Bently Nevada 330103-00-08-15-02-05 3300 XL 8 mm Proximity Probe

Description

Option 00 (0 mm unthreaded length) and Option 08 (80 mm case length) specify this 3300 XL 8 mm proximity probe configuration — 330103-00-08-15-02-05. This metric-threaded proximity probe features an unarmored standard coaxial cable (Option 15, 1.5 m total length) terminated with a miniature coaxial ClickLoc connector (Option 02, no protector) and carries hazardous area certifications (Option 05) including CSA, ATEX, and IECEx approvals.

As an unarmored configuration with M10 x 1 metric threading, this probe is suited for machinery installations where direct conduit routing or auxiliary sleeving is used, differing from the armored 330104 series or standard 3/8-24 UNF threaded 330101 models. It serves as an eddy-current transducer to measure static (position) and dynamic (vibration) shaft displacement against a ferromagnetic target, such as an AISI 4140 steel shaft, in critical rotating machinery monitoring applications.

Features

• Option 00 specifies a fully threaded probe body with 0 mm unthreaded length.
• Option 08 provides an 80 mm metric-threaded (M10 x 1) steel case.
• Option 15 delivers a 1.5-meter (4.9 ft) total cable length for compact proximity systems.
• Option 02 provides a miniature ClickLoc coaxial connector without a connector protector on a standard cable.
• Option 05 approvals package includes international CSA, ATEX, and IECEx hazardous area certifications.
• Molded PPS plastic probe tip achieves high chemical resistance and robust mechanical strength.
• Linear range of 2.0 mm (80 mils) when paired with a matching 3300 XL Proximitor Sensor and extension cable.

Applications

• Shaft vibration (radial dynamic displacement) monitoring on high-speed turbines and compressors.
• Axial thrust position measurement on steam/gas turbines, generators, and pumps.
• Keyphasor and phase reference tracking for rotating machinery diagnostics.
• Eccentricity and shaft alignment measurements on industrial gearboxes.

Installation Guidelines

• Ensure the probe-to-extension-cable connection is kept clean and dry during assembly.
• Maintain a minimum bend radius of 25.4 mm (1.0 in) during cable routing to prevent signal attenuation.
• Use a thread-engagement depth of no more than 15 mm to avoid binding or damaging threads during installation.
• Recommended gap configuration is 1.27 mm (50 mils) to place the probe in the center of its linear range.
• Protect coaxial connections with silicone tape or junction boxes in environments exposed to moisture or oil.
