Bently Nevada 330130-040-01-CN – Extension Cable for 3300 XL Proximity Transducers
The Bently Nevada 330130-040-01-CN is, in many cases, the go-to extension cable for 3300 XL proximity probe systems on critical rotating machinery. It typically provides a 4.0 m extension length, pairing with common 1.0 m probes to form a 5 m system length—exactly what most 3300 XL Proximitor Sensors are calibrated for. One thing I appreciate is the ClickLoc-style secure connectors, which seem to hold up well in high-vibration areas like compressor skids and turbine decks.
Company’s Order Placement Process and Guarantees

Key Features
- 4.0 m length (code “040”): Typically used to achieve a 5 m system length when paired with a 1 m probe.
- Designed for 3300 XL systems: Matches the impedance and capacitance needed for accurate gap and vibration measurements.
- ClickLoc connectors: Secure, vibration-resistant couplings to minimize loosening during operation.
- Robust jacket materials: Industrial-grade cable insulation offers good resistance to oils and typical plant contaminants.
- Option code “-01-CN”: Commonly denotes a standard connection option with a China-market variant; we can verify the exact build for your spares list.
- Passive signal path: Carries the probe’s DC gap and dynamic vibration signal to the Proximitor without external power.
Technical Specifications

| Dimensions & Weight | Length code 040 = 4.0 m (approx. 13.1 ft); compact industrial coax form factor |
| Operating Temperature | Typically aligns with 3300 XL cable ratings; many installs run from approx. -51 to +177 °C (confirm per site approvals) |
| Signal I/O Type | Coaxial transducer line (DC gap + dynamic vibration from probe to Proximitor) |
| Interfaces / Connectors | Bently Nevada ClickLoc-style coax connectors, each end (probe side / Proximitor side) |
| Installation Method | Route from probe to Proximitor; secure with strain relief, observe bend radius, and segregate from high-voltage runs |
Application Fields
From my experience, you’ll see the 330130-040-01-CN used wherever a 3300 XL proximity system is monitoring shaft vibration and position:
- Steam and gas turbines (turbomachinery protection and diagnostics)
- Compressors and expanders in oil & gas processing
- Pumps, motors, and gearboxes in chemical and power plants
- Fans and blowers where continuous vibration trending is required
Advantages & Value
- Proven compatibility: Mates with 3300 XL probes and Proximitor Sensors for correct system length and calibration, reducing setup guesswork.
- Reliable signal integrity: Cable impedance and construction support accurate gap voltage and dynamic signal transmission, which typically improves trend stability.
- Lower downtime risk: ClickLoc connectors help prevent loosening; you might notice fewer nuisance alarms after swaps.
- Spares standardization: Keeping the 4.0 m extension in stock streamlines 5 m system builds in most plants.
- Procurement confidence: Clear build code traceability (-040 length, -01-CN option) helps avoid mismatches in multi-unit fleets.
A maintenance supervisor recently told me their team swapped a third‑party cable for this model and “the bias voltage stabilized immediately.” It’s a small change that, in many cases, prevents hours of troubleshooting.
Installation & Maintenance
- Environment: Route in clean, dry cable trays or conduit; avoid high-heat zones unless specified for your site.
- Bend radius: Maintain a generous bend radius (typically no tighter than about 10× cable OD) to protect the dielectric and shielding.
- Separation: Keep clear of high-voltage and VFD power cables to limit induced noise on the transducer line.
- System length check: Confirm probe + extension length equals the Proximitor’s calibrated system length (commonly 5 m or 9 m) before commissioning.
- Connections: Hand‑tighten ClickLoc connectors until they lock; ensure strain relief near the probe and Proximitor ends.
- Routine care: Periodically inspect for abrasion or chemical attack; clean connectors with appropriate solvent and re‑seat if gap readings drift.
- Firmware/monitoring: If used with rack monitors (e.g., Bently Nevada monitoring systems), keep firmware current and verify channel OK statuses after any cable service.
Quality & Certifications
- Manufacturer quality systems are typically ISO 9001 compliant
- CE compliant; RoHS conformity in most configurations
- Agency or regional variants may apply for “-CN” builds; we can confirm specific file numbers on request
- Standard warranty: 365 days
