In the realm of turbomachinery condition monitoring, signal integrity is paramount. This extension cable provides the essential physical bridge between the proximity probe and the Proximitor sensor, ensuring that the high-frequency eddy-current signals are transmitted with minimal attenuation, impedance shift, or electromagnetic interference (EMI). Engineered to meet the rigorous demands of industrial environments, this assembly is a verified component of the Bently Nevada monitoring chain, essential for maintaining the accuracy of rotor dynamics and vibration data required for predictive maintenance strategies.\u003c\/p\u003e\n\u003ch3\u003eTechnical 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\u003e330930-065-04-00\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\u003e0.42 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\u003eCable Type\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eCoaxial\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-35 deg C to +177 deg C\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\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eJacket Material\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eHigh-temperature Fluoropolymer\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eCompatibility\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e3300 NSv Series\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eElectrical Impedance\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eCalibrated System Impedance\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eAgency Approval\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eNot required\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eModel Configuration Explanation\u003c\/h3\u003e\n\u003cp\u003eThe 330930-065-04-00 part number signifies the following physical and electrical configuration parameters:\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e065: Specific assembly style and probe integration interface\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e04: Cable length (4.0 meters)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e00: Connector configuration and non-hazardous area standard\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cp\u003eExtension cables are fundamental to the architecture of large-scale industrial monitoring setups, where the Proximitor sensor must be located at a safe, accessible distance from the machinery casing:\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eSteam and Gas Turbine Monitoring: Connecting probes located in deep housings to externally mounted Proximitors.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCentrifugal Compressors: Managing long cable runs between rotor bearings and control panels.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHigh-Speed Gearboxes: Ensuring clean signal transmission in environments prone to intense electrical noise.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eLaboratory Test Stands: Facilitating modular connections between test rotors and data acquisition racks.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAuxiliary Plant Pumps: Maintaining vibration signal clarity in confined or inaccessible pump mounting locations.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSystem Compatibility\u003c\/h3\u003e\n\u003cp\u003eThe 330930-065-04-00 is strictly part of the 3300 NSv transducer family. It is vital to recognize that the 3300 NSv system is a tuned loop, comprising the probe, the extension cable, and the Proximitor. Because the total system impedance is calibrated to these specific lengths, substituting an extension cable from the 3300 XL (8 mm) series or any legacy system will introduce measurement errors, scaling inaccuracies, and phase shifts. This cable assembly is compatible with 3300 NSv Proximitors and should be integrated into Bently Nevada 3500 series protection systems only when the correct monitor channel configuration for the NSv system is verified.\u003c\/p\u003e\n\u003ch3\u003eInstallation Protocols\u003c\/h3\u003e\n\u003cp\u003eTo maintain the measurement accuracy and reliability of your vibration monitoring system, observe these protocols during installation:\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eConnector Integrity: Ensure both the male and female miniature coaxial connectors are clean, dry, and free of debris.
