Bently Nevada 330104-00-13-10-02-CN – 3300 XL 8 mm High‑Accuracy Proximity Probe for Critical Machinery Monitoring

The Bently Nevada 330104-00-13-10-02-CN is part of the proven 3300 XL 8 mm proximity transducer family, built for reliable, non-contact measurement of shaft vibration and axial position on compressors, turbines, motors, and other rotating assets. From my experience, this probe is a go-to when plants want stable readings in hot, tough environments and consistent performance aligned with API 670 practices.

Company’s Order Placement Process and Guarantees

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

Key Features

• 8 mm probe tip – A robust, general‑purpose diameter that fits standard 3300 XL sleeves and brackets for most rotating equipment.
• Eddy‑current, non-contact sensing – Stable shaft vibration and position measurements without mechanical wear.
• System sensitivity (typical) – When paired with a matching 3300 XL Proximitor sensor, provides −200 mV/mil (≈7.87 mV/µm) with a linear range suitable for machinery protection.
• High temperature capability – Probe and extension assemblies are designed for harsh environments, typically up to 177 °C, which is common in turbines and hot-bearing areas.
• API 670 practice – The 3300 XL system is widely used where API 670 style performance and documentation are expected.
• Interchangeable system lengths – Works with matching 3300 XL extension cables and Proximitor sensors for 5 m, 7 m, or 9 m system lengths (selectable by option code).
• Low-noise, molded cable – Factory-molded lead reduces electrical noise pickup and improves long-term stability.

Application Fields

This probe is widely used on:

• Steam and gas turbines – radial vibration and thrust position
• Compressors and expanders – bearing vibration and differential expansion setups
• Large motors, pumps, and gearboxes – continuous protection and condition monitoring
• Balance-of-plant equipment – where stable, non-contact displacement is required

One thing I appreciate is how predictable the readings are once the initial gap is set around 1.0 mm, especially on 4140 steel targets. You might notice that trending stays clean even in electrically noisy panels, which in many cases reduces nuisance alarms.

Advantages & Value

• Reliability in harsh service – The 3300 XL family is engineered for heat, oil, and vibration typical in turbomachinery areas.
• Compatibility – Matches 3300 XL extension cables and Proximitor sensors, and integrates into API 670 style protection systems and most DCS/PLC analog inputs via the monitor.
• Lifecycle cost savings – Fewer recalibrations and low drift help reduce maintenance touches. Spare part commonality across assets simplifies inventory.
• Technical support – Clear documentation, established install hardware, and easy field replacement shorten turnaround times.

Customer feedback: “Swapping to 3300 XL 8 mm probes stabilized our axial readings on a hot compressor train; the monitors stopped chasing noise.”

Installation & Maintenance

• Mounting – Use dedicated 3300 XL sleeves or brackets. Lock the probe with a jam nut and set the initial gap typically near 1.0 mm (40 mil) unless your monitor strategy requires otherwise.
• Cabinet & wiring – Place the Proximitor sensor in a ventilated panel, away from high‑EMI sources; route probe/extension cables separately from power cables and VFD outputs.
• Environmental – Keep bends gentle and avoid sharp radii; protect leads from abrasion and oil pooling where possible.
• Safety – De‑energize associated monitoring circuits before disconnecting; follow site lockout/tagout procedures.
• Routine checks – Verify gap reading after outages, clean the probe tip if fouling is suspected, and confirm monitor calibration against known displacements. Firmware updates apply to monitors rather than the passive probe.

Quality & Certifications

• CE marking; RoHS compliant; manufactured under ISO 9001 quality systems
• Designed for use in API 670 compliant protection systems (typical)
• Manufacturer’s warranty: 365 days (from our supply)
