Bently Nevada 330101-00-77-20-02-05 3300 XL 8 mm Proximity Probe

Description

330101-00-77-20-02-05 specifies this 3300 XL 8 mm proximity probe configuration featuring a fully threaded 3/8-24 UNF steel body, a 7.7-inch overall case length, a 2.0-meter total cable length, and standard coaxial ClickLoc connector with CSA/ATEX/IECEx hazardous area agency approvals. This unarmored, non-contact eddy-current displacement sensor is used in 3300 XL monitoring systems for shaft vibration and axial position measurement.

This specific configuration differs from other variants in the 330101 series through its exact combination of a 7.7-inch fully threaded case (Option B: 77) and 2.0-meter cable length (Option C: 20) with no unthreaded section (Option A: 00). It pairs with a 3300 XL Proximitor sensor and an extension cable to form a complete 3300 XL 8 mm transducer system, interfacing directly with 3500 rack I/O modules.

Features

• Option 00 unthreaded length specifies a fully threaded 3/8-24 UNF probe body for maximum thread engagement.
• Option 77 overall case length provides a 7.7-inch physical casing for installations requiring deeper reach.
• Option 20 total length supplies a 2.0-meter standard coaxial cable without armor.
• Option 02 connector incorporates a miniature coaxial ClickLoc connector.
• Option 05 agency approval grants CSA, ATEX, and IECEx certifications for hazardous environments.
• 8 mm tip diameter performs eddy-current non-contact displacement measurement.
• Stainless steel probe body and tip construction tolerate industrial machine environments.

Applications

• Steam and gas turbine shaft vibration monitoring
• Compressor and pump rotor axial displacement measurement
• Critical rotating machinery protection and condition monitoring
• Industrial machine permanent installations on bearing housings

Installation Guidelines

During installation, mount the probe with the appropriate probe gap as specified by system calibration. Route the coaxial cable using proper shielding and grounding practices standard for machinery vibration monitoring systems. Avoid exceeding the maximum thread engagement lengths (0.563 inches for 3/8-24 UNF threads) to prevent binding or damage to the probe casing during installation.

Compliance and Certifications

The 330101-00-77-20-02-05 configuration includes the Option 05 agency approval package. This certifies the probe for use in hazardous areas under the following approvals:

• CSA
• ATEX
• IECEx
