Bently Nevada 330130-080-13-CN – 3300 XL Extension Cable for Proximity Transducer Systems

The Bently Nevada 330130-080-13-CN is an 8.0 m 3300 XL extension cable designed to connect proximity probes to their Proximitor sensors in rotating machinery monitoring. It’s built for stable signal transmission in electrically noisy, high-vibration environments—typical of turbines, compressors, pumps, and large motors. One thing I appreciate is how these molded connectors reduce installation errors and keep the system repeatable over time.

You might notice this part sometimes gets listed as a “power module.” It isn’t—this model is the 3300 XL extension cable series (330130), used to complete the specified system length for accurate vibration and position measurements.

• 8.0 m cable length – Helps you achieve the required system length between probe and Proximitor sensor.

• 3300 XL compatibility – Works with 3300 XL 5 mm/8 mm proximity probes and matching Proximitor sensors used in 3300/3500 monitoring systems.

• Robust molded connectors – Factory-terminated, keyed connectors typically reduce installation time and prevent polarity mistakes.

• Stable signal integrity – Designed to carry both dynamic vibration and DC gap signals with strong immunity to EMI in industrial cabinets.

• Field-proven durability – Jacket and strain-relief design suited for routed conduit and cabinet applications in most plants.

• Option code “-13-CN” – Typically denotes a specific connector/boot configuration and regional packaging; ideal when you need consistency across sites.

From my experience, this model shows up in condition monitoring systems across:

• Steam and gas turbines (bearing and shaft relative vibration monitoring)

• Compressors and expanders (radial/axial position and vibration)

• Pumps and fans (unbalance, rub detection, and shaft position trending)

• Large AC motors and generators (bearing condition and shaft vibration)

• Refining, petrochem, power generation—anywhere 3300/3500 racks are deployed

• Assured compatibility – Designed to work seamlessly with Bently Nevada 3300 XL transducer components, which typically avoids recalibration surprises.

• Lower installation risk – Pre-terminated connectors cut down wiring mistakes and rework time.

• Signal reliability – Stable cable impedance and shielding help maintain accurate gap and vibration readings.

• Lifecycle support – Easy to stock, easy to replace; practical for plants standardizing on Bently Nevada hardware.

A maintenance lead at a petrochem site told me they swapped in a 330130 8 m cable to match their probe length, and the noise floor immediately settled—no more intermittent spikes during startup. That tends to be the case when the total system length is configured correctly.

• Cabinet routing – Keep the cable away from high-voltage lines and VFD outputs; use segregated conduits when possible.

• Bend radius – Avoid tight bends; a generous bend radius typically prolongs cable life and preserves signal fidelity.

• Grounding/shielding – Follow Bently Nevada grounding practices; don’t introduce floating shields or ad-hoc splices.

• Connector care – Seat connectors fully until you feel the positive engagement. If needed, clean mating ends with isopropyl alcohol—no abrasives.

• System length check – Match probe + extension cable length to the Proximitor sensor’s specified length. Mixing lengths can affect sensitivity and bias voltage.

• Routine checks – During shutdowns, visually inspect cable runs for abrasion, crushed sections, or loose supports; replace if insulation is compromised.

• Manufactured to Bently Nevada quality standards (ISO 9001 production environment is typical for these components)

• CE and RoHS compliance in most cases; regional approvals may apply with “CN” packaging

• Manufacturer’s standard warranty applies

• 3300 XL 5 mm/8 mm proximity probes (various lengths and tip styles)

• 3300 XL Proximitor sensors matched to total system length

• 3500 monitoring racks and channel cards for vibration and position

If you need confirmation on the “-13-CN” option specifics for your site standard, share your current probe and Proximitor model codes. I can quickly verify the length matching and connector options so you get a drop-in fit.
