Bently Nevada 330103-00-21-10-02-00 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-21-10-02-00 are listed below for quick reference:

Industry Applications and Failure Prevention

By detecting shaft displacement early, operators can schedule maintenance before bearing wear or rubs escalate. The probe’s PPS tip and stainless steel case resist corrosion and wear, ensuring long-term stability in oil, steam, and chemical environments. The 1.0-meter cable with ClickLoc connector simplifies installation in tight spaces.

Installation and Setup Guidance

For reliable operation, use 3-conductor shielded triad cable with tinned field wiring (0.2 to 1.5 mm² / 16 to 24 AWG). The maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). When using longer wiring, refer to the frequency response graphs (Figures 10 and 12) for signal rolloff at high frequencies. Ensure the probe case thread engagement does not exceed 15 mm for M10x1 threads.

Maintenance and Reliability

The probe is designed to seal differential pressure between tip and case using a Viton® O-ring. While probes are not pressure tested prior to shipment, periodic inspection of the cable and connector for damage is recommended. Avoid exposing the probe to temperatures below –34°C (–30°F) to prevent premature failure of the pressure seal. The standard probe operates from –52°C to +177°C (–62°F to +350°F).

Reliable Vibration Sensing for Critical Machinery

In rotating machinery, undetected shaft vibration leads to costly downtime and catastrophic failures. The Bently Nevada 330103-00-21-10-02-00 3300 XL 8 mm Proximity Probe provides precise, non-contact displacement measurement to protect your assets. This probe is engineered for continuous operation in demanding industrial environments, offering a linear range of 2 mm (80 mils) that begins at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, corresponding to approximately 1.27 mm (50 mils).

Compatibility and Integration

This probe is part of the 3300 XL series and works with Bently Nevada Proximitor sensors and monitoring systems. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators. For non-incendive circuits, follow drawing 140979. The probe meets Class I, Zone 0 and Zone 2 hazardous area requirements as specified.

Selection Guide and Purchasing Advice

When selecting a replacement or spare probe, verify the total length, thread type, and connector configuration. The 330103-00-21-10-02-00 is a standard configuration with 1.0 m cable and ClickLoc connector. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
