Specifically engineered for small-shaft rotating machinery, this 5 mm diameter probe utilizes eddy-current induction to provide high-resolution displacement data. Unlike standard 8 mm XL probes, the 330903 is optimized for tighter clearances and lower-vibration amplitude environments, ensuring accurate radial vibration and axial position measurement in compact industrial equipment.\u003c\/p\u003e\n\u003ch3\u003eSuffix Breakdown \u0026amp; Model Matrix\u003c\/h3\u003e\n\u003cp\u003eThe 330903-04-10-10-01-00 assembly is configured to meet specific installation requirements:\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e04: Thread size\/style (5\/8-24 UN-2A)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e10: Overall case length (100 mm)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e10: Total length (1.0 meter)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e01: Connector type (Miniature coaxial, non-armored)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e00: Agency approval (Standard)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eModel\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e330903-04-10-10-01-00\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eBrand\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eBently Nevada\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOrigin\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\u003eWeight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0.30 kg\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\u003e30 x 25 x 10 cm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eProbe Diameter\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e5 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\u003e1.5 mm (60 mil)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOperating Temp\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e-35 deg C to +177 deg C\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003ePower Consumption\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003ePassive (Loop powered)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eConnector Type\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eMiniature Coaxial\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eMechanical Monitoring \u0026amp; TSI Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe 3300 NSv system is designed for machinery where space constraints or small shaft diameters preclude the use of larger 8 mm transducers. The system's sensitivity is factory-tuned to 7.87 V\/mm (200 mV\/mil), providing the high gain necessary to detect subtle rotor dynamics. During commissioning, the probe must be gapped to the mid-point of the linear range, typically verified by observing a -10 VDC output at the Proximitor sensor. Proper installation is critical for signal linearity; any mechanical resonance in the probe mounting bracket or proximity to metallic surfaces can induce unwanted signal artifacts.\u003c\/p\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e330903 5 mm NSv Proximity Probe\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eInstallation hardware package (Locknut and washer)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eProduct technical data sheet\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eNote: This probe requires a matched 3300 NSv Proximitor to function within specified accuracy limits.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eGap Setting: Use a precision feeler gauge to set the gap.
