As a core component of the 3300 XL series, this 8mm proximity probe provides high-fidelity data for fluid-film bearing machines, including high-speed turbines, centrifugal compressors, and critical pumps. This specific model excels in the most demanding Turbine Supervisory Instrumentation (TSI) applications, where sub-micron accuracy is essential for detecting shaft misalignment, imbalance, or oil whirl. By delivering a stable, linear signal to the 3500 monitoring rack, it facilitates real-time asset health analytics and supports emergency shutdown (ESD) protocols. Its ruggedized design ensures that critical machinery remains under constant surveillance, significantly reducing the risk of catastrophic mechanical failure in power generation and petrochemical sectors.\u003c\/p\u003e\n\u003ch2\u003eTransducer Suffix Analysis\u003c\/h2\u003e\n\u003ch3\u003eDecoding the Part Configuration\u003c\/h3\u003e\n\u003cp\u003eThe alphanumeric string 330101-00-72-20-02-00 specifies the precise mechanical and electrical profile required for specialized industrial mounting.\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e-00 (Unthreaded Length):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eRepresents a 0.0-inch unthreaded length, indicating the probe body is fully threaded for maximum depth adjustment.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e-72 (Overall Case Length):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSpecifies a 7.2-inch total case length, designed for deep-reach installation through bearing housings or machine casings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e-20 (Total Length):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDefines a 2.0-meter (approx. 6.6 feet) total cable length, requiring a 3.0-meter or 7.0-meter extension cable to complete a 5m or 9m calibrated system.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e-02 (Connector Option):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFeatures a miniature coaxial connector with a specialized brass cable protector for superior mechanical durability.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e-00 (Agency Approval):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eStandard non-certified option, ideal for general industrial applications where explosion-proof ratings are not mandated.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHardware Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eTechnical Detail\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\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\u003e\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eUSA\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eLinear Range\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e2.0 mm (80 mils)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eNominal Sensitivity\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e7.87 V\/mm (200 mV\/mil)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e-51°C to +177°C (-60°F to +350°F)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eShipping Weight\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0.55 kg (1.21 lbs)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e3\/8-24 UNF thread; 8.0mm tip diameter\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eIngress Protection\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eIP68 (Probe Tip and Case)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eHS Code\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e90318080\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eField Commissioning Protocol\u003c\/h2\u003e\n\u003ch3\u003eGap Voltage Verification\u003c\/h3\u003e\n\u003cp\u003eAchieving peak accuracy requires precise mechanical gapping.
