330130-075-01-00 Bently Nevada 3300 XL Extension Cable | Armored 7.5 m

330130-075-01-00 Bently Nevada 3300 XL Armored Extension Cable

The 330130-075-01-00 is a Bently Nevada 3300 XL proximity system extension cable. It connects a compatible proximity probe to its Proximitor Sensor.

This configuration provides 7.5 meters of extension cable with an armored construction. It supports signal transmission in machinery installations that require additional cable protection and routing flexibility.

The cable uses corrosion-resistant, gold-plated ClickLoc connectors. Its electrical characteristics support compatible 3300-series 5 mm, 3300 8 mm, and 3300 XL 8 mm proximity measurement systems.

Electrical Specifications | Extension Cable Data

System performance note: The extension cable does not independently determine the measurement range, sensitivity, or frequency response. Those values depend on the complete probe, cable, Proximitor Sensor, monitor, target, and wiring configuration.

System Compatibility | Probe and Proximitor Sensor

The compatible Proximitor Sensor input accepts a non-contacting 3300-series 5 mm, 3300 8 mm, or 3300 XL 8 mm proximity probe and extension cable system.

Do not select an extension cable by length alone. The probe, extension cable, and Proximitor Sensor must form a compatible measurement chain.

Armored Cable | Installation Advantages

• Mechanical protection: The armored construction provides additional protection during cable routing and machinery installation.
• ClickLoc connection: Gold-plated connectors support reliable electrical connection when properly seated.
• Longer routing allowance: The 7.5 m length supports installations where the probe and sensor cannot sit close together.
• System integration: Use with compatible Bently Nevada proximity probes and Proximitor Sensors.

Armor does not eliminate the need for correct cable support. Avoid crushing, sharp bends, abrasion, and connector strain.

Installation and Commissioning Checklist

• Confirm the extension cable part number and required cable length.
• Inspect both ClickLoc connectors before mating.
• Route the armored cable away from moving components and high-temperature surfaces.
• Maintain suitable cable support and avoid excessive bending or pulling.
• Check connector engagement and protect the connection against the actual site environment.
• Verify the probe, extension cable, and Proximitor Sensor combination against the manufacturer's system documentation.
• Confirm the monitor receives a stable signal after commissioning.

Connector protection: Each 3300 XL extension cable includes silicone tape for use in place of connector protectors. The manufacturer does not recommend silicone tape where turbine oil may contact the probe-to-extension connection.

Selection Comparison | Armored Cable or FluidLoc

Compare the requested armored cable with the following listed alternative.

Technical recommendation: Choose the armored 7.5 m cable when the installation needs its longer reach and additional mechanical protection. Consider the linked FluidLoc alternative when its shorter length suits the route and the application requires FluidLoc cable construction.

FluidLoc helps prevent oil and other liquids from migrating through the cable interior. Confirm the specific cable's connector arrangement and suitability for the process environment before ordering.

Typical Equipment and Applications

• Steam and gas turbines: Connect shaft proximity probes to monitoring electronics.
• Industrial compressors: Support vibration and shaft-position measurement circuits.
• Centrifugal pumps: Extend proximity probe connections to monitoring equipment.
• Rotating machinery protection: Connect compatible probes to Bently Nevada Proximitor Sensors.
• Maintenance installations: Replace damaged or incorrectly sized extension cables within an established monitoring loop.

Global PLC Spare HUB's Insight | Signal Diagnostics

Extension cable faults can affect signal stability and measurement reliability. Inspect the cable and its connectors before changing monitor settings.

Field example: A machinery channel becomes intermittent after maintenance. An engineer can inspect the extension connectors and cable routing first. The engineer can then check conductor resistance and confirm the cable length against the original configuration. These checks help distinguish a connection problem from a probe or monitor fault.

Use approved test procedures. Do not disconnect or test a live machinery protection loop unless site procedures permit it.

Environmental and System Considerations

• Humidity: The stated 3300 XL system specification reports less than 3% average scale-factor change after testing at 93% relative humidity for up to 56 days.
• Pressure: Probe pressure sealing uses a Viton® O-ring. The probe is not pressure-tested before shipment.
• Hazardous locations: This cable's approval option is 00. Verify the approval requirements for the complete installed loop.
• Signal performance: The supplied linear-range specification applies to a complete 3300 XL 8 mm system under stated test conditions. It does not describe the extension cable alone.

Packaging, Warranty, and Shipping

• Condition: New and original in factory packing, as specified for this listing.
• Packaging contents: Extension cable assembly with the specified armored configuration. Confirm included connector-protection accessories with the order.
• Warranty: 12 months, subject to the seller's written warranty terms.
• Shipping carriers: FedEx, UPS, and DHL.
• Dispatch estimate: 24–48 hours after order confirmation, subject to stock and processing.
• Order assistance: Contact Global PLC Spare HUB to verify cable length, connector configuration, and system compatibility.

Frequently Asked Questions

1. How can I confirm that 7.5 meters is the correct extension length?

Measure the planned route between the probe and Proximitor Sensor. Include routing allowances and service loops. Then confirm the complete probe-and-cable system length against the manufacturer's configuration requirements.

2. Does the armored cable change the probe's measurement calibration?

The armor primarily changes the cable's mechanical construction. However, the complete system must use a compatible cable type and length. Confirm the system configuration and calibration after replacement.

3. What resistance values should I expect when checking this cable?

The supplied nominal values are 1.65 ± 0.25 Ω for center-conductor continuity and 0.49 ± 0.10 Ω for outer-conductor continuity over 7.5 meters. Use suitable test equipment and approved isolation procedures.

4. Can I use this extension cable with a different Bently Nevada probe family?

Compatibility depends on the probe, cable, and Proximitor Sensor combination. The listed input supports specified 3300-series 5 mm, 3300 8 mm, and 3300 XL 8 mm systems. Verify the exact installed components before substitution.

5. When should I choose FluidLoc instead of armored cable?

Choose based on the installation's primary constraint. Armor adds mechanical protection. FluidLoc addresses liquid migration through the cable interior. Compare cable length, connector options, routing conditions, and exposure to oil before deciding.
