Bently Nevada 330104-01-06-10-01-00 3300 XL 8 mm Proximity Probe, Metric

Solving Vibration Monitoring Challenges in Rotating Machinery

When unexpected machine downtime threatens production schedules, precise vibration measurement becomes critical. The Bently Nevada 330104-01-06-10-01-00 3300 XL 8 mm Proximity Probe delivers the accuracy and durability needed for continuous monitoring of shaft vibration and position in turbines, compressors, and pumps. This metric probe, part of the trusted 3300 XL series, provides a linear range of 2 mm (80 mils) starting at approximately 0.25 mm (10 mils) from the target, ensuring reliable data for predictive maintenance programs.

Technical Specifications Breakdown

The 330104-01-06-10-01-00 features a probe tip made of polyphenylene sulfide (PPS) and a case constructed from AISI 303 or 304 stainless steel (SST). Its M10x1 thread allows secure mounting, with a maximum thread engagement of 15 mm. The probe operates within a standard temperature range of -52°C to +177°C (-62°F to +350°F) and withstands humidity up to 93% with less than 3% change in Average Scale Factor (ASF). Nominal DC resistance from center conductor to outer conductor is 7.59 ± 0.50 ohms for the 1.0 meter length. Recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils).

Industry Applications

This proximity probe is ideal for critical rotating equipment in power generation, oil and gas, and petrochemical facilities. For example, in a steam turbine train, the 330104-01-06-10-01-00 monitors shaft radial vibration and axial position, providing early warning of bearing wear or misalignment. Its rugged stainless steel case and PPS tip resist harsh process environments, while the optional armor protects against mechanical damage during installation and operation.

Installation & Setup Guidance

Proper installation ensures optimal performance. Use the recommended probe case torque of 11.2 N•m (100 in•lbf) for standard forward mounted probes, with a maximum of 33.9 N•m (300 in•lbf). 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 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). For best results, set the gap to -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration measurements.

Maintenance & Reliability

Regular inspection of the probe cable and connector helps maintain signal integrity. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. The Viton O-ring seal is designed to handle differential pressure between the probe tip and case, but probes are not pressure tested prior to shipment. Contact the custom design department if pressure seal testing is required for your application.
