Bently Nevada 330101-00-20-10-10-02-05 3300 XL 8 mm Proximity Probe

Description

330101-00-20-10-10-02-05 is a 3300 XL 8 mm proximity probe featuring a fully threaded 3/8-24 UNF thread body with 0.0 inches of unthreaded length, a 2.0-inch overall case length, a 1.0-meter total cable length, and a standard miniature coaxial ClickLoc connector with CSA, ATEX, and IECEx hazardous area approvals.

This unarmored variant (330101) provides a direct physical contrast to armored alternatives like the 330102 series, which incorporate a stainless steel braid for mechanical wear resistance. The -02 connector option provides a bare miniature coaxial ClickLoc connector, distinguishing it from -01 configurations that include a factory-installed connector protector. Operating on the eddy-current principle, this probe pairs with a 3300 XL Proximitor sensor and an extension cable to form a complete transducer system for non-contact vibration and shaft position measurements in critical rotating machinery.

Features

• Unarmored probe configuration designed for standard conduit or protected housing installations.
• Fully threaded case (0.0 inches unthreaded length) and 2.0-inch overall case length with 3/8-24 UNF threads.
• 1.0-meter integrated standard cable length for standard-reach transducer chains.
• Miniature coaxial ClickLoc connector (Option 02) without connector protector.
• Approved for hazardous areas with CSA, ATEX, and IECEx certification (Option 05).

Applications

This proximity probe is used in machinery protection systems to monitor mechanical parameters on rotating equipment. Typical industrial applications include:

• Steam and gas turbine shaft vibration and axial position monitoring.
• Compressor and high-speed pump rotor displacement measurements.
• Permanent installations in hydrodynamic bearing housings or machine casings.

Installation Guidelines

Proper physical installation and electrical connections are required for reliable measurement performance:

• Mount the probe with the appropriate probe gap set in accordance with system calibration specifications.
• Ensure the probe cable is routed away from high-voltage wiring to minimize electrical noise interference.
• Route the cable with appropriate physical shielding and grounding practices standard for vibration monitoring systems.
• Avoid twisting or over-torquing the coaxial cable during installation to prevent damage to the inner conductor.

Compliance and Certifications

This transducer component complies with international standards for hazardous area installations when used with compatible certified barriers and Proximitor sensors:

• CSA: Certified for use in designated hazardous locations.
• ATEX: Certified for explosive atmospheres.
• IECEx: Global hazardous area certification scheme.
