Bently Nevada 330101-00-11-10-02-00 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-11-10-02-00 is an 8 mm proximity probe belonging to the 3300 XL machinery protection family, designed specifically for non-contact shaft vibration and axial position measurements. Unlike other configurations in the 330101 series that feature unthreaded sections or armored jackets, this high-precision eddy-current probe is designed with a fully threaded 1.1-inch stainless steel case (0.0 in unthreaded length) and an unarmored standard 1.0-meter cable. Terminating in a standard miniature coaxial ClickLoc connector, this unit is engineered for compact, flush-mounted installations where physical clearance is minimal and hazardous area agency approvals are not required.

Features

• Fully Threaded Design: Features 0.0 in unthreaded length with a 1.1 in overall case length, allowing maximum thread engagement in compact bearing housings.
• Eddy-Current Sensing: Provides high-accuracy, non-contact displacement monitoring of critical rotating shafts.
• Robust Tip Material: The probe tip is molded from polyphenylene sulfide (PPS) for superior resistance to chemicals, moisture, and high temperatures.
• FEP Insulated Cable: Equipped with a 1.0-meter 75-ohm triaxial standard cable insulated with fluoroethylene propylene (FEP) for high signal reliability.
• Standard ClickLoc Connector: Gold-plated miniature coaxial ClickLoc connector (Option 02) offers a secure, vibration-resistant connection without needing a connector protector.
• Non-Hazardous Industrial Tuning: Formulated with Option 00 approvals, offering an economical choice for general-purpose, non-hazardous process areas.

Applications

The 330101-00-11-10-02-00 proximity probe is typically integrated into permanent monitoring loops for heavy machinery protection in the following applications:

• Radial vibration and axial position measurement of steam and gas turbine shafts
• Rotor displacement and wear monitoring on high-speed industrial compressors and gearboxes
• Fluid-film bearing performance monitoring in critical water, power generation, and petrochemical pumps
• Shaft runout and eccentricity measurements on large industrial motors and generators

Installation Guidelines

• Thread Installation: Thread the probe case into the 3/8-24 UNF bracket. The recommended installation torque is 7.5 N-m (66 in-lbf) with a maximum rated limit of 11.2 N-m (100 in-lbf).
• Probe Gap Calibration: Adjust the physical gap between the probe tip and the target surface to the system calibration standard (typically 1.27 mm or 50 mils) before securing locknuts.
• Cable Protection: Maintain a minimum cable bend radius of 25.4 mm (1.0 in) during routing. Ensure probe cables are routed away from high-power machinery cables to prevent inductive noise.
• Viton O-Ring Care: Avoid exposing the Viton pressure seal to temperatures below -34 degC (-30 degF) during operation to maintain sealing integrity against machinery oils.

Compliance and Certifications

• Electromagnetic Compatibility (EMC): European Directive 2014/30/EU, standards EN 61000-6-2 and EN 61000-6-4
