This 3300 XL 8 mm eddy current probe measures static and dynamic distances between the probe tip and the observed target, delivering precise vibration and position feedback. It operates seamlessly within Turbine Supervisory Instrumentation (TSI) setups, feeding real-time data directly to Bently Nevada 3500 monitoring racks or distributed control systems (DCS). Industrial facilities deploy this hardware on high-speed rotating machinery like steam turbines, centrifugal compressors, and large pumps to drive continuous condition monitoring and execution of emergency shutdown protocols. The rugged construction minimizes data drift, ensuring survival and signal integrity under relentless thermal and mechanical stress.\u003c\/p\u003e\n\u003ch2\u003eModel Configuration Breakdown\u003c\/h2\u003e\n\u003cp\u003eThe alphanumeric part number specifies precise physical dimensions, cable variables, and agency approval parameters required for drop-in field installation.\u003c\/p\u003e\n\u003ch3\u003eUnthreaded Length Option (-36)\u003c\/h3\u003e\n\u003cp\u003eThis parameter defines a 3.6-inch unthreaded length on the probe case, optimizing deep insertion depths into machine housings while maintaining structural rigidity.\u003c\/p\u003e\n\u003ch3\u003eOverall Case Length Option (-80)\u003c\/h3\u003e\n\u003cp\u003eThe selection specifies an 8.0-inch total case length, providing the necessary reach to bridge the gap between external junction boxes and internal shaft surfaces.\u003c\/p\u003e\n\u003ch3\u003eTotal Length Option (-10)\u003c\/h3\u003e\n\u003cp\u003eThis indicator establishes a 1.0-meter overall cable length, designed to connect directly to an extension cable or proximity sensor housing without unnecessary line slack.\u003c\/p\u003e\n\u003ch3\u003eConnector and Cable Option (-02)\u003c\/h3\u003e\n\u003cp\u003eThe configuration includes a miniature coaxial click-loc connector and standard cable jacket, providing low-impedance signal transmission and resistance to synthetic lubricants.\u003c\/p\u003e\n\u003ch3\u003eAgency Approval Option (-00)\u003c\/h3\u003e\n\u003cp\u003eThis code represents the standard non-approvals option, intended for general industrial environments that do not require specific intrinsic safety certifications.\u003c\/p\u003e\n\u003ch2\u003eHardware and Performance Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eAttribute\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification Details\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\u003eProbe Tip Diameter\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e8 mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eLinear Range\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e2.0 mm (80 mils) starting at roughly 0.25 mm (10 mils) from the target\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eNominal Scale Factor\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e7.87 V\/mm (200 mV\/mil) when paired with 3300 XL Proximitor\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOperating Temperature\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e-51°C to +177°C (-60°F to +351°F)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eEnclosure IP Rating\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eIP68 fully sealed probe head and case assembly\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eProbe Tip Material\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003ePolyphenylene sulfide (PPS)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eCase Material\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eAISI 303 stainless steel\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eShipping Weight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0.35 kg (0.77 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\u003e20.3 cm x 15.2 cm x 5.1 cm (8.0 in x 6.0 in x 2.0 in)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eField Engineering and Installation Procedures\u003c\/h2\u003e\n\u003ch3\u003eTarget Material and Calibration Requirements\u003c\/h3\u003e\n\u003cp\u003eVerify that the target material matches AISI 4140 steel to maintain the calibrated scale factor of 200 mV\/mil.

A reading between -2.0 VDC and -18.0 VDC indicates an active probe within its operating gap. A reading near 0 VDC points to a short circuit, while a reading approaching -24 VDC indicates an open circuit or an excessive gap distance.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eQ2: Does this 1.0-meter probe require a specific extension cable configuration?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eA2: Yes, the 3300 XL 8mm system demands a total system length of either 5.0 meters or 9.0 meters. Because this specific probe has a 1.0-meter integrated cable, you must pair it with a 4.0-meter or 8.0-meter extension cable that matches the specific Proximitor model in use to avoid scale factor distortion.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eQ3: What causes a sudden change in gap voltage when the machine is running at stable load?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eA3: Sudden shifts typically indicate mechanical movement like loose mounting brackets, target shaft migration, or serious shaft babbitt bearing degradation. If mechanical inspection shows everything is tight, inspect the coaxial connectors for oil contamination or moisture ingress, which alters the circuit impedance.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518879260845,"sku":"330101-36-80-10-02-00","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330101-36-80-10-02-00-3300-xl-8-mm-proximity-probes-bwgcr0dhbqf.jpg?v=1766980835","url":"https:\/\/www.maxwellplc.com\/products\/bently-nevada-330101-36-80-10-02-00-3300-xl-8-mm-proximity-probes","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
