Bently Nevada 330103-02-17-05-02-05 3300 XL 8 mm Proximity Probe

Description

330103-02-17-05-02-05 specifies this 3300 XL 8 mm proximity probe configuration, featuring an M10 x 1 metric thread, 20 mm of unthreaded body length (Option 02), and an overall case length of 170 mm (Option 17). This unarmored probe is manufactured with a 0.5-meter total cable length (Option 05), a miniature coaxial ClickLoc connector on standard triaxial cable (Option 02), and carries CSA, ATEX, and IECEx agency approvals for hazardous areas (Option 05).

This proximity probe is used for non-contact shaft vibration and axial position measurements in critical industrial machinery. The M10 x 1 threaded body provides metric mounting compatibility, while the 170 mm overall case length provides the extended reach necessary for deep-recessed mounting locations. The system operates on the eddy-current principle, delivering output voltage directly proportional to the gap distance when paired with a matching 3300 XL Proximitor sensor and standard extension cable.

Features

• M10 x 1 metric threaded body constructed from AISI 303 or 304 stainless steel without armor.
• Option 02 unthreaded length of 20 mm prevents thread binding in standard recessed mounting brackets.
• Option 17 overall case length of 170 mm allows extended physical reach into machine casings.
• Option 05 total probe length of 0.5 meters (1.6 feet) connects directly to local junction boxes.
• Option 02 miniature coaxial ClickLoc gold-plated connector provides low-resistance signal coupling.
• Option 05 CSA, ATEX, and IECEx approvals allow deployment in certified hazardous locations.
• Polyphenylene sulfide (PPS) probe tip material withstands chemical exposure and high temperatures.
• TipLoc molding process creates a molecular bond between the probe tip and the stainless steel body.
• CableLoc design provides up to 330 N (75 lbf) of pull strength between the cable and the probe housing.

Applications

• Radial shaft vibration monitoring on high-speed fluid-film bearing machines such as steam turbines and centrifugal compressors.
• Axial thrust position and casing expansion tracking in rotating machinery protection systems.
• Keyphasor reference signals and speed measurement applications.
• Machinery diagnostics and predictive maintenance in chemical processing plants, refineries, and power generation facilities.

Installation Guidelines

• Limit thread engagement length to a maximum of 15 mm to prevent binding or mechanical interference during installation.
• Ensure that the minimum cable bend radius of 25.4 mm (1.0 in) is maintained at all times during routing to prevent cable shield damage.
• Tighten the probe case to the recommended torque of 7.5 N-m (66 in-lbf). Do not exceed the maximum limit of 22.6 N-m (200 in-lbf).
• Connectors must be finger-tight only. Do not exceed the maximum connector torque rating of 0.565 N-m (5 in-lbf).
• Maintain a physical distance or utilize isolation brackets if electrical isolation is required between the probe body and machine housing.

Compliance and Certifications

• CSA: Approved for hazardous areas when used with certified intrinsic barriers or non-incendive circuits.
• ATEX/IECEx: Certified for use in Zone 0, Zone 1, and Zone 2 explosive atmospheres with appropriate barrier devices.
• CE: Fully compliant with applicable European Union directives for electromagnetic compatibility.
