Bently Nevada 330703-000-060-10-11-00 3300 XL 11 mm Proximity Probe

Description

Designed specifically for industrial turbomachinery protection, the Bently Nevada 330703-000-060-10-11-00 provides high-accuracy non-contact shaft displacement and vibration measurement. This 3300 XL 11 mm Proximity Probe is engineered to withstand harsh, high-pressure environments, using specialized materials and construction to deliver long-term calibration stability in critical machine monitoring systems.

Features

• FluidLoc Cable Technology: Prevents oil, water, and other process fluids from leaking through the interior of the coaxial cable.
• ClickLoc Coaxial Connector: Features an integrated connector protector that guards the coaxial connection from moisture, dirt, and mechanical stress.
• Polyphenylene Sulfide (PPS) Tip: Molded tip provides high resistance to chemical attack and thermal degradation.
• Corrosion-Resistant Case: Manufactured from AISI 304 stainless steel to ensure mechanical strength in aggressive atmospheres.

Applications

• Steam and gas turbine radial vibration and axial thrust position tracking.
• Hydroelectric generator shaft alignment and thermal expansion monitoring.
• High-speed industrial compressor and boiler feed pump bearing diagnostics.

Alternative Models & Compatibility

The 11 mm proximity probe system has a larger linear range (4.0 mm) compared to standard 8 mm probes (2.0 mm). Always match this probe with a dedicated 3300 XL 11 mm Proximitor Sensor. Intermixing an 11 mm probe with an 8 mm Proximitor sensor will cause extreme scale factor errors and render the displacement readings inaccurate.

Application Pitfalls & Engineering Notes

The FluidLoc cable specification (Option 11) is critical for installations where the machine case operates under oil mist or slight pressure differential. Non-FluidLoc cables can allow oil to bypass internal barriers via capillary action inside the cable jacket, resulting in contamination of the external junction box over long operational intervals.

Commissioning & Wiring Tips

During initial commissioning, avoid over-torquing the ClickLoc coaxial connection. Hand-tighten until a positive click is felt, then slide the connector protector sleeve firmly over the joint. To prevent interference issues, ensure that the extension cable shield is single-point grounded at the monitor rack, and not grounded inside the local junction box.
