Bently Nevada 330103-00-04-10-12-00 3300 XL 8 mm Proximity Probe

Product Overview

This Bently Nevada 3300 XL 8 mm Proximity Probe is a non-contact sensor that measures shaft vibration and position in rotating machinery. With a metric M10 x 1 thread and a 1.0 meter (3.3 feet) cable, it is built for permanent installation in harsh industrial environments. The probe tip is made of polyphenylene sulfide (PPS), and the case is constructed from AISI 303 or 304 stainless steel, ensuring corrosion resistance and long service life.

Technical Specifications Breakdown

Key parameters for the 330103-00-04-10-12-00 are listed below for quick reference:

Industry Applications

This proximity probe is widely used in turbomachinery, such as steam turbines, compressors, and pumps, where precise shaft vibration and position monitoring are critical. Its robust stainless steel case and PPS tip withstand oil, moisture, and temperature extremes, reducing unplanned downtime.

Installation & Setup Guidance

Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned ends. Maximum cable length between the probe and monitor is 305 meters (1,000 feet). For radial vibration applications, set the gap to approximately -9 Vdc (1.27 mm or 50 mils). Ensure the probe is threaded into a mounting hole with a maximum thread engagement of 15 mm. The probe is designed to seal differential pressure between tip and case, but is not pressure tested before shipment.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage, especially at the connector and cable entry points. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe’s resistance should be measured between center and outer conductors; for a 1.0 m length, the nominal value is 7.59 ± 0.50 Ω. Any significant deviation may indicate cable or connector degradation.

The Evolution of Machine Protection

Industrial rotating machinery has grown more complex, demanding precise, real-time monitoring to prevent catastrophic failures. The Bently Nevada 3300 XL series has long set the standard for proximity probe technology, offering engineers the accuracy and durability needed for critical asset protection. The 330103-00-04-10-12-00 represents a refined iteration of this legacy, designed for seamless integration into modern condition monitoring systems.

Compatibility & Integration

The 330103-00-04-10-12-00 is part of the Bently Nevada 3300 XL system and is compatible with 3300 XL Proximitor sensors and monitors. For intrinsically safe installations, use approved zener barriers per drawing 141092 or galvanic isolators. For non-incendive installations, use barriers per drawing 140979. The probe meets Class I, Zone 0 and Zone 2 hazardous area requirements.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the thread size (M10 x 1), overall length, and cable length. The 330103-00-04-10-12-00 offers a 1.0 m cable with a miniature coaxial ClickLoc connector and FluidLoc cable. Contact AutoDCSTech for availability and lifecycle status before ordering.
