Bently Nevada 330103-00-03-10-02-CN – 3300 XL Extension Cable for Proximity Probe Systems

The Bently Nevada 330103-00-03-10-02-CN is a factory-length 3300 XL extension cable designed to link 3300 XL proximity probes to their Proximitor sensors. From my experience, the 330103 family is the go‑to choice when you need a drop‑in, length‑matched cable that preserves your system’s scale factor and linear range without extra calibration. The “-03” build typically denotes a 3 m cable, ideal for compact machines or short runs inside a cabinet. The “CN” suffix usually indicates a China market variant (e.g., China RoHS labeling) with performance consistent with the standard global model.

Company’s Order Placement Process and Guarantees

• Lead time: 1 week if in stock, no more than 1 month at the latest
• Payment terms: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Length‑matched for 3300 XL systems – Helps maintain the calibrated sensitivity and linear range of your proximity measurement loop.
• Compatible with 5 mm and 8 mm 3300 XL probes – Typically used between probe and Proximitor sensor on turbines, compressors, and large motors.
• Robust, shielded coaxial construction – Good noise immunity in high‑EMI industrial environments; stable signal integrity.
• High-temperature fluoropolymer jacket – In many cases specified for harsh areas with oil, vibration, and elevated temperatures.
• CN variant – Appears to include China RoHS identification; electrical performance remains the same as the standard part.
• Drop‑in field replacement – You might notice that swapping to the exact length code simplifies commissioning and avoids re-baselining.

Technical Specifications

Application Fields

Commonly used in vibration and position monitoring on rotating equipment—gas/steam turbines, compressors, pumps, blowers, and large motors. One thing I appreciate is how the correct cable length keeps the proximitor loop within spec, which is critical during outages when time is tight. It’s also a sensible choice for brownfield retrofits where you must match existing probe lengths without touching the sensor calibration.

Advantages & Value

• Reliability – Length‑matched cable assemblies typically eliminate scale-factor drift and reduce commissioning risk.
• Compatibility – Seamless with 3300 XL probes and Proximitor sensors; no adapters in most cases.
• Cost Control – Avoids re‑work and unplanned calibration, which usually saves labor during turnarounds.
• Support – We can help verify length codes against your installed probe/Proximitor part numbers before shipment.

Installation & Maintenance

• Environment – Route in clean, dry conduit or tray where possible; keep away from high‑voltage power cables to reduce EMI.
• Wiring – Confirm the exact length code matches the probe/Proximitor pair; seat keyed connectors fully until positively latched.
• Bend radius – Use gentle bends; avoid tight bends near connectors. In most cases a generous radius extends cable life.
• Grounding/shielding – Maintain shielding continuity end‑to‑end; do not splice unless per OEM guidance.
• Routine checks – Inspect for abrasion or chemical exposure; clean with a lint‑free cloth; verify connector integrity during scheduled outages.
• Calibration – No calibration on the cable itself, but keep the overall probe system baseline and gap settings verified after maintenance.

Quality & Certifications

• RoHS compliant (CN variant typically includes China RoHS labeling)
• CE marking generally applies at the system level; cable is supplied as an OEM spare part
• Manufacturer’s standard quality controls for 3300 XL assemblies
• Warranty: 365 days from our side
