Physical mounting through a 3\/4 inch internal NPT connection interfaces directly with sight pipes to monitor combustion intensity. Electrical signals translate through a Teflon shielded cable to communicate flame state feedback directly to control panels.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eLG1093AA26\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e4.00 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard Optical Housing Assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-40 to +176 deg C (-40 to +350 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003ePassive Sensing Element\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor Type\u003c\/td\u003e\n\u003ctd\u003eOptical Flame Sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Interface\u003c\/td\u003e\n\u003ctd\u003e3\/4 inch internal NPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl Connection\u003c\/td\u003e\n\u003ctd\u003eTeflon shielded cable with 1 inch external conduit thread\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Rating\u003c\/td\u003e\n\u003ctd\u003e150 psig at 204 deg C (400 deg F) window rating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Length\u003c\/td\u003e\n\u003ctd\u003e61 ft (18.6 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eChannel-to-Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe LG1093AA26 sensor assembly incorporates signal isolation via a Teflon shielded cable harness to prevent signal degradation and cross-talk across adjacent sensor channels. Shielding suppresses electromagnetic interference from high-voltage ignition spark transformers and adjacent electrical drives. High dielectric isolation safeguards control panel inputs against field ground loops and common-mode transients occurring along the sight pipe housing.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the LG1093AA26 flame sensor be serviced or disconnected while the combustion chamber is pressurized?\u003c\/p\u003e\n\u003cp\u003eA: No. The viewing window maintains a 150 psig pressure rating at 204 deg C. The process line must be depressurized and isolated before removing the sensor from its 3\/4 inch NPT mounting thread.\u003c\/p\u003e\n\u003cp\u003eQ: How is signal shielding maintained along the 61 ft cable run to the control panel?\u003c\/p\u003e\n\u003cp\u003eA: The Teflon shielded cable uses an integrated shield conductor connected through a 1 inch external conduit thread to maintain low-impedance grounding and noise suppression.\u003c\/p\u003e\n\u003cp\u003eQ: What is the operating temperature threshold for the sensor electronics and housing?\u003c\/p\u003e\n\u003cp\u003eA: The sensor housing and internal optics are rated for continuous operational exposure between -40 and +176 deg C (-40 to +350 deg F).\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the 3\/4 inch internal NPT mounting threads and clean the sight pipe opening prior to installation.\u003c\/li\u003e\n\u003cli\u003eEngage the mounting thread with a minimum of 5 full turns of thread engagement, applying high-temperature thread sealant as required.\u003c\/li\u003e\n\u003cli\u003eRoute the Teflon shielded cable through a 1 inch conduit, maintaining separation from high-voltage ignition leads and AC power cables.\u003c\/li\u003e\n\u003cli\u003eVerify window glass seal integrity to prevent hot combustion gas bypass under process pressures up to 150 psig.\u003c\/li\u003e\n\u003cli\u003eConnect the cable shield drain wire directly to the control panel earth ground bus bar.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":53620481130805,"sku":"LG1093AA26","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/LG1093AA26.png?v=1789969367","url":"https:\/\/www.5gplc.com\/products\/honeywell-lg1093aa26-lg1093-flame-sensor","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
