This Bently Nevada 330930-045-01-00 belongs to the 3300 NSv series and serves as a precision extension cable for proximity measurement systems. It establishes a reliable connection between the 3300 NSv probe and the Proximitor Sensor. Additionally, this model includes stainless steel armor with a FEP outer jacket for enhanced mechanical protection. The cable measures exactly 4.5 meters (14.8 feet) in length, providing flexibility for various installation layouts. High-quality 75Ω coaxial construction ensures consistent signal integrity throughout its service life. Consequently, this component plays an essential role in vibration and position monitoring applications requiring the NSv system's higher resolution.
The Bently Nevada 330930-045-01-00 delivers precise electrical performance for accurate system measurements. Its typical extension cable capacitance measures 69.9 pF/m (21.3 pF/ft) . The center conductor DC resistance registers at 0.220 Ω/m (0.067 Ω/ft) , while the shield resistance reads 0.066 Ω/m (0.020 Ω/ft) . These electrical parameters guarantee consistent operation within the 3300 NSv system architecture. Moreover, the cable utilizes a 75 Ω coaxial, fluoroethylene propylene (FEP) insulated construction. This insulation material offers excellent dielectric strength and resists chemical attack effectively. Gold-plated brass connectors provide superior corrosion resistance and maintain reliable signal contact over time.
This armored extension cable withstands severe operating conditions with ease. The flexible armor consists of AISI 302 stainless steel with a FEP outer jacket, delivering exceptional protection against mechanical stress. Its operating and storage temperature range extends from -51°C to +177°C (-60°F to +351°F) . The cable weighs approximately 1.5 kg in total for the 4.5-meter length. The tensile strength rating reaches 220 N (50 pounds) at all critical connection points, including the probe case to probe lead, probe lead to extension cable connectors, and probe case to stainless steel armor. This robust construction ensures reliable performance in demanding industrial environments.
This 330930-045-01-00 cable integrates smoothly into the complete 3300 NSv monitoring ecosystem. When selecting system components, ensure that the extension cable length and probe length add together to equal the Proximitor Sensor total length. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) conductors, with a maximum permissible length of 305 meters (1,000 feet) between the 3300 XL NSv Proximitor Sensor and the monitor. Specifically, the linear range spans 1.5 mm (60 mils) , starting at approximately 0.25 mm (10 mils) from the target surface. The recommended gap setting is 1.0 mm (40 mils) . The NSv system offers higher sensitivity compared to standard 3300 XL systems, making it ideal for applications requiring finer measurement resolution.
Installing the Bently Nevada 330930-045-01-00 follows a straightforward process when you adhere to standard procedures. First, clean the cable connectors thoroughly and check for debris before mating them with the probe and Proximitor Sensor. Next, route the cable along a path that avoids sharp bends or excessive pulling force, as these conditions could damage the armor or internal conductors. Ensure that the total system length matches the Proximitor Sensor's specified requirements by adding the probe length and extension cable length correctly. Furthermore, the 3300 NSv probe comes with appropriate mounting hardware for secure installation. Finally, tighten all connections to the specified torque values to preserve system integrity. For humid or moist environments, we recommend using connector protectors for additional sealing.

1. What is the difference between the 3300 NSv and standard 3300 XL extension cables?
The 3300 NSv system offers higher sensitivity with a linear range of 1.5 mm compared to the 4.0 mm range of standard 3300 XL systems. The NSv cable uses 75Ω coaxial construction and suits applications requiring finer measurement resolution.
2. What is the exact length of the Bently Nevada 330930-045-01-00 cable?
This cable has a fixed length of 4.5 meters, which equals approximately 14.8 feet. It belongs to the 3300 NSv system and does not allow field shortening or extension.
3. How do I ensure proper total system length with this extension cable?
Add the extension cable length and the probe length together to equal the Proximitor Sensor total length. For example, a 4.5-meter extension cable requires a probe length that completes the system length specified by your Proximitor Sensor.
4. Can this armored cable handle high-temperature applications?
Yes, this cable operates reliably from -51°C to +177°C, making it suitable for turbine and compressor environments. The FEP jacket and stainless steel armor provide excellent thermal and mechanical protection.
5. What are the tensile strength ratings for this extension cable?
The tensile strength rating reaches 220 N (50 pounds) at all connection points, including the probe case to probe lead, probe lead to extension cable connectors, and probe case to stainless steel armor.
