Bently Nevada 330102-00-50-10-01-05 3300 XL 8mm Proximity Probe

Description

Option 00 (0.0 in unthreaded length) and Option 50 (5.0 in overall case length) specify this armored 3300 XL 8 mm probe configuration — 330102-00-50-10-01-05. This eddy-current proximity probe features integral FEP-coated stainless steel armor protecting its coaxial cable from mechanical abrasion and severe physical wear in industrial plants. Unlike unarmored sibling variants such as the 330101, this armored configuration provides enhanced structural shielding for the cable run without introducing signal interference.

The probe operates within a 3300 XL 8mm transducer system, pairing with a 3300 XL extension cable and a matched Proximitor sensor. It provides non-contact displacement measurements to track shaft vibration, axial position, and rotating speed. This specific model is configured with a 1.0-meter total cable length (Option 10) terminated in a miniature coaxial ClickLoc connector shielded by an integrated fluorosilicone connector protector (Option 01). Under agency approval Option 05, the assembly is certified for use in intrinsically safe and hazardous environments.

Features

• Option 00 unthreaded case length providing full thread engagement along the entire body length.
• Option 50 case length specifying a 5.0-inch overall threaded probe housing.
• Option 10 total length specifying a 1.0-meter (3.3 feet) integrated cable.
• Option 01 connector type providing a miniature coaxial ClickLoc connector complete with an elastomeric connector protector.
• Option 05 approval option verifying compliance with ATEX, IECEx, and CSA hazardous area certifications.
• Flexible stainless steel armor surrounding the coaxial cable to guard against cutting, crushing, and sharp bends.
• Viton O-ring pressure seal rated to withstand differential pressure between the probe tip and case.

Applications

This armored proximity probe is used for non-contacting vibration and position measurements on industrial rotating machinery. Typical applications include:

• Radial shaft vibration monitoring on steam and gas turbines.
• Thrust position measurements on high-speed centrifugal compressors.
• Shaft eccentricity and differential expansion tracking on utility generators.
• Rotor speed and phase reference (keyphasor) sensing on pumps and industrial fans.
• Vibration monitoring in heavy mechanical environments where cable abrasion is a constant risk.

Installation Guidelines

• Maintain standard mounting thread engagement limits to prevent binding during installation (maximum 0.563 inches for 3/8-24 UNF threads).
• Establish the correct probe gap using a static calibrator or digital voltmeter linked to the Proximitor sensor output prior to final tightening.
• Connect the miniature coaxial ClickLoc connector finger-tight to the extension cable coaxial connector.
• Slide the fluorosilicone connector protector over the connection to insulate and seal the coaxial junction from moisture, oil, and external contaminants.
• Avoid twisting the armored casing during installation to prevent damage to the internal coaxial core.

Compliance and Certifications

• CSA certified for Class I, Division 1 and Zone 0 hazardous environments.
• ATEX certified for Ex ia IIC T5...T1 Ga explosive atmospheres.
• IECEx certified for intrinsically safe applications in explosive gas and dust environments.
