Bently Nevada 330930-065-00-05 NSv Extension Cable

Bently Nevada 330930-065-00-05 3300 NSv Extension Cable

Product Introduction

The Bently Nevada 330930-065-00-05 is a high-performance extension cable for the 3300 NSv series. This coaxial cable connects your NSv probe to the Proximitor® sensor for accurate vibration and position monitoring. For instance, many facilities choose this 3300 NSv cable for small turbines, pumps, and compressors where space is limited.

This model 330930-065-00-05 offers a 6.5-meter (21.3 feet) length. The option 00 indicates it comes without stainless steel armor, making it lighter and more flexible. Furthermore, the multiple approvals option (05) ensures compliance with international safety standards. This extension cable delivers consistent performance for the 3300 NSv system.

The cable uses a 75Ω coaxial design with FEP insulation. Gold-plated brass connectors provide excellent conductivity and corrosion resistance. Additionally, the ClickLoc locking mechanism prevents accidental disconnection during operation.

Technical Specifications

The Bently Nevada 330930-065-00-05 features precision electrical characteristics. The center conductor DC resistance measures 0.220 Ω/m (0.067 Ω/ft) . Meanwhile, the shield resistance is 0.066 Ω/m (0.020 Ω/ft) . These values ensure accurate signal transmission over the 6.5-meter length.

The cable capacitance is 69.9 pF/m (21.3 pF/ft) typical. This consistent capacitance maintains signal integrity across the full cable length. Consequently, the system delivers reliable measurements without degradation.

The connector material is gold-plated brass for low contact resistance. This ensures a stable electrical connection throughout the system's life. The tensile strength rating reaches 220 N (50 lb) at all connection points.

System Length Requirements

When using this extension cable, the total system length must match the Proximitor sensor specification. The extension cable length and probe length, when added together, must equal the Proximitor sensor total length. Therefore, verify your probe length before ordering the extension cable.

The 3300 NSv system supports various probe and extension cable combinations. This flexibility allows you to configure the system for your specific installation requirements.

Mechanical and Environmental Ratings

The extension cable operates from -51°C to +177°C (-60°F to +351°F). This broad range supports most industrial applications across diverse climates. The unarmored construction makes the cable lighter and easier to route in confined spaces.

The gold-plated connectors resist corrosion and maintain signal quality. The ClickLoc design ensures a secure connection that withstands vibration. For field wiring, use three-conductor shielded triad cable with a maximum length of 305 meters (1,000 feet) between the Proximitor sensor and the monitor.

Installation Guidelines

Follow these steps to install the Bently Nevada 330930-065-00-05 correctly:

• System verification : Confirm that your probe length plus this 6.5-meter cable equals the Proximitor sensor total length. This ensures proper calibration.

• Cable inspection : Examine the connectors for any damage before installation. Then clean them if necessary.

• Connector mating : Align the connectors carefully and push until they click. Next, pull gently to verify the lock is secure.

• Cable routing : Avoid sharp bends and excessive tension. Maintain a minimum bend radius suitable for coaxial cable.

• Cable securing : Use cable ties every 300 mm to prevent chafing. Do not over-tighten the ties.

For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) wire. With ferrules, use 0.25 to 0.75 mm² (18 to 23 AWG). The maximum field wiring length is 305 meters between the Proximitor sensor and the monitor.

Frequently Asked Questions

1. Is the 330930-065-00-05 compatible with 3300 XL probes?
No, this Bently Nevada 330930-065-00-05 is specifically designed for the 3300 NSv system. It uses a coaxial connector that differs from the 3300 XL triaxial design.

2. Why must the probe and extension cable lengths match the Proximitor total length?
The Proximitor sensor is calibrated for a specific total system length. Therefore, the probe length plus extension cable length must equal the sensor's specified total length for accurate readings.

3. What is the advantage of the unarmored version (option 00)?
The unarmored cable is lighter and more flexible. Therefore, it is easier to route in tight spaces where mechanical protection is not required.

4. Does this cable include a connector protector?
No, this model does not include a connector protector. However, the gold-plated connectors provide good corrosion resistance for most environments.

5. Can I use this cable with armored extension cables?
You should not mix different cable types in the same system. For consistent performance, use the same cable series throughout the installation.
