation\u003c\/strong\u003e: The sensor utilizes a Geiger Mueller-type phototube which provides inherent electrical isolation from the combustion environment. This ensures that high-voltage ignition transients or localized electromagnetic interference in the turbine casing do not propagate to the amplifier's input stage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCJC and Sensing\u003c\/strong\u003e: The sensor maintains high sensitivity to UV emissions while remaining solar blind and tolerant to infrared black body radiation. It supports cable distances of up to 330 m when paired with compatible amplifier modules.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: Is the LG1093AC05 compatible with DLE (Dry Low-NOx) turbine configurations?\u003c\/p\u003e\n\u003cp\u003eA: No. The standard LG1093 series may not perform as expected on GE\/NP DLE gas turbines. These specific applications require pre-selected sensors not supported by this model.\u003c\/p\u003e\n\u003cp\u003eQ: Does the sensor require a dedicated power supply?\u003c\/p\u003e\n\u003cp\u003eA: No. As a passive Geiger Mueller phototube, the sensor does not require a local supply voltage; the required excitation is provided by the connected EG1033 amplifier module.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical Mounting\u003c\/strong\u003e: Ensure the sensor is mounted to the turbine viewing port using the flange interface. Verify the viewing window pressure rating (6.3 psi) is sufficient for the application environment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring\u003c\/strong\u003e: Use the provided 2-conductor armored cable to connect the sensor to the amplifier module. Ensure the cable is secured and protected from mechanical abrasion and excessive heat near the turbine casing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding\u003c\/strong\u003e: Maintain a continuous ground path for the armored cable shield back to the control cabinet earth to prevent electrical noise coupling into the sensitive UV detection circuit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHazardous Area Compliance\u003c\/strong\u003e: When installing in areas with CE\/ATEX ratings (EEx d IIA T3), use only approved explosion-proof conduits and fittings. Do not modify the sensor housing or cable entry, as this voids the hazardous atmosphere certification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValidation\u003c\/strong\u003e: Verify correct signal polarity at the amplifier input. Confirm flame monitoring logic is functioning by observing the flame-on\/flame-off response times (0.1 s to 0.2 s) during cold-start testing.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":48177216651454,"sku":"LG1093AC05","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-07-20_09-51-20_361c7eda-fcbd-4b78-94aa-5c6cf1b20ae7.png?v=1784518626","url":"https:\/\/www.autooiltech.com\/products\/honeywell-lg1093ac05-flame-sensor","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
