BENTLY NEVADA 330105-02-12-15-02-05 – Extension Cable for 3300 XL Proximity Transducer Systems

The BENTLY NEVADA 330105-02-12-15-02-05 is a factory-terminated extension cable for 3300 XL proximity probe systems. In many cases it’s the piece that quietly determines whether your shaft vibration and position measurements stay stable or drift. From my experience, this series is chosen for its signal integrity over long runs, robust jacket options, and reliable field connectors that stand up to real plant conditions.

Our Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Purpose-built for 3300 XL systems: Matches the probe and Proximitor sensor to maintain overall system accuracy and linearity.
• Impedance-controlled coax design: Typically 75 Ω to preserve the eddy-current signal integrity and reduce noise pickup.
• Rugged jacket and armor options: The option set on this code usually denotes tougher mechanical protection for abrasive or high-traffic cable runs.
• Factory-terminated connectors: Consistent contact resistance and repeatable performance; you avoid field-termination variability.
• Chemical and oil resistance: Cable materials are engineered for rotating equipment environments in refineries, power plants, and paper mills.
• Drop-in interchangeability: Works with 3300 XL 5 mm and 8 mm proximity probes and their matched Proximitor sensors.

Technical Specifications

Application Fields

You’ll typically find the 330105 cable in critical machinery protection loops where stable displacement and vibration readings are non‑negotiable:

• Steam and gas turbines – shaft relative vibration and axial position
• Compressors and expanders – radial vibration monitoring
• Pumps, fans, blowers – trendable displacement for predictive maintenance
• Gearboxes – casing and shaft condition monitoring in refineries and power plants

One thing I appreciate is how consistent readings stay over time when the cable routing is done right. A maintenance lead at a gas plant told me they moved to the armored option of this series after conduit abrasion issues, and nuisance trips dropped off within a week.

Advantages & Value

• Reliability: Stable impedance and robust terminations help reduce drift and intermittent faults.
• Compatibility: Designed to pair with 3300 XL probes and Proximitor sensors without recalibration headaches.
• Lifecycle savings: Less troubleshooting time on wiring; fewer unplanned shutdowns from cable damage.
• Supportability: Widely used across industries, spares are typically easier to source and replace quickly.

Installation & Maintenance

• Cabinet & routing: Use grounded metallic trays or conduits; keep away from high-voltage runs where possible.
• Bend radius: Avoid tight bends; a gentle radius helps maintain impedance and prolongs cable life.
• Connectors: Hand-tighten to the manufacturer’s spec; check O-rings and threads for cleanliness.
• Ventilation: In junction boxes, allow airflow and avoid pooling of oil/condensate around connectors.
• Periodic checks: Inspect armor/jacket for abrasion; verify signal stability during scheduled outages.
• Calibration practice: When replacing a cable, verify system length settings and gap voltage at the Proximitor to confirm linearity.

Quality & Certifications

• Manufactured under ISO 9001 quality systems (typical for this series)
• CE and RoHS compliance commonly applicable to 3300 XL transducer components
• Manufacturer’s standard quality controls for industrial rotating machinery environments
• Supplied with a 365‑day warranty from our side

Recommended Companion Components

• 3300 XL 5 mm Proximity Probes (e.g., 330103 series): For tight mounting spaces and small targets.
• 3300 XL 8 mm Proximity Probes (e.g., 330106 series): General-purpose shaft vibration and position measurements.
• 3300 XL Proximitor Sensors: Matched drivers to complete the probe–cable–driver transducer chain.

If you’re standardizing spares, this cable code seems to strike a good balance between protection and routing flexibility. You might notice that replacing like-for-like within the 3300 XL family typically avoids any re-baselining of your trends.
