Bently Nevada 330730-080-10-05 Extension Cable

Bently Nevada 330730-080-10-05 3300 XL 11 mm Extension Cable

Product Introduction

The Bently Nevada 330730-080-10-05 is a specialized 3300 XL series extension cable. This 11 mm cable incorporates FluidLoc technology to prevent fluid migration through the cable interior. For instance, many power plants and oil refineries choose this 3300 XL cable for turbine and compressor installations where oil leakage is a critical concern.

This model 330730-080-10-05 offers an 8.0-meter (26.2 feet) length. The FluidLoc option (10) provides a positive seal against oil and other process liquids. Furthermore, the multiple approvals option (05) ensures compliance with international safety standards. This extension cable delivers reliable signal transmission while preventing fluid contamination.

The ClickLoc connectors feature gold-plated brass construction for low resistance. These connectors lock securely into place, preventing accidental disconnection. Additionally, silicone tape is included for extra sealing, though it is not recommended where turbine oil exposure is expected.

Technical Specifications

The Bently Nevada 330730-080-10-05 uses 75Ω triaxial cable with FEP insulation. This construction maintains signal integrity over the full 8.0-meter length. The cable capacitance measures 69.9 pF/m (21.3 pF/ft) typical for consistent system performance.

DC resistance values are precisely specified for this length. The center conductor resistance (RCORE) measures 2.0 Ω ± 0.5 . Meanwhile, the coaxial conductor resistance (RJACKET) is 0.6 Ω ± 0.2 . These tight tolerances ensure accurate signal transmission from the probe to the monitoring system.

The connector material is gold-plated brass for excellent conductivity. The FluidLoc sealing system prevents oil from migrating through the cable's interior. Consequently, this 3300 XL extension cable protects both the machine and the environment from fluid contamination.

FluidLoc Technology Advantages

The FluidLoc option is a key feature of this extension cable. This technology creates a positive seal that blocks oil and other liquids from leaking out of the machine through the cable interior. Therefore, it is particularly valuable for turbine and compressor applications where oil mist or liquid oil is present.

Additionally, the connector protector option provides extra sealing against humidity. While this model does not include the connector protector, silicone tape is supplied as an alternative. However, silicone tape should not be used where the connection will be exposed to turbine oil.

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 various climates. The unarmored cable weighs 45 g/m (0.5 oz/ft), totaling approximately 0.36 kg for the 8.0-meter length. If armored, the weight increases to 140 g/m (1.5 oz/ft).

The 3300 XL system uses ClickLoc connectors throughout. These connectors lock positively and resist vibration-induced loosening. Additionally, the patented CableLoc design provides 330 N (75 lb) pull strength at the probe cable attachment.

Installation Guidelines

Follow these steps to install the Bently Nevada 330730-080-10-05 correctly:

• Cable inspection : Examine the connectors and FluidLoc seals for any damage. Then clean the connector surfaces if necessary.

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

• FluidLoc verification : Ensure the FluidLoc sealing is properly engaged. This prevents oil from migrating through the cable interior.

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

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

For field wiring, use three-conductor shielded triad cable. The recommended wire size is 0.2 to 1.5 mm² (16 to 24 AWG). The maximum field wiring length is 305 meters (1,000 feet) between the Proximitor sensor and the monitor.

Frequently Asked Questions

1. What makes FluidLoc different from a standard extension cable?
FluidLoc creates a positive seal that prevents oil and liquids from leaking through the cable interior. Therefore, it is ideal for turbine and compressor applications where oil contamination is a concern.

2. Is the 330730-080-10-05 compatible with existing 3300 XL probes?
Yes, this Bently Nevada 330730-080-10-05 uses standard ClickLoc connectors. It works with all 3300 XL probes that have the same connector type.

3. What is the total system length with this extension cable?
The 8.0-meter cable adds to your probe length. The 3300 XL system supports total lengths of 5 or 9 meters including the extension cable.

4. Does this cable include a connector protector?
No, this model uses FluidLoc sealing instead. However, silicone tape is provided as an alternative sealing method for the connector area.

5. Can I use silicone tape with this FluidLoc cable?
Yes, silicone tape is supplied for additional connector sealing. However, do not use it where the connection will be exposed to turbine oil.
