Bently Nevada 330103-02-07-10-02-00 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-02-07-10-02-00 are listed below for quick reference:

Industry Applications

This probe is commonly installed on steam turbines, centrifugal compressors, and large pumps where shaft radial vibration and axial position must be monitored continuously. The 2 mm linear range and -9 Vdc recommended gap setting allow precise measurement of dynamic motion. The PPS tip and stainless steel case withstand oil mist, moisture, and moderate chemical exposure typical in refineries and power plants.

Installation & Setup Guidance

Mount the probe using the M10 x 1 thread with a maximum thread engagement of 15 mm. Use 3-conductor shielded triad cable with tinned field wiring; the maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). For radial vibration applications, set the initial gap to -9 Vdc. Ensure the probe tip is clean and the target surface is smooth and electrically continuous.

Maintenance & Reliability

The probe is designed for long-term reliability with no moving parts. Inspect the cable and connector periodically for damage. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe seals differential pressure between tip and case using a Viton O-ring; contact the custom design department if pressure testing is required.

Precision Vibration Monitoring for Critical Machinery

In rotating machinery, undetected shaft vibration can lead to catastrophic failure and unplanned downtime. The Bently Nevada 330103-02-07-10-02-00 3300 XL 8 mm Proximity Probe provides accurate, non-contact displacement measurements essential for protecting turbines, compressors, and pumps. This probe is engineered for reliable performance in harsh industrial environments.

Compatibility & Integration

This probe works with Bently Nevada 3300 XL Proximitor Sensors and compatible monitoring systems. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it meets Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga; Class 1, Groups A, B, C, and D; Class II, Groups E, F, and G; Class III. For non-incendive circuits per drawing 140979, it meets Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc; Class 1, Division 2, Groups A, B, C, D; Class 1, Zone 2: AEx/Ex ec llC T5…T1 Gc.

Selection Guide & Purchasing Advice

When selecting a proximity probe, verify the required cable length, connector type, and agency approvals. The 330103-02-07-10-02-00 offers a 1.0 m cable with a miniature coaxial ClickLoc connector and no agency approval option.
