Bently Nevada 330102-00-28-05-02-05 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330102-00-28-05-02-05 are listed below for quick reference:

Industry Applications

Turbine Shaft Vibration Monitoring

In steam and gas turbines, the probe's 2 mm linear range and -9 Vdc recommended gap setting enable precise radial vibration measurement. The PPS tip withstands high temperatures up to +177°C, ensuring stable performance in turbine bearing housings.

Compressor Clearance and Thrust Position

For centrifugal compressors, the probe's miniature coaxial ClickLoc connector simplifies installation in confined spaces. The stainless steel case resists corrosion from process gases, while the CSA/ATEX/IECEx approvals allow use in hazardous areas.

Pump Health Assessment

In critical pumps, the 0.5 meter cable length provides flexibility for proximity to the target. The probe's design maintains seal integrity under differential pressure, reducing false readings from moisture ingress.

Installation & Setup Guidance

Proper thread engagement is essential. The probe case thread is 3/8-24 UNF with a maximum thread engagement of 0.563 inches. Use a 3-conductor shielded triad cable with tinned field wiring (0.2 to 1.5 mm² or 16 to 24 AWG). The maximum field wiring length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). For optimal signal integrity, follow the frequency response graphs for longer cable runs. Set the gap to -9 Vdc for radial vibration applications.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage or contamination. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe's Viton O-ring seals against differential pressure; if seal integrity is critical, contact the custom design department for pressure testing. The probe weight is 323 g/m (11.4 oz).

Solving Vibration Monitoring Challenges in Harsh Environments

In rotating machinery, accurate shaft vibration measurement is critical for predictive maintenance and avoiding unplanned downtime. The Bently Nevada 330102-00-28-05-02-05 3300 XL 8 mm Proximity Probe is engineered to deliver reliable, non-contact displacement readings in demanding industrial settings. With its robust design and certified safety approvals, it provides a dependable solution for continuous monitoring in turbines, compressors, and pumps.

Compatibility & Integration
