Bently Nevada 330104-06-14-50-02-00 3300 XL 8 mm Proximity Probe

Reliable Vibration Monitoring for Critical Machinery

When unplanned downtime threatens production targets, the Bently Nevada 330104-06-14-50-02-00 3300 XL 8 mm Proximity Probe delivers the precise measurements needed for early fault detection. This metric probe is designed for continuous monitoring of shaft vibration and position in rotating equipment such as turbines, compressors, and pumps. Its robust construction and proven 3300 XL platform help reduce maintenance costs and extend machinery life.

Solving Installation and Environmental Challenges

Installing proximity probes in tight or high-temperature areas often leads to cable damage and signal degradation. The 330104-06-14-50-02-00 addresses this with an armored design and a miniature coaxial ClickLoc connector that ensures secure, reliable connections even in high-vibration environments. The 5.0-meter cable is specifically matched to the 5 meter Proximitor sensor for optimal performance. For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with a maximum length of 305 meters (1,000 feet) between the Proximitor and monitor.

Applications Across Heavy Industries

This probe excels in applications where precise shaft proximity measurement is critical:

Steam and gas turbines: Monitors radial vibration and thrust position to prevent blade rubs and bearing failures.

Centrifugal compressors: Detects shaft instability and misalignment early, avoiding catastrophic damage.

Large pumps and fans: Provides continuous data for condition-based maintenance programs, reducing unplanned outages.

Installation and Setup Guidance

For accurate readings, mount the probe with the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) from the target surface. The linear range begins at about 0.25 mm (10 mils) and extends to 2.3 mm (90 mils). Ensure the probe case thread engagement does not exceed 15 mm. When using intrinsically safe barriers per drawing 141092 or galvanic isolators, the probe achieves Class I, Zone 0 ratings (AEx/Ex ia IIC T5...T1 Ga). For non-incendive installations per drawing 140979, it meets Class I, Zone 2 requirements.

Maintenance and Reliability Tips

Regularly inspect the probe cable and connector for wear, especially in high-temperature areas. The standard probe operates from -52°C to +177°C; exposing it below -34°C (-30°F) may cause premature pressure seal failure. The probe seals differential pressure between tip and case using a Viton® O-ring, but it is not pressure tested before shipment. Contact the custom design department if pressure testing is required for your application. The probe tip material (PPS) resists many chemicals, and the stainless steel case provides corrosion resistance in humid environments (less than 3% change in Average Scale Factor after 56 days at 93% humidity per IEC 68-2-3).

Compatibility and Integration

This 5.0-meter probe is designed exclusively for use with the 5 meter Proximitor sensor. It integrates seamlessly with Bently Nevada monitoring systems for real-time vibration analysis and protection. The miniature coaxial ClickLoc connector simplifies installation and ensures a secure connection even in tight spaces.

Selection and Purchasing Advice

Before ordering, verify that your system requires a 5.0-meter probe length and M10 x 1 thread. Confirm the unthreaded length (60 mm) and overall case length (140 mm) match your mounting requirements. For agency approvals, this unit ships with the "Not required" option (code 00). If you need pressure testing or extended temperature range probes (up to +218°C for the tip), contact plcmatrix.com for custom options.
