330103-00-05-90-02-00 3300 XL 8 mm Proximity Probe | Bently Nevada

Product Overview

The Bently Nevada 330103-00-05-90-02-00 serves as the primary sensor for the 3300 XL 8 mm Proximity Transducer System. This eddy current probe enables non-contact, high-precision measurement of shaft vibration and position in critical rotating machinery. We guarantee this unit as 100% Brand New and Original, providing the exact electrical and mechanical specifications required for OEM machinery protection.

Part Number Breakdown

This specific 330103 configuration provides an extended cable length for direct connection to Proximitors® without intermediate extension cables in certain setups:

Technical Specifications

The probe functions as a high-frequency tuned circuit, delivering a voltage output proportional to the distance from the target.

• Probe Diameter: 8 mm

• Case Material: AISI 303 or 304 Stainless Steel (SST)

• Tip Material: Polyphenylene sulfide (PPS)

• Total Length: 9.0 Meters (Integral Cable)

• Operating Temperature: -35 °C to +177 °C (-31 °F to +350 °F)

• Linear Range: 2.0 mm (80 mils) typical

• Scale Factor: 7.87 V/mm (200 mV/mil) when properly matched

• Condition: 100% Brand New Original

Engineering Advantages

• Extended 9.0m Reach: The 9.0-meter integral cable eliminates the need for an extension cable in many installations. By removing the mid-point connection, you reduce the potential for signal contamination and mechanical failure at the junction.

• Deep-Reach Mounting: The 5.0-inch (127 mm) case length allows the probe to penetrate thick bearing housings or outer machine casings, ensuring the tip reaches the target shaft without requiring custom mounting sleeves.

• ClickLoc™ Connection Stability: The ClickLoc™ connector features a self-locking mechanism. It prevents the cable from backing out under high-vibration conditions, ensuring constant electrical contact and reducing the risk of "NOT OK" system status trips.

• Extreme Environment Durability: The PPS tip and stainless steel case body resist moisture, oils, and chemical lubricants. This robust construction ensures long-term measurement stability inside hot, fluid-rich machine environments.

FAQs

Can I use this 9.0m probe with an extension cable?

You should only use this probe with a Proximitor® calibrated for a 9.0-meter system. If you add an extension cable to this 9.0m probe, the total system length will exceed the standard 3300 XL calibration (usually 5m or 9m), resulting in significant measurement errors. This probe typically connects directly to the Proximitor®.

Does this probe require a special mounting bracket?

No, it uses standard M10x1 threads (or 3/8-24 depending on specific series options). The 5.0-inch case length provides ample threading for standard brackets, though we recommend using the included locknuts to secure the final gap position.

How do I confirm the probe is "Brand New"?

Every unit we ship arrives in its original factory packaging with a clear Bently Nevada serial number. The factory seal and the pristine condition of the gold-plated ClickLoc™ connector and PPS tip confirm its 100% Brand New status.

What is the correct gap voltage for installation?

For most 3300 XL 8mm systems, setting the probe to -10.0 VDC (the center of the linear range) provides the best performance. Always use a calibrated Digital Multimeter (DVM) to verify the gap during the installation process.
