Bently Nevada 330930-045-06-00 3300 NSv Extension Cable

Bently Nevada 330930-045-06-00 3300 NSv Extension Cable

Product Introduction

The Bently Nevada 330930-045-06-00 serves as a high-performance extension cable for the 3300 NSv proximity probe system. This model features the FluidLoc cable option, which effectively prevents oil and other process fluids from leaking through the cable interior. Unlike some variants, this version comes without stainless steel armor, making it lighter and more flexible for easy routing. The "045" length code signifies a 4.5-meter (14.8 feet) cable, which suits a wide range of installation scenarios. Its coaxial FEP insulation provides excellent dielectric properties and chemical resistance. Manufactured in the U.S.A., this cable delivers reliable signal transmission in demanding turbomachinery monitoring applications.

Technical Specifications & Performance

The 330930-045-06-00 offers precise electrical characteristics for accurate measurements. Its typical capacitance measures 69.9 pF/m (highlighted in red) , which maintains signal integrity throughout the measurement chain. The DC resistance for the center conductor registers at 0.220 Ω/m (0.067 Ω/ft) (highlighted in red) , while the shield resistance reads 0.066 Ω/m (0.020 Ω/ft) (highlighted in red) . These low resistance values minimize signal loss and ensure clean data transmission. The cable uses a 75 Ω coaxial configuration, providing effective shielding against electromagnetic interference. Moreover, the entire system maintains linearity across a 1.5 mm (60 mils) range, beginning at approximately 0.25 mm (10 mils) from the target.

FluidLoc Feature and Cable Configuration

This particular model of the 3300 NSv extension cable includes the FluidLoc option as a key differentiator. The FluidLoc design creates a positive seal at the connection points, stopping oil and other liquids from escaping through the cable interior. This feature proves critical for applications where the probe-to-extension cable connection faces constant exposure to lubricants or process fluids. The "06" connector and cable option specifies FluidLoc cable without stainless steel armor, resulting in a more flexible and lighter cable weighing significantly less than armored versions. For environments where the connection will encounter turbine oil, this FluidLoc option provides essential protection.

Mechanical Properties and Temperature Range

The cable's construction ensures durability across a broad spectrum of operating conditions. FEP insulation offers superior dielectric strength and resists degradation from chemicals and heat. The unarmored cable provides excellent flexibility, simplifying installation in tight spaces. The operating temperature spans -51°C to +177°C (-60°F to +351°F) (highlighted in red) , making it suitable for high-temperature environments. Furthermore, the cable features a tensile strength rating of 220 N (50 lb) (highlighted in red) at the connectors, ensuring robust mechanical reliability. Gold-plated brass connectors provide corrosion resistance and secure electrical contact, preventing signal degradation over time.

Compatibility and System Integration

This extension cable integrates seamlessly with the 3300 NSv transducer system. It connects to 3300 NSv probes and Proximitor sensors, forming a complete monitoring solution. When selecting components, ensure that the extension cable length and the probe length add together to match the Proximitor Sensor total length. For field wiring between the Proximitor sensor and the monitor, we recommend using a three-conductor shielded triad cable, with a maximum run of 305 meters (1,000 feet). The system also tolerates 60 Hz magnetic fields up to 300 Gauss, with minimal output voltage variation across different gap settings.

Installation Guidelines

Installing the Bently Nevada 330930-045-06-00 requires attention to a few important steps. First, always power down the system before making any connections. Next, verify that the total length of the probe plus the extension cable matches your Proximitor sensor's specified total length. Then, connect the extension cable to the probe and the Proximitor sensor, ensuring the gold-plated connectors mate securely. After connecting, secure the FluidLoc seal properly to prevent oil leakage. Finally, route the cable carefully, avoiding sharp bends or contact with high-temperature surfaces. The recommended gap setting for optimal linearity is 1.0 mm (40 mils) (highlighted in red) .
