Bently Nevada 330103-00-02-20-02-05 3300 XL Probe Proksimit 8 mm

Description

Option 00 (0 mm unthreaded length) and Option 02 (20 mm overall case length) specify this metric M10 x 1 threaded probe configuration — 330103-00-02-20-02-05. This 3300 XL 8 mm proximity probe features a 2.0-meter standard cable (Option C: 20) with a miniature coaxial ClickLoc connector (Option D: 02) and is approved for hazardous environments under CSA, ATEX, and IECEx certifications (Option E: 05). Designed without mechanical armor, the probe operates as part of an eddy-current transducer system to measure shaft vibration, position, and speed on rotating machinery. It interfaces directly with a matching 3300 XL Proximitor sensor and standard extension cable.

Unlike variants configured with armored cabling (such as the 330104 series) or those featuring connector protectors (Option D: 01), this configuration utilizes an unarmored, lightweight coaxial line and a standard ClickLoc connector. The M10 x 1 metric thread is fully threaded along its entire 20 mm case length because there is no unthreaded section (Option A: 00), allowing for direct, low-profile mounting in machinery casings where space is limited.

Features

• Fully Threaded Case: Features an M10 x 1 metric thread with 20 mm of case length and 0 mm of unthreaded length, enabling direct mounting in shallow machine casings.
• Unarmored 2.0-Meter Cable: Equipped with a 2.0 m unarmored coaxial cable that provides reduced weight and flexibility during installation.
• ClickLoc Coaxial Connector: Utilizes a gold-plated ClickLoc connector to ensure low-resistance electrical connections without the bulk of integrated connector protectors.
• Agency Approved: Certified for hazardous areas (Option 05) with CSA, ATEX, and IECEx intrinsic safety and non-incendive approvals.
• PPS Probe Tip: Molded polyphenylene sulfide (PPS) tip ensures robust resistance against high temperatures and corrosive environments.

Applications

This probe configuration is used on rotating machinery across power generation, petrochemical, and water treatment industries. Specific applications include:

• Shaft radial vibration measurement on steam turbines and compressors.
• Axial shaft position tracking on industrial gas turbines and generators.
• Keyphasor speed and phase reference monitoring on machinery train shafts.

Installation Guidelines

• Probe Gap: Gap the probe target at the appropriate voltage using a digital multimeter connected to the Proximitor sensor output (typically -10.0 Vdc for the middle of the linear range).
• Mounting Torque: When mounting the M10 x 1 thread probe case, do not exceed the maximum rated torque of 22.6 N-m (200 in-lbf). Recommended installation torque is 7.5 N-m (66 in-lbf).
• Bend Radius: Ensure the unarmored FEP-insulated probe cable maintains a minimum bend radius of 25.4 mm (1.0 in) to prevent internal coaxial shielding damage.
• Connector Handling: Connectors must be kept clean and dry. Finger-tighten the ClickLoc coaxial connectors until they click to secure the connection.
