This specialized eddy current sensor targets restricted installations where tight physical clearances and small shaft targets prevent the deployment of standard-sized proximity probes.\u003c\/p\u003e\n\u003cp\u003eReliability engineers install this high-accuracy sensor loop inside comprehensive Turbine Supervisory Instrumentation (TSI) layouts to track radial vibration, axial thrust movement, and rotational speed parameters on small steam turbines, high-speed turbo-compressors, centrifugal pumps, and auxiliary plant machinery. The specialized sensor face passes an exceptionally clean, low-noise analog signal directly to automated machinery protection systems. This continuous telemetry feeds central DCS interlocks and emergency shutdown loops with the responsive tracking data required to execute critical trips instantly before catastrophic bearing or structural breakdown occurs.\u003c\/p\u003e\n\u003ch2\u003ePart Number Option Block Breakdown\u003c\/h2\u003e\n\u003ch3\u003e330903 [3300 NSv 1\/4-28 UNF Threaded Baseline]\u003c\/h3\u003e\n\u003cp\u003eIdentifies the baseline hardware series as a high-precision 3300 NSv proximity probe featuring an imperial 1\/4-28 UNF external thread profile, optimized for tight structural mounting configurations.\u003c\/p\u003e\n\u003ch3\u003e-00 [Unthreaded Length Segment]\u003c\/h3\u003e\n\u003cp\u003eSpecifies a 0.0-inch unthreaded barrel configuration, ensuring cut threads extend fully across the casing sleeve to maximize physical depth adjustment capabilities during field deployment.\u003c\/p\u003e\n\u003ch3\u003e-04 [Overall Case Length Segment]\u003c\/h3\u003e\n\u003cp\u003eEstablishes the total threaded case length at 0.4 inches, providing a highly compact, low-profile probe body ideal for specialized bearings or limited-space machine cavities.\u003c\/p\u003e\n\u003ch3\u003e-05 [Total Cable Length Segment]\u003c\/h3\u003e\n\u003cp\u003eDefines a 0.5-meter (1.6 feet) integrated coaxial cable length, measured precisely from the molded sensor head tip to the male miniature connection terminal.\u003c\/p\u003e\n\u003ch3\u003e-02 [Stainless Steel Armor Option]\u003c\/h3\u003e\n\u003cp\u003eEquips the integrated coaxial lead line with a flexible, fluid-tight stainless steel armor jacket over its entire physical length to shield the internal dielectric structure from tearing, crushing, or severe mechanical abrasion.\u003c\/p\u003e\n\u003ch3\u003e-05 [Global Safety Framework Authorization]\u003c\/h3\u003e\n\u003cp\u003eCarries comprehensive international hazardous area certifications, including ATEX, IECEx, and North American standard approvals, enabling secure deployment within intrinsically safe industrial zones.\u003c\/p\u003e\n\u003ch2\u003ePhysical Attributes \u0026amp; Operating Limits\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\u003eCertified Field Performance Values\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\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\u003eHS Code\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e90318080\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eTotal Component Weight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0.32 kg (0.71 lbs)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eShipping Carton Dimensions\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e175 mm x 175 mm x 60 mm (6.9 in x 6.9 in x 2.4 in)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eLinear Sensing Envelope\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e1.52 mm (60 mils) nominal linear range tracking target area\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eTransducer Scale Factor\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e7.87 V\/mm (200 mV\/mil) when combined with 3300 NSv Proximitor\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOperational Temperature Window\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e-51°C to +177°C (-60°F to +350°F) for probe head and cable\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eProtective Ingress Class\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eIP68 \/ NEMA 4X certified hermetic fluid sealing\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eSite Positioning \u0026amp; Mechanical Alignment Manual\u003c\/h2\u003e\n\u003cp\u003eField instrumentation specialists must establish precise mechanical gap spacing using a digital voltmeter during deployment due to the compact nature of the 3300 NSv system target. Thread the 0.4-inch probe barrel slowly into the machine housing port while monitoring the raw DC gap voltage at the corresponding 3300 NSv Proximitor test terminals. Rotate the probe body until the meter reads approximately -9.0 VDC, which corresponds to the exact mid-point calibration value of the 1.52 mm linear tracking band.\u003c\/p\u003e\n\u003cp\u003eMaintain a strict minimum bend radius of 25.4 mm (1.0 inch) along the armored coaxial line to prevent internal core kinking or structural signal attenuation. Route the armored line through dedicated, grounded instrument raceways to isolate the low-voltage analog signal from nearby high-voltage lines. Technicians must verify that the selected extension cable pairs correctly with this 0.5-meter probe to match the exact total electrical loop length required by the remote Proximitor module.\u003c\/p\u003e\n\u003ch2\u003eMechanical Durability \u0026amp; Infrastructure Integration\u003c\/h2\u003e\n\u003cp\u003eThe advanced engineering of the 3300 NSv probe utilizes a specialized high-performance composite tip material molded directly over the internal eddy current sensing coil to create an airtight barrier.

Pairing it with a standard 3300 XL 8mm Proximitor creates a major impedance mismatch, which de-calibrates the system and yields completely invalid voltage outputs. You must use a dedicated 3300 NSv Proximitor sensor module.\u003c\/p\u003e\n\u003ch3\u003eQ2: What specific installation advantage does the -02 stainless steel armor option offer?\u003c\/h3\u003e\n\u003cp\u003eA2: The stainless steel armor option provides excellent physical defense against mechanical crushing, sharp tool cuts, and abrasive wear within the machine housing. It allows you to route the probe line safely across exposed machine components without risking an open-circuit fault from physical impacts.\u003c\/p\u003e\n\u003ch3\u003eQ3: Why does this probe utilize a shorter linear tracking range (1.52 mm) than standard 8mm probes?\u003c\/h3\u003e\n\u003cp\u003eA3: The shorter 1.52 mm (60 mils) linear range is an intentional engineering tradeoff required to achieve a smaller physical probe tip diameter. The compact tip layout focuses the eddy current field into a tighter zone, allowing the sensor to track dynamic shaft behavior accurately next to large counterbores, narrow collars, or tight physical obstructions that would disrupt a standard 8mm probe field.\u003c\/p\u003e\n\u003ch3\u003eQ4: What action should I take if the Proximitor signal registers a constant -24 VDC saturation voltage?\u003c\/h3\u003e\n\u003cp\u003eA4: A constant -24 VDC output almost always indicates an open-circuit error within the sensor loop. Check the miniature ClickLoc connection between the probe lead and the extension cable for a loose coupling or moisture entry. Use a digital multimeter to verify the center-conductor-to-shield continuity along the line to locate the break.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518868185261,"sku":"330903-00-04-05-02-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330903-00-04-05-02-05-3300-nsv-proximity-probes-qrjmycdk1es.jpg?v=1766980589","url":"https:\/\/www.maxwellplc.com\/products\/bently-nevada-330903-00-04-05-02-05-3300-nsv-proximity-displacement-probe","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
