Bently Nevada 330707-00-20-10-12-00 3300 XL 11 mm Proximity Probe

Description

Option 00 (0.0 in unthreaded length) and Option 12 (miniature coaxial ClickLoc connector on FluidLoc cable) specify this 3300 XL 11 mm proximity probe configuration — 330707-00-20-10-12-00.

This unarmored eddy-current displacement probe has a 5/8-18 UNF thread body (base model 330707) with a 2.0-inch overall case length and a 1.0-meter total lead length. It integrates a FluidLoc cable that prevents process oils or liquids from leaking out of the machine housing through the cable internal structure. It is used for non-contact shaft vibration and axial position monitoring in rotating machinery environments, pairing with a 3300 XL 11 mm Proximitor sensor and extension cable without requiring hazardous area certifications (Option 00).

Features

• 5/8-18 UNF-2A thread body (base model 330707) without protective stainless steel armor.
• Option 00 unthreaded length specifies a fully threaded probe case.
• Option 20 overall case length provides a 2.0-inch threaded body for depth adjustment.
• Option 10 total length delivers a 1.0-meter (3.3 feet) integral coaxial cable.
• Option 12 FluidLoc cable prevents lubricating oil and other process liquids from leaking through the internal cable core.
• Gold-plated brass miniature male ClickLoc coaxial connector provides secure, vibration-resistant coupling without a separate connector protector.
• Option 00 agency approval indicates standard configuration where hazardous area certification is not required.
• Polyphenylene sulfide (PPS) probe tip material withstands harsh industrial chemical environments.

Applications

• Shaft radial vibration and axial position measurements on steam turbines, gas turbines, and centrifugal compressors.
• Shaft eccentricity and thrust displacement monitoring in high-pressure pumps and industrial fans.
• Machinery protection systems using 3300 XL 11 mm transducer configurations.
• Industrial locations requiring fluid-tight barrier penetration where oil migration through cabling must be stopped.

Installation Guidelines

Maintain proper mechanical clearance during installation. Ensure the probe tip is completely clear of adjacent metal structures to prevent crosstalk and side-loading errors. The minimum recommended target size is a flat surface with a diameter of 30.5 mm (1.2 in). Secure the probe case to a maximum torque of 45.2 N-m (400 in-lb), with 15.2 N-m (133 in-lb) recommended for 5/8-18 UNF cases. When routing the integral FluidLoc cable, maintain a minimum bend radius of 25.4 mm (1.0 in) and secure the cable to avoid mechanical abrasion or whipping. To prevent premature seal degradation, do not expose the probe to temperatures below -34 degC (-30 degF) if a differential pressure seal is required.

Compliance and Certifications

The 3300 XL transducer system complies with the following standards when used with compatible system components:

• EMC Directive 2014/30/EU (EN 61000-6-2, EN 61000-6-4)
• RoHS Directive 2011/65/EU
