This specialized 3300 XL 11mm transducer tracks key physical parameters, including large-scale radial shaft vibration, axial thrust position, and differential casing expansion. The rugged head projects a wide, stable eddy current field that effortlessly measures wider displacement spans where smaller 8mm sensors would experience signal saturation or clipping. It transfers unbuffered voltage telemetry straight into Bently Nevada 3500 monitoring racks and main plant Distributed Control Systems (DCS). Reliability managers deploy this armored variant to provide critical, real-time diagnostic inputs for automated emergency shutdown (ESD) loops, safeguarding high-capital steam turbines, massive hydro-generators, and high-pressure process compressors from catastrophic mechanical failures.\u003c\/p\u003e\n\u003ch2\u003eModel Configuration \u0026amp; Functional Suffix Breakdown\u003c\/h2\u003e\n\u003cp\u003eThe distinct alphanumeric characters within this model number code define the precise physical housing layout, integrated steel armor protection, and explosion-proof regulatory compliance.\u003c\/p\u003e\n\u003ch3\u003e000 - Casing Thread Profile\u003c\/h3\u003e\n\u003cp\u003eThe triple-zero parameter selects a 0 mm unthreaded length configuration.

Because the 11mm tip generates a wider electromagnetic field than standard 8mm models, maintain a minimum of 25.4 mm (1.0 inch) of radial clearance from any surrounding structural steel counter-bores or machine side-walls to eliminate parasitic side-loading interference. Lock the ClickLoc connection securely and seal it inside an external conduit junction box to isolate the terminal from corrosive airborne contaminants.\u003c\/p\u003e\n\u003ch2\u003eSevere-Environment Performance \u0026amp; TSI Architecture Integration\u003c\/h2\u003e\n\u003cp\u003eThe 330704 series probe withstands punishing industrial conditions, utilizing a polyphenylene sulfide (PPS) tip face that resists degradation from caustic chemical vapors, steam leaks, and high-temperature synthetic lubricants.

This direct hardware compatibility allows the control layer to compute complex orbit plots, structural vibration vectors, and cross-phase transients, providing operators with immediate notice of oil whip, shaft unbalance, or thrust bearing deterioration.\u003c\/p\u003e\n\u003ch2\u003eOrder Fulfillment Manifest\u003c\/h2\u003e\n\u003cp\u003e(1) One genuine Bently Nevada 330704-000-050-10-02-05 3300 XL 11mm armored proximity probe.\u003c\/p\u003e\n\u003cp\u003e(2) Integrated 1.0-meter coaxial cable protected by flexible interlocking stainless steel armor.\u003c\/p\u003e\n\u003cp\u003e(3) Attached miniature coaxial ClickLoc connector socket.\u003c\/p\u003e\n\u003cp\u003e(4) Original inspection and safety certificate indicating ATEX, CSA, and IECEx parameters.\u003c\/p\u003e\n\u003ch2\u003eHigh-Protection Dispatch Logistics\u003c\/h2\u003e\n\u003cp\u003eOur international logistics facility prepares and routes orders within 2-7 days after payment finish protocols are confirmed. We coordinate global transport through premium express networks, including DHL, FEDEX, and UPS, to ensure rapid, fully tracked delivery directly to your industrial site. Prior to dispatch, technicians run physical checks and seal each probe into heavy-duty anti-static industrial packaging. This ESD-shielded, shock-absorbent container protects the long 115.5 cm shipping profile, the internal sensing coils, and the interlocking steel armor from physical deformation and electrostatic hazards during travel, delivering the component ready for immediate field installation.\u003c\/p\u003e\n\u003ch2\u003eMachinery Instrumentation FAQs\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: Why does this specific probe model utilize a larger 11mm tip diameter instead of a standard 8mm tip?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA1: The 11mm tip diameter produces a larger, deeper electromagnetic field, which provides a nominal linear measurement range of 4.0 mm (160 mils). This is twice the measuring range of a standard 8mm sensor, making it ideal for large-scale machines with higher expected shaft movements, such as structural differential expansion loops on steam turbines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Can I connect this 330704 armored probe directly to a standard 3300 XL 8mm Proximitor Sensor?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA2: No. The internal inductance properties and calibrated scale factor of the 11mm probe are entirely different from the 8mm family. It outputs a nominal scale factor of 100 mV\/mil instead of the standard 200 mV\/mil. Connecting this probe to an 8mm Proximitor creates severe calibration mismatches and renders the safety monitoring loop useless.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: How can a technician test the internal induction coil for damage using a multimeter?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA3: Disconnect the probe from the main extension cable line. Touch the multimeter leads to the center pin and the outer body of the ClickLoc connector to check resistance. A healthy 3300 XL 11mm probe with a 1.0-meter lead typically registers a stable DC resistance value between 5.0 and 11.0 ohms; a reading of near zero indicates a short circuit, while an infinite reading indicates an internal break.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: Does the interlocking stainless steel armor eliminate the need for external conduits?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA4: The integrated armor provides strong local protection against physical impacts, pinching, and abrasion inside or immediately outside the machine housing. However, once the cable leaves the immediate machine vicinity to route back to the main instrument panel, you should still run it through dedicated metallic conduits to shield it from external electromagnetic noise and major environmental hazards.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518881849517,"sku":"330704-000-050-10-02-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330704-000-050-10-02-05-3300-xl-11-mm-proximity-probes-unydftjsj13.jpg?v=1766980917","url":"https:\/\/www.maxwellplc.com\/products\/bently-nevada-330704-000-050-10-02-05-3300-xl-11mm-armored-proximity-probe","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
