This highly specialized, extra-long variant targets massive industrial turbomachinery, such as double-wall steam turbines or deeply recessed centrifugal compressors, where thick thermal insulation blankets demand extended mechanical reach. By maintaining absolute structural rigidity, the housing isolates the internal proximity probe from high-pressure oil mist, corrosive atmospheric agents, and extreme mechanical stresses. It interfaces directly with Bently Nevada 3500 rack architectures and plant-wide Distributed Control Systems (DCS), ensuring the transmission of clean, uninterrupted shaft vibration and axial position data. Critical emergency shutdown systems (ESD) rely on this precise mechanical stabilization to eliminate signal drift and prevent catastrophic asset failures.\u003c\/p\u003e\n\u003ch2\u003eModel Configuration Breakdown\u003c\/h2\u003e\n\u003ch3\u003e21000 - Product Nomenclature\u003c\/h3\u003e\n\u003cp\u003eSpecifies the standard certified aluminum proximity probe housing series designed for explosion-proof and flame-proof industrial installations.\u003c\/p\u003e\n\u003ch3\u003e16 - Conduit Entry Thread\u003c\/h3\u003e\n\u003cp\u003eConfigures a 3\/4-14 NPT conduit connection with an integrated internal plastic cable grip for robust field wiring security.\u003c\/p\u003e\n\u003ch3\u003e10 - Internal Probe Thread Profile\u003c\/h3\u003e\n\u003cp\u003eMachining specification choosing a 3\/8-24 UNF internal thread to accept matching standard proximity probe sleeves.\u003c\/p\u003e\n\u003ch3\u003e00 - Structural Seat Option\u003c\/h3\u003e\n\u003cp\u003eDefines a completely flat mounting seat option without any specialized counterbore modifications or step flanges.\u003c\/p\u003e\n\u003ch3\u003e244 - Standoff Length Profile\u003c\/h3\u003e\n\u003cp\u003eIndicates a precise, extra-extended 24.4-inch total standoff distance to bridge vast mechanical clearance gaps on massive machinery casings.\u003c\/p\u003e\n\u003ch3\u003e04 - Probe Penetration Variable\u003c\/h3\u003e\n\u003cp\u003eProvides a maximum of 4.0 inches of internal linear sleeve travel for precise field depth adjustments relative to the shaft target.\u003c\/p\u003e\n\u003ch3\u003e02 - Field Hardware Coupling\u003c\/h3\u003e\n\u003cp\u003eEquips the housing package with standard external explosion-proof field wiring adapters for immediate on-site conduit mating.\u003c\/p\u003e\n\u003ch2\u003eMechanical and Environmental Parameters\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eManufacturer\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eBently Nevada (Baker Hughes)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003ePart Number\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e21000-16-10-00-244-04-02\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eCountry of Origin\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eUnited States\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eEnclosure Material\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eCopper-Free Cast Aluminum\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eUnit Net Weight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e2.58 kg (5.69 lbs)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eShipping Dimensions\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e720 mm x 180 mm x 150 mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eHarmonized Tariff Code (HS Code)\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e9031900090\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eAmbient Temperature Rating\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e-40°C to +100°C (-40°F to +212°F)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eTotal Adjustable Travel\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0.0 to 4.0 Inches Internal Penetration\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eEnvironmental Protection Code\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eIP66 \/ NEMA 4X Rated\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eHazardous Approvals\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eATEX, IECEx, Class I Division 1 Certified\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eOn-Site Engineering Installation Protocols\u003c\/h2\u003e\n\u003ch3\u003eMechanical Deflection Prevention\u003c\/h3\u003e\n\u003cp\u003eDue to the ultra-extended 24.4-inch standoff length, verify that the structural mounting boss on the machine casing is completely rigid.
