The Bently Nevada 330930-040-03-CN is a specialized extension cable engineered for the 3300 NSv proximity transducer system. Specifically, this 4.0-meter (13.1 feet) cable connects the NSv probe to the Proximitor Sensor, ensuring reliable signal transmission for vibration and position monitoring. Furthermore, it includes a connector protector that shields connections from humidity and moisture, making it suitable for demanding industrial environments. Manufactured in the U.S.A., this cable delivers consistent performance backed by Bently Nevada's renowned quality standards.
The 330930-040-03-CN offers precise electrical characteristics for accurate data acquisition. For instance, its typical extension cable capacitance measures 69.9 pF/m (21.3 pF/ft), maintaining signal fidelity across the 4.0-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).
Moreover, this cable utilizes 75 Ω coaxial construction with fluoroethylene propylene (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 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.
The Bently Nevada 330930-040-03-CN 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, this model features the "03" connector and cable option, which means it comes without stainless steel armor but includes a connector protector. The cable material consists of 75 Ω coaxial FEP insulation, providing flexibility and durability. Regarding mechanical strength, the tensile rating reaches 220 N (50 lb) for the probe case, probe lead connectors, and stainless steel armor connections. Additionally, the total shipping weight is 1.5 kg, which includes all packaging materials.
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, if your system requires a 9-meter total length and you use a 5-meter probe, you would select a 4-meter extension cable like the 330930-040-03-CN. Therefore, always verify your existing probe length before ordering to ensure compatibility.
The 3300 NSv extension cable works within a 1.5 mm (60 mils) linear range for vibration monitoring. 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. Meanwhile, the incremental scale factor provides consistent sensitivity across the measurement range, ensuring accurate vibration data for machinery protection systems.
The 330930-040-03-CN includes a connector protector as standard with the "03" option. This component provides additional protection of the connectors in humid or moist environments. Additionally, connector protectors are recommended for all installations as they increase environmental protection and prevent contamination from dust and moisture. 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.
Installing the Bently Nevada 330930-040-03-CN 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, refer to the frequency response graphs (Figure 16 and Figure 17) for signal rolloff characteristics when using longer field wiring lengths up to 305 meters.
