Bently Nevada 330104-02-24-10-01-00 3300 XL 8 mm Proximity Probe, Metric

What Is the Bently Nevada 330104-02-24-10-01-00?

When bearing vibration threatens to halt your rotating machinery, the Bently Nevada 330104-02-24-10-01-00 provides the precise measurement you need. This 3300 XL 8 mm proximity probe, part of the trusted 3300 XL series, delivers reliable displacement data for critical assets like turbines, compressors, and pumps. Designed with an M10 x 1 thread and armor, it withstands harsh industrial environments while maintaining accuracy.

Technical Specifications Breakdown

The 330104-02-24-10-01-00 offers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target and extending to 2.3 mm (90 mils). This corresponds to an output of approximately –1 to –17 Vdc. The recommended gap setting for radial vibration is –9 Vdc, roughly 1.27 mm (50 mils). The probe tip material is polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel. It operates in temperatures from –52°C to +177°C (–62°F to +350°F) for standard probes. The probe weighs 323 g/m (11.4 oz).

Industry Applications

In steam turbine monitoring, the 330104-02-24-10-01-00 detects shaft vibration and position changes that signal imbalance or misalignment. For centrifugal compressors, it provides real-time data to prevent catastrophic failure. Its robust construction suits both oil and gas and power generation environments. The probe's linear range and temperature tolerance make it ideal for continuous duty in high-heat zones.

Installation & Setup Guidance

Mount the probe using the M10x1 thread, ensuring maximum thread engagement of 15 mm. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable and tinned wiring. The maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Set the gap to –9 Vdc for radial vibration applications. Refer to frequency response graphs for signal rolloff at high frequencies with longer wiring.

Maintenance & Reliability

Inspect the probe tip and cable periodically for wear or 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. For extended temperature ranges, the probe tip can withstand up to +218°C (+425°F) and the cable up to +260°C (+500°F). Less than 3% change in Average Scale Factor occurs in 93% humidity per IEC 68-2-3 for up to 56 days.

Selection Guide & Purchasing Advice

Before ordering, verify that the unthreaded length (20 mm), overall case length (240 mm), and total length (1.0 meter) match your installation requirements. The miniature coaxial ClickLoc connector with connector protector and standard cable is included. Agency approval is not required for this variant.
