Bently Nevada 330104-04-10-10-02-00 3300 XL 8 mm Proximity Probe

Introduction

When unexpected machinery downtime threatens production targets, the Bently Nevada 330104-04-10-10-02-00 3300 XL 8 mm Proximity Probe delivers the precise, non-contact measurement you need. This probe is part of the trusted 3300 XL series, designed for continuous vibration and position monitoring of rotating equipment such as turbines, compressors, and pumps. With its robust construction and proven performance, it helps you detect early signs of mechanical faults before they escalate into costly failures.

Technical Specifications Breakdown

The 330104-04-10-10-02-00 features an unthreaded length of 40 mm and an overall case length of 100 mm, with a total length of 1.0 meter (3.3 feet). It uses a miniature coaxial ClickLoc connector with standard cable for secure and easy installation. The probe tip is made of polyphenylene sulfide (PPS), while the case is AISI 303 or 304 stainless steel (SST), ensuring durability in harsh industrial environments. Nominal probe DC resistance from center conductor to outer conductor is 7.59 ± 0.50 ohms for the 1.0 meter length. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring.

Industry Applications

This proximity probe is ideal for monitoring shaft vibration and axial position in critical rotating machinery. In a steam turbine application, it provides real-time data to the protection system, enabling operators to balance loads and avoid overspeed events. In a centrifugal compressor, the probe's 8 mm sensing face and 1.0 meter cable length allow flexible placement near bearing housings. The 330104-04-10-10-02-00 ensures reliable performance even in high-temperature or high-pressure environments, thanks to its stainless steel case and PPS tip.

Installation & Setup Guidance

For optimal performance, mount the probe with the M10 x 1 thread into a properly tapped hole, ensuring the tip is perpendicular to the target surface. Gap the probe at 1.27 mm (50 mils) from an AISI 4140 steel target for standard calibration. Use the supplied ClickLoc connector to attach the extension cable, and verify that the system includes only 3300 XL 8 mm components to maintain accuracy. Always follow the installation drawing 140979 for non-incendive circuit connections.

Maintenance & Reliability

Regularly inspect the probe cable and connector for signs of wear or damage. Clean the probe tip gently with a soft cloth to remove debris, avoiding solvents that could damage the PPS material. Verify the Viton O-ring seal integrity during scheduled maintenance to prevent moisture ingress. The 330104-04-10-10-02-00 is designed for long service life, reducing replacement frequency and lowering total cost of ownership.

Selection Guide & Purchasing Advice

Before ordering, confirm that your system requires an 8 mm probe with 1.0 meter cable and M10 x 1 thread. The 330104-04-10-10-02-00 does not include agency approvals, so verify if your application needs any certifications.
