Bently Nevada 330190-040-00-00 – Extension Cable for 3300 XL Proximity Transducer Systems

The Bently Nevada 330190-040-00-00 is a factory-terminated extension cable used to connect 3300 XL proximity probes to their Proximitor sensors. From my experience, this -040 code typically indicates a 4.0 m cable, which pairs with a 1.0 m probe to achieve a 5 m calibrated system length—exactly what many API 670-driven installations still standardize on. If you’re replacing cables during a reroute or panel relocation, this model helps you maintain the original transducer system length and avoid recalibration surprises.

Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: typically 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express Options: FedEx, UPS, DHL

Key Features

• Calibrated Length Integrity: The -040 (≈4.0 m) extension helps maintain a 5 m system when combined with a 1.0 m probe—handy during maintenance swaps.
• OEM-Compatible Connectivity: Uses the standard Bently Nevada coax connection for 3300 XL proximity probes and Proximitor sensors, so no adapters in most cases.
• Signal Fidelity: Shielded coaxial construction preserves the eddy-current probe signal over the run, reducing noise pickup in electrically busy cabinets.
• Rugged Jacket: Industrial-grade outer jacket that typically resists oils and abrasion; suited for cabinet routing and machinery skid environments.
• Field-Friendly Replacement: Pre-terminated ends save time; you can swap like-for-like without reworking connectors.

Technical Specifications

Application Fields

This cable is used across rotating machinery condition monitoring setups—compressors, gas/steam turbines, motors, pumps, and gearboxes. In many cases, teams choose the 4.0 m extension to keep system length consistent after moving Proximitor enclosures to cooler or more accessible panels on skids in oil & gas, power generation, petrochemical, and pulp & paper sites.

Advantages & Value

• Reliability: Stable signal over the specified length; less drift when the total system length matches the original calibration.
• Compatibility: Designed for 3300 XL proximity probes and Proximitor sensors; reduces mixing of non-standard cables.
• Cost-Saving Fit: A straight swap typically avoids re-baselining the transducer calibration, saving field time.
• Support: We help cross-check system length codes (-040 with 1.0 m probe, etc.) so your monitoring channels stay within specification.

Installation & Maintenance

• Cabinet & Routing: Use clean cable trays or ducts; keep away from VFD cables and high-voltage lines. Maintain a bend radius greater than 10× the cable OD.
• Grounding & Shielding: Follow Bently Nevada guidelines; avoid creating ground loops. Typically, the Proximitor end is the reference.
• Connector Care: Do not overtighten; finger-tight plus a slight snug is usually enough. Keep connectors clean and dry; wipe with isopropyl alcohol if needed.
• System Length Check: If you change cable length, confirm the combined probe + cable length matches your Proximitor’s calibration (5 m, 7 m, 9 m system). This prevents sensitivity errors.
• Routine Inspection: Every shutdown, look for jacket damage, kinks, or crushed sections; replace if any deformation is found to avoid intermittent signal loss.

Quality & Certifications

• Certifications: Typically CE and RoHS compliant; manufactured under ISO 9001 quality systems.
• Warranty: 365-day warranty coverage as stated above.

You might notice that maintenance teams often keep a few -040 cables in the spares bin. One thing I appreciate is how predictable the swap is—if the probe length is known, this cable keeps the channel’s calibration right where it should be.
