Bently Nevada 330930-060-01-05 NSv Extension Cable

Bently Nevada 330930-060-01-05 Extension Cable

Product Introduction

The Bently Nevada 330930-060-01-05 is a high-quality extension cable specifically designed for the 3300 NSv proximity transducer system. This 6.0-meter (19.7 feet) cable comes equipped with stainless steel armor and an FEP outer jacket, providing superior mechanical protection against abrasion and chemical exposure. Its 75 Ω coaxial design with fluoroethylene propylene (FEP) insulation ensures stable signal transmission even in the most demanding environments. The cable carries Multiple Approvals (Option 05), confirming its compliance with stringent international standards for industrial safety and performance. Gold-plated brass connectors guarantee a secure connection, while the flexible armor allows for easy routing around machinery components. This 3300 NSv extension cable is a critical component for maintaining accurate vibration and position monitoring in turbomachinery.

Technical Specifications

Electrical Characteristics
This extension cable delivers precise electrical performance for reliable measurements. Its typical capacitance is 69.9 pF/m (21.3 pF/ft) , which ensures minimal signal distortion. The DC resistance for the center conductor measures 0.220 Ω/m (0.067 Ω/ft) , while the shield resistance is 0.066 Ω/m (0.020 Ω/ft) . These low-resistance values contribute to excellent signal integrity over the entire cable length. The cable is compatible with field wiring ranging from 0.2 to 1.5 mm² (16 to 24 AWG) . Bently Nevada recommends using a three-conductor shielded triad cable for optimal noise immunity. Furthermore, the maximum field wiring length between the 3300 XL NSv Proximitor Sensor and the monitor should not exceed 305 meters (1,000 feet) to avoid high-frequency signal rolloff.

Construction and Materials
The cable uses a 75 Ω coaxial, fluoroethylene propylene (FEP) insulated design, which provides excellent dielectric properties and thermal stability. The optional armor consists of flexible AISI 302 stainless steel, offering robust protection against physical damage. This armor is available with or without an FEP outer jacket, depending on the specific application requirements. All connectors are made of gold-plated brass, which resists corrosion and ensures low contact resistance. The tensile strength rating is 220 N (50 lb) at multiple points, including the probe case to probe lead, probe lead to extension cable connectors, and probe case to stainless steel armor. This high pull strength prevents accidental disconnection during installation or maintenance activities.

Environmental Ratings
The Bently Nevada 330930-060-01-05 operates reliably across an exceptional temperature range. Its operating and storage temperature spans from -52°C to +177°C (-62°F to +351°F) . This broad tolerance makes it suitable for applications near gas turbines, steam turbines, compressors, and other high-heat rotating equipment. The FEP insulation and jacket maintain their mechanical properties even under continuous thermal stress, ensuring long-term reliability in critical monitoring applications.

Mechanical and Physical Properties

The cable weighs approximately 1.5 kg including the armor, contributing to its robust feel and durability. Its flexible AISI 302 stainless steel armor allows for bending during installation without compromising the internal conductor integrity. The gold-plated brass ClickLoc connectors lock firmly into place, preventing loosening caused by machine vibration. When using this extension cable, ensure that the combined length of the probe cable and this extension cable matches the Proximitor Sensor's total length requirement. This matching is essential for maintaining the correct system calibration and gap settings.

Installation Guidelines

Proper installation ensures accurate and reliable measurements from your 3300 NSv monitoring system. First, verify that the total length of your probe cable plus this 3300 NSv extension cable equals the Proximitor Sensor's specified total length. Next, clean both connector ends thoroughly before mating them to prevent contamination. Apply the recommended gap setting of 1.0 mm (40 mils) for the 3300 NSv probe. The linear range begins at approximately 0.25 mm (10 mils) from the target and extends to 1.75 mm (70 mils). When routing the armored cable, avoid sharp bends that could stress the armor or internal conductors. Secure the cable with appropriate clamps at regular intervals to prevent strain on the connectors. Finally, ensure that the field wiring connections are properly terminated using ferrules for wire sizes 0.25 to 0.75 mm² (18 to 23 AWG) .
