Description
The Bently Nevada 330103-00-05-10-02-00 is a high-performance 5mm/8mm proximity sensor designed for non-contacting vibration and displacement measurements. It forms a critical part of the 3300 XL series, converting the mechanical gap between the probe tip and the target shaft into a proportional voltage signal.
Engineers typically deploy this specific Proximitor in critical rotating machinery—such as steam turbines and centrifugal compressors—to track radial vibration and axial thrust. We provide these units to global maintenance teams to ensure machinery protection systems remain calibrated and active, preventing catastrophic equipment failure.

How does this specific sensor configuration impact your installation? In field deployments at power generation facilities, we have noted that the 35mm DIN rail mount (-05 option) is the industry standard for clean integration into marshalling cabinets.
The ClickLoc connector on the 0.5-meter pigtail cable is designed to be “finger-tight.” A common mistake in the field is using pliers to tighten these gold-plated connectors—don’t do it. Over-tightening can strip the threads or damage the internal pins, leading to intermittent signal “spikes” that can cause false trips.
Well, technically this Proximitor is designed for 8mm probes, but it is physically compatible with 5mm probes as well, since they share the same electrical characteristics—though you should always verify the scale factor in your 3500 rack configuration software after a swap.
In my experience, the most critical step during commissioning is the “Gap” voltage check. You should be looking for a static voltage of approximately -10 V DC when the shaft is at its nominal center. If you see -2 V or -18 V, your probe is either too close or too far, and the sensor will be operating outside its linear range.
Global Trade & Logistics Optimization
Moving specialized vibration sensors across borders requires a high level of logistical precision to avoid customs bottlenecks.
Export Compliance & Documentation
We classify this hardware under HS Code 9031.80.80. Since these sensors are used in power generation and oil/gas, they are subject to routine “End-Use” verification. We handle the generation of all necessary export documents, including the Commercial Invoice, Packing List, and Certificate of Conformance (CoC), ensuring the origin is clearly stated as USA or Mexico to satisfy regional trade agreements.
Shipping & Transit
- Packaging: Every Proximitor is shipped in an ESD-shielded bag to protect the internal oscillator circuitry from static discharge.
- Air Freight: We recommend DHL Express for all sensor shipments. Because they are lightweight and high-value, air freight is the most cost-effective way to ensure they aren’t subjected to the vibrations and temperature extremes of ocean transit.
- Incoterms: Standard delivery is FCA (Free Carrier) or CPT (Carriage Paid To).
Trade Finance
For international procurement, we accept Telegraphic Transfer (T/T). For emergency plant outages, we can expedite the release of goods upon receipt of a confirmed bank SWIFT copy to get your machinery back online as fast as possible.
Frequently Asked Questions
Is the 330103-00-05-10-02-00 interchangeable with older 3300 sensors?
Yes, the 3300 XL series is generally backward compatible with the older non-XL 3300 5mm and 8mm probes. However, you must ensure the total system length (Probe + Extension Cable) matches the Proximitor’s calibration (in this case, 5 meters or 9 meters total).
What does the “10” agency approval mean for my site?
The -10 option provides multiple approvals, including ATEX/IECEx for Zone 0 and Zone 1. This means the unit is safe for use in explosive atmospheres when used with the appropriate zener barriers or galvanic isolators.
Does this unit require a separate power supply?
The Proximitor is powered by the -24 V DC supply typically provided by the Bently Nevada 3500 monitor rack or an external industrial power supply. It does not plug directly into AC mains.
