Bently Nevada 330104-02-18-10-01-00 3300 XL 8 mm Proximity Probe with Armor

Description

330104-02-18-10-01-00 is an eddy-current proximity probe featuring an M10 x 1 threaded body with 20 mm unthreaded length and 180 mm overall case length. This specific configuration includes a 1.0 m total cable length protected by flexible stainless steel armor and is terminated with a miniature ClickLoc coaxial connector equipped with a connector protector. Unlike unarmored or longer probe variants, this short-lead, armored version provides robust mechanical shielding against physical abrasion and environmental hazards in tight physical spaces.

The probe works on the eddy-current principle to measure shaft vibration, axial position, and Keyphasor reference signals. It pairs with a 3300 XL extension cable and Proximitor sensor to complete a 5-meter or 9-meter transducer system. Standard AISI 303 stainless steel serves as the case material, and polyphenylene sulfide (PPS) comprises the probe tip. This unit contains Option 00, indicating no hazardous area agency approvals are required for the installation.

Features

• M10 x 1 metric thread configuration with 180 mm overall case length and 20 mm unthreaded length.
• Flexible stainless steel armor provides mechanical protection for the triaxial coaxial cable.
• 1.0 meter (3.3 feet) integrated cable length.
• Miniature coaxial ClickLoc connector with pre-installed connector protector prevents environmental ingress at the connection point.
• Option 00 approval rating designates a standard, non-certified configuration for non-hazardous environments.
• Interchangeable with non-XL 3300 series 5 mm and 8 mm components.

Applications

The armored protection on this probe makes it ideal for harsh industrial environments where the sensor lead is exposed to flying debris, routing wear, or accidental impact. Typical applications include fluid-film bearing housing installations, high-vibration steam and gas turbines, centrifugal compressors, and generators. The M10 x 1 metric threads allow direct replacement in international machinery configurations requiring metric mounting taps.

Installation Guidelines

Proper gapping is critical to prevent target contact and optimize linear measurement range. Ensure the probe is mounted rigidly in a bracket or threaded housing. Always observe the minimum cable bend radius of 25.4 mm (1.0 in) during routing to prevent internal conductor damage. Hand-tighten the gold ClickLoc connectors until they 'click' to establish a secure electrical connection. For the M10 x 1 threaded case, do not exceed the maximum rated installation torque of 22.6 N-m (200 in-lb).
