Bently Nevada 330703-000-070-10-01-EN – Proximity Transducer Extension Cable for 3300 XL Systems

The Bently Nevada 330703-000-070-10-01-EN appears to be configured as a factory-built extension cable for the 3300 XL proximity transducer system. In many cases, the “-070” option denotes a 7.0 m cable length, which is commonly paired with 3300 XL probes and Proximitor Sensors to achieve a correct total transducer system length. From my experience, sticking with OEM-coded lengths keeps the 200 mV/mil (7.87 mV/µm) calibration consistent and avoids unexpected bias or linearity drift.

If you’re maintaining critical rotating assets—compressors, turbines, large motors—this cable drops straight in with minimal fuss. One thing I appreciate is how these assemblies are designed to survive tough routing inside machinery guards and cabinets without introducing noise into the displacement signal. You might notice that change-outs during turnarounds become much faster when you keep length and connector options consistent with your installed base.

Key Features

• 3300 XL compatibility – Built to interconnect the probe and Proximitor Sensor in the 3300 XL proximity system.
• 7.0 m configuration – The “-070” option typically denotes a 7 m cable length, helping maintain correct total system length.
• Low-noise, shielded construction – Designed to preserve proximity signal integrity in electrically noisy environments.
• Rugged build for plant use – Suitable for routing through conduit or trays; resists oil mist and common industrial contaminants.
• Drop-in replacement – Keeps calibration consistent when replacing like-for-like assemblies, saving setup time.
• Service-friendly connectors – Factory-terminated mini‑coax style ends that mate directly with probe and Proximitor Sensor.

Technical Specifications

Application Fields

Typically used across rotating machinery monitoring where stable shaft displacement and vibration measurements matter:

• Oil & gas compressors, pumps, and turboexpanders
• Steam and gas turbines in power generation
• Large motors, gearboxes, and critical fans in heavy industry
• Refining and petrochemical process equipment
• Pulp & paper and mining conveyors/drive trains

Advantages & Value for Procurement

• Form-fit-function match – Keeps your 3300 XL loops within spec, avoiding re-baselining during maintenance.
• Reliability in harsh areas – Shielding and ruggedization reduce nuisance noise and unplanned callouts.
• Lower lifecycle cost – Faster swap-outs mean shorter downtime windows; fewer tuning headaches.
• Compatibility assurance – Plays well with existing probes and Proximitor Sensors configured to standard 5/7/9 m lengths.
• Technical support – Help verifying option codes and length matching before shipment to prevent misorders.

Installation & Maintenance

• Environment – Route in metallic conduit or tray where possible; keep distance from VFD power cables to limit EMI.
• Bend radius – Maintain a gentle bend radius; avoid sharp edges and pinch points at machine covers.
• Grounding & shielding – Follow 3300 XL grounding practices; terminate shields as per the Proximitor Sensor guidance.
• Length integrity – Match the cable length to your probe so the total system length remains 5, 7, or 9 m (typical for 3300 XL).
• Routine checks – During outages, inspect connectors for looseness or corrosion and wipe down cable runs; no field calibration required if part length matches the original.
• Firmware/monitoring – When used with rack monitors, apply firmware updates on the monitoring system as recommended; the passive cable itself needs no updates.

Quality & Certifications

• Manufactured under ISO 9001 quality systems (typical for Bently Nevada production)
• RoHS compliance and CE marking commonly applied for the 3300 XL family
• UL/CSA and regional approvals may apply depending on system configuration
• Warranty: 365 days (repair/replace policy)

Supporting Components You May Need

• 3300 XL Proximity Probes (5 mm or 8 mm tip) – pair with the same total system length.
• 3300 XL Proximitor Sensor – matches the probe/cable set; ensures proper 200 mV/mil scaling.
• Mounting hardware and junction boxes – for clean routing and protection near the machine.

A quick note from a maintenance lead who recently swapped one of these: “We kept the exact length and connector options. The channel came back in range immediately—no extra tuning. Whole job took under an hour.” That mirrors what we typically see when installs follow the original BOM.
