Bently Nevada 330104-02-24-10-01-00 3300 XL 8 mm Proximity Probe

Description

Option 02 (20 mm unthreaded length) and Option 01 (ClickLoc connector with protector) specify this 3300 XL 8 mm metric threaded probe with FEP-jacketed stainless steel armor — 330104-02-24-10-01-00.

This configuration features a 240 mm overall case length (Option 24) and a 1.0 meter total cable length (Option 10). It differs from standard unarmored models by providing an integrated protective stainless steel armor over the triaxial cable, preventing structural wear and mechanical abrasion in demanding rotating machinery environments. The inclusion of a connector protector on the coaxial ClickLoc interface seals the connection against oil, moisture, and debris, making it suitable for deep casing installations where environmental contaminants are common.

Features

• Stainless steel armor (AISI 302/304) provides mechanical protection with an FEP outer jacket.
• Miniature coaxial ClickLoc connector comes pre-fitted with a protective fluorosilicone sleeve.
• M10 x 1 metric threads with a 240 mm case length allow deep-reach insertion into machine casings.
• 20 mm unthreaded portion provides clearance through mounting bushings and brackets.
• 1.0 meter overall cable length matches standard proximity transducer system setups when paired with extension cables.
• Polyphenylene sulfide (PPS) tip material stands up to chemical exposures and high temperatures.

Applications

• Radial vibration and shaft position monitoring in fluid-film bearings.
• Axial thrust displacement tracking on steam turbines, gas turbines, and industrial compressors.
• Shaft speed and phase reference measurements (Keyphasor) on high-speed machinery.
• Deep-reaching bore and internal casing applications requiring armored mechanical protection.

Installation Guidelines

Ensure that the case threads of the probe are properly torque-tightened to a maximum value of 7.5 N-m (66 in-lbf) during casing installation. Maintain the minimum allowable cable bend radius of 25.4 mm throughout routing to prevent damage to the internal triaxial conductors. Ensure that the ClickLoc coaxial connection is hand-tightened and the connector protector is fully seated over the junction to block contaminants from entering the signal path.

Compliance and Certifications

RoHS compliant. Designed to interface directly with CE-compliant Bently Nevada 3300 XL Proximitor sensors and extension cables.
