Bently Nevada 330103-00-18-10-12-05 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-18-10-12-05 are listed below for quick reference:

Industry Applications: Solving Real-World Problems

Steam Turbine Shaft Vibration Monitoring

In power generation, steam turbines operate at high speeds and temperatures. The 3300 XL probe's PPS tip and stainless steel case withstand the harsh environment, while its linear range of 2 mm provides precise vibration data for early fault detection.

Compressor Protection in Oil & Gas

Centrifugal compressors in refineries face pressure differentials and corrosive atmospheres. The probe's Viton O-ring seal design (differential pressure between tip and case) ensures reliable operation. The CSA, ATEX, and IECEx approvals allow installation in hazardous areas when used with appropriate barriers.

Paper Mill Roll Alignment

Paper machines require precise roll alignment to prevent web breaks. The probe's miniature coaxial ClickLoc connector and FluidLoc cable simplify installation in tight spaces, while the 1.0 meter cable length suits typical machine train layouts.

Installation & Setup Guidance

Field Wiring Best Practices

Use 3-conductor shielded triad cable with tinned wiring (0.2 to 1.5 mm² / 16 to 24 AWG). Maximum cable length between the 3300 XL Proximitor Sensor and monitor is 305 meters (1,000 feet). For high-frequency signals, refer to the frequency response graphs to account for signal roll-off at longer lengths.

Gap Setting for Radial Vibration

Set the recommended gap to -9 Vdc, approximately 1.27 mm (50 mils) from the target. This ensures the probe operates within its linear range (0.25 to 2.3 mm). Use a precision shim and voltage measurement during installation.

Thread Engagement Limits

The probe case thread (M10 x 1) has a maximum engagement length of 15 mm. Do not exceed this to avoid mechanical interference or damage.

Maintenance & Reliability

Temperature Considerations

Standard probes operate from -52°C to +177°C. For extended temperature applications (tip up to +218°C, cable up to +260°C), use the extended range variant. Note that exposure below -34°C (-30°F) may cause premature pressure seal failure.

Humidity Resistance

The probe exhibits less than 3% change in Average Scale Factor (ASF) when tested at 93% humidity per IEC 68-2-3 for up to 56 days. This makes it suitable for high-humidity environments like paper mills or offshore platforms.

Pressure Seal Integrity

The probe is designed to seal differential pressure between tip and case using a Viton O-ring. Probes are not pressure tested before shipment. If your application requires a pressure seal test, contact the custom design department.

The Challenge of Reliable Vibration Monitoring in Harsh Environments

Rotating machinery in industrial plants operates under extreme conditions—high temperatures, humidity, and pressure differentials. A failure in vibration sensing can lead to catastrophic downtime.

Compatibility & Integration

The 330103-00-18-10-12-05 is part of the 3300 XL system and works with 3300 XL Proximitor Sensors. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators. For non-incendive circuits, use drawing 140979. Always verify compatibility with your monitoring system.

Selection Guide & Purchasing Advice

When selecting a proximity probe, consider the target material, temperature range, and cable length. For longer runs, choose a different total length option. Contact AutoDCSTech for lifecycle status and availability before ordering.
