Bently Nevada 330102-00-20-15-02-00 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330102-00-20-15-02-00 are listed below for quick reference:

Industry Applications and Operational ROI

In steam turbines, the 2 mm linear range captures shaft orbit and eccentricity data with high fidelity. For centrifugal compressors, the stainless steel case resists corrosion from process gases. By enabling early fault detection, the probe reduces maintenance costs and extends machinery life. Choosing the 330102-00-20-15-02-00 means investing in reliable data that supports predictive maintenance strategies.

Installation and Setup Guidance

Mount the probe with the 3/8-24 UNF thread into a suitable tap. The maximum thread engagement is 0.563 in. For radial vibration monitoring, set the initial gap to approximately -9 Vdc (1.27 mm). Use 3-conductor shielded triad cable for field wiring, 0.2 to 1.5 mm² (16 to 24 AWG). The maximum cable length between the Proximitor Sensor and the monitor is 305 meters (1,000 feet). Follow the frequency response graphs in the manual to account for signal rolloff at longer distances.

Maintenance and Reliability

The probe tip, made of polyphenylene sulfide (PPS), resists chemical attack and wear. The AISI 303 or 304 stainless steel case provides mechanical strength. While the probe is designed to seal differential pressure, it is not pressure tested before shipment. For applications below -34°C (-30°F), be aware that the pressure seal may fail prematurely. Periodic inspection of the cable and connector for damage is recommended. The probe exhibits less than a 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity per IEC 68-2-3.

Precision Vibration Monitoring with the Bently Nevada 3300 XL Probe

For engineers tasked with protecting critical rotating machinery, the Bently Nevada 330102-00-20-15-02-00 offers a proven solution. This 3300 XL 8 mm proximity probe delivers accurate displacement measurements, helping you detect shaft vibration and position changes before they lead to costly failures. Its robust design withstands demanding industrial conditions, making it a trusted choice for turbomachinery, compressors, and large pumps.

Compatibility and Integration

This probe works with the 3300 XL Proximitor Sensor system. When installed with intrinsically safe zener barriers (per drawing 141092) or galvanic isolators, it is approved for Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga. For non-incendive circuits (per drawing 140979), it is approved for Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc. Always verify the temperature classification (T1 through T5) against your ambient conditions.

Selection Guide and Purchasing Advice

When selecting a proximity probe, match the thread size, cable length, and connector to your installation. The 330102-00-20-15-02-00 is a standard 8 mm probe with a 1.5 m cable and miniature coaxial ClickLoc connector.
