Bently Nevada 330101-00-25-10-02-05 3300 XL 8 mm Proximity Probe

Description

330101-00-25-10-02-05 specifies this 3300 XL 8 mm proximity probe configuration with a 0.0 in unthreaded length (fully threaded case), a 2.5 in overall case length, a 1.0 meter (3.3 feet) total cable length, a miniature coaxial ClickLoc connector on standard cable without an integrated connector protector, and CSA/ATEX/IECEx hazardous area approvals.

Unlike other configurations in the 330101 family, Option 02 provides a standard ClickLoc coaxial connector without an integrated protector, making it suitable for standard conduit runs or enclosed spaces where additional bulk is undesirable. Furthermore, its 1.0-meter total length (Option 10) connects directly to a matching 3300 XL extension cable in 5-meter or 9-meter transducer systems. The 2.5-inch overall case length (Option 25) with a fully threaded body (Option 00) allows exact mechanical positioning within bearing casings or machinery enclosures. This non-contacting eddy-current probe is used for static shaft position and dynamic shaft vibration monitoring when paired with a compatible 3300 XL Proximitor sensor.

Features

• Option 00 specifies a fully threaded probe body with 0.0 inches of unthreaded length.
• Option 25 defines a 2.5-inch overall case length with standard 3/8-24 UNF threads.
• Option 10 provides a 1.0-meter (3.3 feet) standard FEP-insulated coaxial cable.
• Option 02 designates a miniature coaxial ClickLoc connector on standard cable without an integrated connector protector.
• Option 05 offers agency approvals including CSA, ATEX, and IECEx certifications for hazardous environments.
• 8 mm tip diameter proximity probe designed for non-contact eddy-current displacement measurement.
• Probe case constructed from AISI 303 stainless steel for environmental protection.
• Chemically resistant polyphenylene sulfide (PPS) probe tip material for long-term industrial service.

Applications

• Steam and gas turbine shaft vibration and axial position measurements.
• Compressor rotor displacement and shaft position monitoring.
• Bearing housing mechanical vibration monitoring in pumps and fans.
• Permanent rotating machinery protection in power generation, chemical, and refining facilities.

Installation Guidelines

Maintain the standard probe gap as specified by the system calibration (typically 1.27 mm or 50 mils). Route the coaxial cable with proper shielding and grounding to prevent signal interference. Avoid tight bends by maintaining a minimum bend radius of 25.4 mm (1.0 in). Tighten the probe case to the recommended installation torque of 11.2 N-m (100 in-lbf), avoiding the maximum structural limit of 33.9 N-m (300 in-lbf). Coaxial connections must be finger-tightened before applying a final connector torque of 0.565 N-m (5 in-lbf) using a dedicated connector wrench.

Compliance and Certifications

Associated with Option 05: CSA, ATEX, and IECEx approvals for use in hazardous area classifications.
