Bently Nevada 330104-00-10-05-01-BR 3300 XL 8 mm Proximity Probe, Metric

Introduction: Precision Vibration Monitoring for Critical Machinery

When unplanned downtime threatens production targets, the Bently Nevada 330104-00-10-05-01-BR 3300 XL 8 mm proximity probe delivers the accurate displacement measurements needed for early fault detection. This metric-threaded probe is engineered for radial vibration and position monitoring in rotating equipment such as turbines, compressors, and pumps. Its robust design helps maintenance teams identify bearing wear, shaft misalignment, and imbalance before they cause catastrophic failures.

Technical Specifications Overview

The 330104-00-10-05-01-BR offers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target and extending to 2.3 mm (90 mils). The recommended gap setting for radial vibration is -9 Vdc, corresponding to roughly 1.27 mm (50 mils). Nominal probe DC resistance (RPROBE) is 7.45 ± 0.50 ohms for the 0.5-meter cable length. The probe case material is AISI 303 or 304 stainless steel, and the probe tip is made of polyphenylene sulfide (PPS). Thread specification is M10x1 with a maximum thread engagement of 15 mm. Operating and storage temperature range for the standard probe is -52°C to +177°C (-62°F to +350°F).

Industry Applications: Solving Vibration and Position Challenges

In petrochemical plants, the 330104-00-10-05-01-BR monitors shaft vibration in large centrifugal compressors. Its 2 mm linear range captures both normal operating conditions and developing faults. For power generation, this probe tracks rotor position in steam turbines, enabling operators to adjust load while avoiding contact between rotating and stationary parts. The PPS tip resists chemical exposure common in these environments, while the stainless steel case withstands mechanical stress.

Installation and Setup Guidance

Proper installation begins with verifying the M10x1 thread engagement does not exceed 15 mm. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a three-conductor shielded triad cable and tinned ends. The maximum cable length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Set the initial gap to -9 Vdc for radial vibration applications. Ensure the target surface is clean and free of runout to achieve the specified linear range from 0.25 to 2.3 mm.

Maintenance and Reliability Considerations

Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal, so avoid such conditions during storage and operation. The probe sealing material uses a Viton O-ring to maintain differential pressure between tip and case. While probes are not pressure tested before shipment, contact the custom design department if your application requires a pressure seal test. Regular inspection of the cable and connector for damage helps maintain signal integrity.

Selection Guide and Purchasing Advice

Before ordering, confirm your system requires the 330104-00-10-05-01-BR configuration: 0.5-meter cable with miniature coaxial ClickLoc connector and connector protector. The BR agency approval option indicates country-specific certification. For applications needing extended temperature range, note that the standard probe covers -52°C to +177°C.
