BENTLY NEVADA 330704-000-100-10-02-00 – Proximity Transducer Extension Cable for 3300/3500 Machinery Monitoring

The BENTLY NEVADA 330704-000-100-10-02-00 is a factory-terminated proximity transducer extension cable used in the 3300/3500 series vibration and position monitoring systems. From my experience, this part is chosen when teams need a dependable, drop-in cable between the eddy-current probe and the Proximitor sensor—especially on critical assets like turbines, compressors, and large pumps. You might notice that the mid-code “100” typically denotes a 10.0 m cable length in Bently Nevada’s build scheme, which makes planning conduit runs and junction box layouts a lot easier.

Our Order Placement Process and Guarantees

Key Features

• Designed for 3300/3500 proximity systems – Ensures signal integrity between the probe and Proximitor sensor in most installations.
• Factory-terminated coaxial construction – Stable impedance and low noise pickup for accurate vibration/position measurements.
• Build-code traceability – The “100” segment typically indicates 10.0 m length, making spares management straightforward.
• Rugged industrial routing – Suited for cable trays, conduit, or cabinet runs found around rotating equipment.
• Drop-in replacement – Typically compatible with existing Bently Nevada probe/Proximitor pairs to reduce outage time.

Technical Specifications

Application Fields

Typically used across rotating machinery where precise shaft vibration or position is monitored:

• Steam and gas turbines, generators, gearboxes
• Compressors (centrifugal/reciprocating), expanders
• Pumps and fans in petrochemical, refining, and power plants
• Balance-of-plant equipment where 3300/3500 monitoring is installed

Advantages & Value

• Reliability you can count on – Stable impedance and shielding for clean signals, which seems to be the difference when chasing intermittent noise.
• Compatibility – Works with Bently Nevada probe/Proximitor chains, reducing configuration effort during turnarounds.
• Lower total cost of downtime – Drop-in replacement typically shortens maintenance windows and avoids rework.
• Traceable build code – Easier stocking and matching lengths across assets, especially when plants standardize on 10 m runs.
• Technical support – We help verify cable lengths, routing advice, and connector matching before you lock in an order.

Installation & Maintenance

• Cabinet and routing – Use clean, dry enclosures; route in conduit or tray away from high-voltage lines to minimize EMI.
• Bend radius – Maintain a gentle bend radius; avoid kinks and sharp edges to preserve coax integrity.
• Connections – Ensure secure, clean terminations; do not overtighten. Verify mating with the correct Proximitor and probe type.
• Grounding – Follow plant grounding standards; avoid ground loops that can introduce noise.
• Routine checks – Inspect for abrasion or crushing, confirm continuity during outages, and re-verify gap readings after any cable replacement.

Quality & Certifications

• CE and RoHS compliance typical for Bently Nevada transducer components
• Manufactured under ISO 9001 quality systems
• Supplier warranty: 365 days from shipment

One thing I appreciate is how consistent the 3300/3500 ecosystem is—once the cable length and connectors are matched, commissioning tends to be straightforward. If you’d like, share the probe and Proximitor part numbers you’re pairing with this 330704-000-100-10-02-00, and I’ll double-check length and compatibility before you place the order.
