Bently Nevada 330701-00-15-50-01-CN 3300 XL 11 mm Proximity Probe

Description

Engineered for high-reliability vibration and shaft position monitoring in demanding industrial environments, the Bently Nevada 330701-00-15-50-01-CN belongs to the rugged 3300 XL 11 mm Proximity Probes family. This system provides a wider linear measurement range compared to standard 8 mm probes, making it highly effective for applications requiring larger displacement tracking. The specific configuration features an unthreaded length of 0.0 inches, an overall case length of 1.5 inches, and a total cable length of 5.0 meters (16.4 feet). It comes equipped with a miniature coaxial ClickLoc connector with an integrated connector protector, ensuring exceptional signal integrity and resistance to fluid ingress under harsh operational conditions.

Features

• Extended Linear Range: Part of the 3300 XL 11 mm series, delivering accurate displacement measurements over larger mechanical spans.
• Robust Case Material: Constructed from AISI 304 stainless steel (SST) for long-term corrosion resistance in harsh industrial environments.
• Durable Tip Design: The probe tip is molded from Polyphenylene sulfide (PPS) to resist high temperatures and chemical exposure.
• Environmental Protection: Sealing is achieved using a reliable Viton O-ring, designed to manage differential pressure between the probe tip and the case.
• High-Integrity Connection: Supplied with a miniature coaxial ClickLoc connector and a protective sleeve to guard against electrical noise and fluid contamination.

Applications

• Steam and gas turbine shaft vibration and axial position measurement.
• Hydroelectric generator shaft alignment and radial vibration monitoring.
• Large industrial compressors, expanders, and pump monitoring.
• Thrust and radial displacement tracking in heavy rotating machinery.

Empirical Engineering Insights

Alternative Models & Compatibility

The 11 mm proximity probe requires a matching 3300 XL 11 mm Proximitor Sensor for correct operation. Do not attempt to pair this probe with a standard 8 mm or 5 mm Proximitor Sensor, as the differences in coil impedance and calibration curves will cause severe non-linearity and rendering the machinery protection system inaccurate.

Application Pitfalls & Engineering Notes

Because 11 mm probes have a larger physical diameter, they are more susceptible to side-viewing (cross-talk) if mounted too close to adjacent metal structures or other probes. Ensure that you maintain the minimum clearance specifications outlined in the OEM technical reference to prevent unwanted signal interference and false vibration readings.

Commissioning & Wiring Tips

When routing the 5-meter coaxial cable, avoid tight bends that violate the minimum bend radius. Ensure that the ClickLoc coaxial connection is completely clean, dry, and free of oil or grease before sliding the connector protector into place. Even minor contamination on the gold pins can cause signal noise or mimic false shaft displacement.
