Bently Nevada 330104-15-23-50-02-00 3300 XL 8 mm Proximity Probe, Metric

Why Choose the Bently Nevada 330104-15-23-50-02-00 for Your Vibration Monitoring Needs?

When machinery vibrations threaten production uptime, precise measurement becomes critical. The Bently Nevada 330104-15-23-50-02-00 3300 XL 8 mm Proximity Probe delivers reliable, accurate data for rotating equipment protection. This metric probe, part of the trusted 3300 XL series, offers a robust design with a polyphenylene sulfide (PPS) tip and a stainless steel case. It provides a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. With a recommended gap setting of -9 Vdc for radial vibration, this probe ensures consistent performance in demanding industrial environments.

Technical Specifications Breakdown

Understanding the key parameters helps you integrate this probe effectively. The 330104-15-23-50-02-00 features a 5.0-meter cable length, designed exclusively for use with the 5 meter Proximitor sensor. Its miniature coaxial ClickLoc connector simplifies installation and provides a secure connection. The probe case thread is M10 x 1, with a maximum thread engagement of 15 mm. Nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 8.73 ± 0.50 Ω at 5.0m. These specifications ensure compatibility and repeatable measurements in your monitoring system.

Industry Applications for Reliable Monitoring

This proximity probe excels in critical rotating machinery applications. Use it for radial vibration and position monitoring of turbines, compressors, pumps, and motors. The 3300 XL 8 mm design withstands harsh conditions, with a standard probe temperature range of -52°C to +177°C (-62°F to +350°F). For extended temperature needs, the probe tip handles -52°C to +218°C (-62°F to +425°F), while the cable and connector tolerate up to +260°C (-60°F to +500°F). This wide range suits both standard and high-temperature processes, reducing the risk of sensor failure.

Installation and Setup Guidance

Proper installation maximizes probe performance. Use 0.2 to 1.5 mm² (16 to 24 AWG) field wiring with a 3-conductor shielded triad cable. The maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Mount the probe with the M10 x 1 thread, ensuring the unthreaded length of 150 mm and overall case length of 230 mm fit your application. The 5-meter cable is pre-terminated with the ClickLoc connector, simplifying field connections. Always verify the gap setting for your specific target and monitor requirements.

Maintenance and Reliability

Routine inspection ensures long-term accuracy. The probe case material—AISI 303 or 304 stainless steel—resists corrosion in most industrial environments. The PPS tip offers excellent durability against wear. The probe is designed to seal differential pressure between tip and case using a Viton O-ring. Note that probes are not pressure tested before shipment; contact the custom design department if pressure seal testing is needed. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal, so plan your installation environment accordingly.

Compatibility and Integration

The 330104-15-23-50-02-00 integrates seamlessly with Bently Nevada monitoring systems. It is intended for use with the 5 meter Proximitor sensor only. The probe supports intrinsically safe installations when used with approved zener barriers or galvanic isolators per drawing 141092, achieving Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga. For non-incendive circuits per drawing 140979, it meets Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc. These certifications allow deployment in hazardous areas, expanding your monitoring capabilities.

Selection Guide and Purchasing Advice

Before ordering, confirm your system requirements. Verify the total length option—5.0 meters (16.4 feet)—matches your installation. The 330104-15-23-50-02-00 includes the miniature coaxial ClickLoc connector with standard cable. Ensure your Proximitor sensor is the 5-meter version for proper operation.
