Bently Nevada 330103-00-07-50-02-00 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-07-50-02-00 are listed below for quick reference:

Industry Applications

This proximity probe is engineered for continuous monitoring of radial vibration and axial position in turbines, compressors, pumps, and other rotating equipment. Its 2 mm linear range and -9 Vdc recommended gap setting provide precise, repeatable measurements for predictive maintenance programs. The 5.0 meter cable length is specifically matched for use with the 5 meter Proximitor sensor, ensuring signal integrity over the entire run.

Installation & Setup Guidance

When installing the 330103-00-07-50-02-00, ensure the probe tip is clean and free of debris. Use the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration applications. Field wiring should be 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable, with a maximum length of 305 meters (1,000 feet) between the Proximitor sensor and the monitor. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal.

Maintenance & Reliability

Periodically inspect the probe cable and connector for signs of wear or damage. The Viton® O-ring seal is designed to maintain differential pressure between the tip and case, but probes are not pressure tested prior to shipment. For applications requiring pressure seal verification, contact the custom design department. The probe operates reliably in relative humidity up to 93% (per IEC 68-2-3) with less than 3% change in Average Scale Factor.

Precision Vibration Monitoring with the Bently Nevada 330103-00-07-50-02-00

In rotating machinery, accurate proximity measurement is critical for preventing catastrophic failures. The Bently Nevada 330103-00-07-50-02-00 is a 3300 XL 8 mm Proximity Probe designed for reliable shaft vibration and position monitoring in demanding industrial environments. This metric probe features an M10 x 1 thread, a 70 mm overall case length, and a 5.0 meter cable, making it a direct fit for many standard installations. Its robust construction — with a polyphenylene sulfide (PPS) tip and AISI 303/304 stainless steel case — ensures long-term stability even under harsh conditions.

Compatibility & Integration

This probe is designed exclusively for use with the 5 meter Proximitor sensor. It supports intrinsically safe installations when paired with approved zener barriers (per drawing 141092) or galvanic isolators, achieving Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga ratings. For non-incendive installations (per drawing 140979), it meets Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc requirements. Always verify compatibility with your existing monitoring system before ordering.

Selection Guide & Purchasing Advice

Choosing the correct proximity probe requires matching cable length, thread size, and connector type to your application. The 330103-00-07-50-02-00 offers a 5.0 meter cable, M10 x 1 metric thread, and a miniature coaxial ClickLoc connector. Before purchasing, confirm that your Proximitor sensor is rated for 5 meter cable operation. AutoDCSTech stocks this exact model and can assist with lifecycle status and availability.
