The 4-20 mA HART loop protocol enables simultaneous analog process variable transmission and digital parameter configuration across control networks. Channel-to-channel isolation within the receiver circuitry prevents ground loops and common-mode voltage interference during prolonged outdoor exposures. Cold junction compensation (CJC) and internal temperature tracking algorithms maintain measurement linearity across extreme ambient thermal variations without zero drift.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the nominal response time for this infrared gas detector?\u003c\/p\u003e\n\u003cp\u003eA: The detector delivers a T90 response time of less than 4 seconds under standard hydrocarbon exposure conditions.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 4-20 mA output be configured for fault indication signaling?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the output can be scaled to drop below 3.5 mA or rise above 21 mA to indicate specific optical or hardware fault conditions.\u003c\/p\u003e\n\u003cp\u003eQ: What type of cable entry threads are available on the stainless steel housing?\u003c\/p\u003e\n\u003cp\u003eA: The housing accommodates either M20 or 3\/4-inch NPT threaded entries depending on the specific variant configuration.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMount the detector securely to a rigid structural support or dedicated mounting bracket using the 316 stainless steel housing to minimize mechanical vibration interference.\u003c\/li\u003e\n\u003cli\u003eEnsure the optical path between the transmitter and receiver windows remains completely unobstructed by structural elements or accumulated debris.\u003c\/li\u003e\n\u003cli\u003eRoute shielded twisted-pair instrumentation cables through approved conduit fittings, ensuring proper shield grounding at the control panel end only.\u003c\/li\u003e\n\u003cli\u003eVerify that the power supply voltage remains strictly within the 18 to 32 VDC range during full operational load conditions to prevent brownout faults.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":48188916727998,"sku":"2108B2001","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/2108B2001.png?v=1784795353","url":"https:\/\/www.autooiltech.com\/products\/honeywell-2108b2001-searchpoint-optima-plus-gas-detector","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
