The Bently Nevada 330930-065-05-00 is a high-performance extension cable engineered for the 3300 NSv proximity transducer system. Specifically, this 6.5-meter (21.3 feet) cable connects the NSv probe to the Proximitor Sensor, ensuring accurate signal transmission for vibration and position monitoring applications. Furthermore, it features stainless steel armor without an FEP outer jacket, providing excellent physical protection against crushing and abrasion. Additionally, the included connector protector shields connections from humidity and moisture, making this cable ideal for harsh industrial environments including turbines, compressors, and pumps.
The 330930-065-05-00 delivers precise electrical characteristics essential for accurate machinery protection. For instance, its typical extension cable capacitance measures 69.9 pF/m (21.3 pF/ft), maintaining signal integrity across the 6.5-meter length. Additionally, the DC resistance for the center conductor is rated at 0.220 Ω/m (0.067 Ω/ft), while the shield resistance sits at 0.066 Ω/m (0.020 Ω/ft), ensuring excellent conductivity.
Moreover, this cable utilizes 75 Ω coaxial construction with fluoroethylene propylene (FEP) insulation, which provides outstanding dielectric properties and thermal stability. The connector material features gold-plated brass, delivering superior corrosion resistance and reliable electrical contact. Meanwhile, the system supports field wiring from 0.2 to 1.5 mm² (16 to 24 AWG), with a maximum extension of 305 meters between the Proximitor Sensor and the monitor. However, always refer to the frequency response graphs (Figure 16 and Figure 17) for signal rolloff characteristics when using longer field wiring lengths.
The 330930-065-05-00 features the "05" connector and cable option, which includes stainless steel armor without an FEP outer jacket. Firstly, the flexible AISI 302 SST armor provides exceptional protection against mechanical damage including crushing, impact, and abrasion. This armor proves invaluable in retrofit applications where cables may be routed through tight spaces or exposed to potential physical hazards. Furthermore, the armor maintains flexibility for easy installation while delivering robust protection. The tensile strength is rated at 220 N (50 lb) for the probe case, probe lead connectors, and stainless steel armor connections, ensuring durability during installation and long-term operation.
The Bently Nevada 330930-065-05-00 includes a connector protector as standard equipment. This component provides additional protection of the connectors in humid or moist environments, preventing contamination from dust and moisture that could degrade signal quality. Bently Nevada actually recommends connector protectors for all installations, as they significantly increase environmental protection. While silicone tape is provided as an alternative sealing method, it is not recommended in applications where the connection will be exposed to turbine oil, as degradation may occur over time. Therefore, the connector protector offers a more reliable long-term solution.
The 3300 NSv extension cable operates reliably across extreme temperature ranges. Specifically, its operating and storage temperature spans from -51°C to +177°C (-60°F to +351°F). This wide range makes the cable suitable for high-temperature turbine applications and cold weather installations alike.
Furthermore, the cable material consists of 75 Ω coaxial FEP insulation, providing excellent dielectric properties and thermal stability. The connector material features gold-plated brass, which offers superior corrosion resistance and ensures reliable electrical contact. Meanwhile, the cable's robust construction ensures consistent performance even in challenging environmental conditions, making it a trusted choice for critical machinery monitoring.
Proper system configuration requires careful attention to total length. Firstly, you must ensure that the extension cable length and the probe length, when added together, equal the Proximitor Sensor total length. This matching is critical for maintaining proper calibration and linear range performance. For instance, the 330930-065-05-00 at 6.5 meters provides flexibility for various system configurations. Therefore, always verify your existing probe length before ordering to ensure proper system configuration.
The 330930-065-05-00 operates within a 1.5 mm (60 mils) linear range for vibration monitoring applications. Specifically, this linear range begins at approximately 0.25 mm (10 mils) from the target and extends from 0.25 to 1.75 mm (10 to 70 mils), producing approximately -1 to -13 Vdc output. Consequently, the recommended gap setting is 1.0 mm (40 mils) for optimal performance. This linear range provides excellent sensitivity for detecting vibration and position changes in rotating machinery.
Installing the Bently Nevada 330930-065-05-00 requires attention to several key factors. Initially, power down the monitoring system before making any connections. Next, verify the total system length by adding the probe length and extension cable length to match the Proximitor Sensor rating. Meanwhile, ensure the gold-plated brass connectors are fully engaged and secured.
Furthermore, when extending field wiring beyond the cable, use three-conductor shielded triad cable with appropriate gauge. The recommended field wiring size ranges from 0.2 to 1.5 mm² (16 to 24 AWG), with ferrules recommended for 18 to 23 AWG. Finally, for installations in hazardous areas, always verify that the ambient temperature does not exceed the classification limits specified for your application.
