The Bently Nevada 330930-060-11-00 represents the pinnacle of protection for 3300 NSv proximity transducer systems. Specifically, this 6.0-meter (19.7 feet) extension cable combines three critical protective features: FluidLoc technology prevents oil leakage, stainless steel armor guards against physical damage, and a connector protector shields against moisture. Furthermore, this cable is manufactured in the U.S.A. with 75 Ω coaxial FEP insulation, ensuring reliable signal transmission for vibration and position monitoring in the most demanding applications. Consequently, this model is the preferred choice for turbomachinery, compressors, and other critical rotating equipment.
The 330930-060-11-00 delivers consistent electrical performance essential for accurate machinery protection. For instance, its typical extension cable capacitance measures 69.9 pF/m (21.3 pF/ft), ensuring signal integrity across the 6.0-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), providing excellent conductivity.
Moreover, this cable utilizes 75 Ω coaxial construction with fluoroethylene propylene (FEP) insulation, which offers 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 Bently Nevada 330930-060-11-00 incorporates FluidLoc technology, which provides a critical barrier against oil and process liquid migration. Specifically, this feature prevents fluids from leaking out of the machine through the cable's interior, a common failure point in traditional cable designs. This capability proves essential in turbine and compressor applications where oil leakage poses significant safety, environmental, and operational risks. Furthermore, the FluidLoc option eliminates the need for additional sealing compounds, simplifying installation while enhancing long-term reliability.
This model features the "11" 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 crushing, abrasion, and impact damage. This armor is particularly valuable in retrofit applications where cables may be routed through tight spaces or exposed to mechanical hazards. Additionally, 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 operation.
The 330930-060-11-00 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.
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). Furthermore, for hazardous area applications, the cable meets various temperature classifications:
For EPL Ga and Gc:
T1: -55°C to +232°C
T2: -55°C to +177°C
T3: -55°C to +120°C
T4: -55°C to +80°C
T5: -55°C to +40°C
For EPL Dc:
T280°C: -55°C to +232°C
T225°C: -55°C to +177°C
T170°C: -55°C to +120°C
T130°C: -55°C to +80°C
T105°C: -55°C to +100°C
T90°C: -55°C to +40°C
This comprehensive temperature compliance makes the 330930-060-11-00 suitable for a wide range of hazardous area installations worldwide.
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 system length options are 5 or 7 meters including the extension cable. Therefore, if your system requires a 7-meter total length and you use a 1-meter probe, you would select a 6-meter extension cable like the 330930-060-11-00. Always verify your existing probe length before ordering to ensure proper system configuration.
The 330930-060-11-00 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. The Proximitor Sensor material is A380 aluminum, providing durability and consistent thermal performance.
Installing the Bently Nevada 330930-060-11-00 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.
