Bently Nevada 330101-00-23-05-02-00 3300 XL 8 mm Proximity Probe

Description

Engineered for highly reliable machinery protection, the Bently Nevada 330101-00-23-05-02-00 is an 8 mm proximity probe that delivers precise, non-contact shaft vibration and displacement measurements in critical rotating machinery. Unlike other configuration variants in the 3300 XL 8 mm series, this specific configuration is defined by its fully threaded case housing with zero unthreaded length (0.0 inches) and a compact 2.3-inch case body. It features a 0.5-meter (1.6 feet) total probe cable length, which must be connected to a matching extension cable to complete a 5.0-meter or 9.0-meter monitoring system chain. The probe is unarmored and comes with a standard miniature ClickLoc coaxial connector, and is intended for non-hazardous locations where agency approvals are not required.

Features

• Fully threaded 3/8-24 UNF-2A case with 0.0 inches of unthreaded length and 2.3 inches of overall case length.
• Standard unarmored coaxial cable configuration for flexible routing within protective conduits.
• Integral 8 mm probe tip utilizing robust eddy-current sensing technology.
• 0.5-meter (1.6 feet) cable length designed to match 5-meter or 9-meter transducer system chains.
• Miniature gold-plated coaxial ClickLoc connector ensures low-noise signal transition to extension cables.
• Viton O-ring seal provides internal fluid sealing between the probe tip and casing.
• Exceptionally wide operating temperature limits from -52 degC to +177 degC (-62 degF to +350 degF).

Applications

• Shaft radial vibration and axial position measurement in steam and gas turbines.
• Rotor displacement monitoring in large industrial centrifugal compressors and pumps.
• Thrust position and oil film thickness monitoring in fluid-film bearings.
• High-speed rotating machine diagnostics and automated alarm shutdown systems.

Technical Specifications

Installation Guidelines

• Nominal Probe Gap: Align the probe tip at the designated calibration distance (usually 1.27 mm or 50 mils) from the shaft target material.
• Thread Engagement Limit: Ensure that the thread engagement inside the bracket or machine housing does not exceed 0.563 inches.
• Locknut Torque: Secure the probe case with the appropriate locknut. Ensure tightening torque does not deform the thread or damage internal sensor components.
• Cable Shielding: Ensure proper shielding and grounding practices are followed to prevent electromagnetic noise from degrading the vibration monitoring signal. Route coaxial probe cables in dedicated, isolated conduits or trays.

Compliance and Certifications

• EMC Directive: European Community Directive 2014/30/EU (EN 61000-6-2 and EN 61000-6-4)
• RoHS: European Directive 2011/65/EU and China RoHS compliance (EFUP of 15 years)
• Functional Safety: Rated for SIL 2 (Hardware Fault Tolerance HFT = 0) or SIL 3 (Hardware Fault Tolerance HFT = 1) in safety-instrumented vibration protection systems.
