The assembly utilizes an eddy-current transducer principle to track rotor radial position, thrust movement, and shaft speed across rotating machinery trains. The probe provides the raw voltage signal interface required by the proximity transducer system to correlate gap distance to physical shaft displacement.\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\u003e330905-00-15-05-02-05\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eBently Nevada\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\u003e0.14 kg (0.31 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Length\u003c\/td\u003e\n\u003ctd\u003e150 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Length\u003c\/td\u003e\n\u003ctd\u003e0.5 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread Size\u003c\/td\u003e\n\u003ctd\u003eM10 x 1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection\u003c\/td\u003e\n\u003ctd\u003eStainless steel armor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-35 deg C to 177 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProximity System\u003c\/td\u003e\n\u003ctd\u003e3300 NSV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eRotor Dynamics and Probe Scaling\u003c\/h3\u003e\n\u003cp\u003eThe 330905 NSV probe system is calibrated for a specific scale factor of 7.87 V\/mm (200 mV\/mil). During installation, the gap voltage must be validated against the standard -10 VDC target, typically centered within the linear range of the probe's characteristic curve. Proper rotor dynamics analysis requires the probe tip to be positioned to accommodate both the expected vibration amplitude and the thermal expansion of the rotor shaft. The M10 x 1 thread configuration necessitates precise axial positioning to maintain the required proximity gap; deviation from the nominal gap setting will shift the DC output bias and can potentially lead to signal clipping or nonlinear response during rotor excursions.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the impact of the integrated armor on the probe's electrical performance?\u003c\/p\u003e\n\u003cp\u003eA: The stainless steel armor provides mechanical protection against debris and fluid exposure but does not affect the inductive sensing core. However, ensure the armor is properly secured to avoid physical contact with the shaft, which could induce noise or measurement artifacts.\u003c\/p\u003e\n\u003cp\u003eQ: Can this probe be interchanged with standard 3300 XL series components?\u003c\/p\u003e\n\u003cp\u003eA: No, the 3300 NSV series utilizes specific probe tip geometry and matching impedance characteristics. It must be paired with the 3300 NSV-specific extension cable and proximitor sensor to maintain system linearity and calibration accuracy.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eEnsure the mounting bracket is rigid to prevent mechanical resonance, which can introduce false vibration readings.\u003c\/li\u003e\n\u003cli\u003eVerify that the shaft surface is clean, free of scratches, and degaussed to prevent eddy-current interference.\u003c\/li\u003e\n\u003cli\u003eUtilize a gap-setting tool to establish the nominal -10 VDC reading at the proximitor output before locking the jam nuts.\u003c\/li\u003e\n\u003cli\u003eRoute the armored cable away from high-voltage AC lines to mitigate electromagnetic interference and potential signal cross-talk.\u003c\/li\u003e\n\u003cli\u003eEnsure the jam nuts are tightened against the mounting bracket to secure the probe position, preventing axial drift due to machine casing vibration.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":53590120759480,"sku":"330905-00-15-05-02-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0935\/6132\/3704\/files\/330905-00-15-05-02-05.png?v=1781495198","url":"https:\/\/www.globalpetroparts.com\/products\/bently-nevada-330905-00-15-05-02-05-proximity-probe","provider":"Global Petro Parts Automation","version":"1.0","type":"link"}
