This eddy current sensor features a 3\/8-24 UNF unarmored thread configuration with an unthreaded length of 1.0 inch and an overall case length of 5.5 inches. Weighing approximately 0.14 kg (0.31 lbs), its lightweight yet rugged construction provides superior side-view characteristics and enhanced chemical resistance, effectively replacing older 3300 RAM and 3000-series 190 probes in centrifugal compressors, pumps, and high-speed rotating machinery.\u003c\/p\u003e\n\n\u003ch2\u003eSuffix Configuration Breakdown\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e330908:\u003c\/strong\u003e 3300 NSv Proximity Probe standard model, 3\/8-24 UNF thread, without armor.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e-10:\u003c\/strong\u003e Unthreaded case length of 1.0 inch.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e-55:\u003c\/strong\u003e Overall case length of 5.5 inches.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e-05:\u003c\/strong\u003e Total electrical cable length of 0.5 meters (20 inches).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e-02:\u003c\/strong\u003e Miniature coaxial ClickLoc connector with standard FEP insulated cable.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e-00:\u003c\/strong\u003e Standard option, no specific agency approvals required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f2f2f2;\"\u003e\n      \u003cth style=\"border: 1px solid #dddddd; padding: 8px; text-align: left;\"\u003eParameter\u003c\/th\u003e\n      \u003cth style=\"border: 1px solid #dddddd; padding: 8px; text-align: left;\"\u003eSpecification Details\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e\u003cstrong\u003eLinear Range\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e1.5 mm (60 mils), spanning from 0.25 to 1.75 mm (10 to 70 mils)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e\u003cstrong\u003eIncremental Scale Factor (ISF)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e7.87 V\/mm (200 mV\/mil) +12.5% \/ -20%\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e\u003cstrong\u003eRecommended Gap Setting\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e1.0 mm (40 mils), equivalent to approximately -9 Vdc\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e\u003cstrong\u003eFrequency Response\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e0 to 10 kHz; +0, -3 dB typical (up to 305m field wiring)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e\u003cstrong\u003eProbe DC Resistance\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e4.0 ± 0.5 Ω (Center conductor to outer conductor)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e\u003cstrong\u003eTip \u0026amp; Case Material\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003ePolyphenylene sulfide (PPS) tip \/ AISI 304 Stainless Steel case\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e\u003cstrong\u003eProduct Net Weight\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eApprox. 0.14 kg (0.31 lbs)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e-52°C to +177°C (-62°F to +351°F)\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eInstallation \u0026amp; Maintenance\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGap Voltage Target:\u003c\/strong\u003e Set the initial physical gap to 1.0 mm (40 mils) during installation, which corresponds to the midpoint of the linear output voltage slope (approx. -9 Vdc).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorque Constraints:\u003c\/strong\u003e Tighten the probe case to a recommended 11.3 N·m (100 in·lb), never exceeding the maximum rating of 33.9 N·m (300 in·lb).

For field wiring to the monitor (up to 305 meters), a three-conductor shielded triad cable between 0.2 to 1.5 mm² (16 to 24 AWG) is highly recommended.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Is the pressure seal of the 330908 probe factory-tested prior to shipping?\u003c\/strong\u003e\u003cbr\u003e\nA2: No. While the integrated Viton O-ring is engineered to seal differential pressure between the tip and case, these probes are not pressure-tested before shipment unless explicitly requested via custom design orders.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: How does a target shaft smaller than the recommended 13 mm alter performance?\u003c\/strong\u003e\u003cbr\u003e\nA3: Shafts smaller than 13 mm (0.5 in) reduce the visible target area, causing a shift in the Incremental Scale Factor (ISF). You can mitigate this scale factor deviation by reducing the operational gap distance between the probe tip and the shaft target.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":51869262774404,"sku":"330908-10-55-05-02-00","price":130.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/330908-10-55-05-02-00.jpg?v=1779200727","url":"https:\/\/www.etowonauto.com\/tk\/products\/330908-10-55-05-02-00-bently-nevada-3300-nsv-eddy-current-probe","provider":"Etowon Auto","version":"1.0","type":"link"}
