Bently Nevada 330104-00-04-10-02-RU – 4 m Extension Cable for 3300 XL 8 mm Proximity Transducer Systems

The Bently Nevada 330104-00-04-10-02-RU is, in practical terms, the factory-terminated extension cable used to connect a 3300 XL 8 mm proximity probe to its Proximitor Sensor. From my experience, this part is the quiet workhorse in vibration and position monitoring loops—when it’s right, your gap voltage is steady and your data quality is predictable. The “-04” code typically denotes a 4-meter cable length, “-00” indicates the standard (non-armored) variant, and the “RU” suffix usually points to a Russian-language documentation pack; the hardware itself is the same globally.

Key Features

• Designed for 3300 XL 8 mm systems: Typically used between a 330103 8 mm probe and a 3300 XL Proximitor Sensor for turbine, compressor, and pump monitoring.
• 4 m cable length (-04): Commonly paired with a 1 m probe to make a 5 m system length, which many sites standardize on.
• Factory-terminated connectors: You might notice the ClickLoc-style terminations that make field replacement clean and consistent, reducing noise from poor connections.
• Stable signal transmission: Coax construction intended for low-noise eddy-current transducer signals, which, in many cases, prevents intermittent readings.
• Rugged jacket materials: Typically FEP or equivalent; suitable for industrial routing in cabinets, tray, or conduit.
• Interchangeable within the 3300 XL family: One thing I appreciate is the drop-in compatibility that keeps spares simple and avoids re-engineering.

Technical Specifications

Application Fields

This cable sits at the heart of rotating machinery monitoring. Typical deployments include steam and gas turbines, centrifugal compressors, large motors, gearboxes, and process pumps. You get consistent gap voltage and clean vibration/position signals when the probe–cable–Proximitor chain is matched. A maintenance lead at a gas compression station told us they swapped only the 330104 cable during a turnaround and immediately recovered a stable 200 mV/mil response on their radial probes—no sensor change needed.

Advantages & Value

• Reliability in harsh environments: The 3300 XL ecosystem is known for stable readings over long runs and temperature swings.
• Compatibility and simplicity: Matches 330103 probes and 3300 XL Proximitor Sensors; fewer variables during troubleshooting.
• Cost-effective maintenance: In many cases, replacing a damaged cable restores performance without touching the probe or proximitor.
• Traceable supply: Genuine parts help avoid calibration drift and connector mismatch issues that often appear with generic cables.

Installation & Maintenance

• Cabinet and routing: Use ventilated panels; route in tray or conduit away from high-frequency drives and power cables. Good segregation typically reduces noise pickup.
• Bend radius: Keep a gentle bend—about 10x the cable diameter is a practical rule. Sharp bends can degrade shielding and signal quality.
• Connector care: Seat ClickLoc connectors fully; finger-tight plus a small turn is usually adequate. Do not overtighten.
• Wiring checks: Verify continuity, insulation, and overall loop length (probe + cable) against your monitoring plan (e.g., 5 m systems are common).
• Routine maintenance: During outages, inspect jacket condition, connectors, and strain reliefs; clean with non-aggressive solvents and validate gap voltage at the proximitor.
• Firmware and calibration notes: While the cable is passive, it’s good practice to log proximitor calibration checks after any cable replacement.
• Safety: De-energize associated monitoring channels when handling connectors; avoid routing near hot lines or rotating parts without protective conduit.

Quality & Certifications

• Certifications: Typically CE-marked within the 3300 XL family; RoHS alignment is common for current-production components; manufacturer operates under ISO 9001 quality systems.
• Warranty: 365 days (our supply guarantee).

Compatible/Supporting Components (for convenient spares planning)

• 330103 8 mm Proximity Probe (typical pairing; various lengths and thread options)
• 3300 XL Proximitor Sensor (8 mm system; panel-mounted, standard ranges)
• Mounting hardware and probe extension accessories as required by your machine layout

If you’re standardizing on 5 m systems, this exact “-04” cable length usually matches a 1 m probe. If your site runs 9 m systems, consider ordering longer cables accordingly. It seems minor, but having consistent total lengths across trains keeps your calibration data tidy and comparable.
