Bently Nevada 330106-00-04-10-02-00 3300 XL 8 mm Reverse Mount Proximity Probe

Description

Bently Nevada 330106-00-04-10-02-00 specifies a 3300 XL 8 mm reverse mount proximity probe configured with a metric M10 x 1 thread, 0 mm unthreaded length (Option 00), and a 40 mm overall case length (Option 04). This non-contacting sensor utilizes eddy-current technology to measure physical parameters such as shaft radial vibration, axial thrust position, and reference speed on rotating machinery. The reverse-mount configuration is specifically designed for installation from the rear side of mounting brackets or deep casings where conventional front-mount access is restricted.

Unlike standard 330106-05-30-10-02-00 configurations that feature a fixed 5.0 mm unthreaded length and 30 mm case length, this specialized option (00-04) features a fully threaded 40 mm case with zero unthreaded casing, allowing direct depth customization and maximum thread contact. The probe features a 1.0-meter (3.3 feet) integrated coaxial cable (Option 10) terminated with a miniature ClickLoc coaxial connector (Option 02) for secure, click-lock pairing with standard extension cables. This configuration does not include hazardous area agency certification markings (Option 00) and is intended for general industrial utility.

Features

• Fully Threaded Body: Option 00 specifies a 0 mm unthreaded length, allowing maximum thread contact over the case body.
• Metric Housing: Option 04 configures a 40 mm overall case length with M10 x 1 metric casing threads.
• Optimum Cable Length: Option 10 includes a 1.0-meter (3.3 feet) integrated coaxial cable.
• Secure Interconnect: Option 02 designates a miniature male coaxial ClickLoc connector with standard cable (no protector).
• Standard Industrial Version: Option 00 provides a reliable, non-certified configuration suited for general non-hazardous environments.
• Reverse-Mount Design: Designed for installation through the rear of a sleeve or bracket, protecting the cable interface inside the machine casing.
• Eddy-Current Sensing: Standard 8.0 mm tip diameter provides a linear range of 2.0 mm (80 mils) on AISI 4140 steel.

Applications

The 330106 series reverse-mount probes are utilized across various industrial sectors such as power generation, oil and gas, petrochemicals, and heavy manufacturing. Key applications include:

• Shaft radial vibration measurement on high-speed industrial turbine bearings.
• Axial thrust displacement monitoring to protect centrifugal compressors and gearboxes.
• Keyphasor reference trigger and rotational speed tracking on electric motors and fans.
• Deep casing installations where external probe adjustment is necessary through a reverse sleeve setup.

Installation Guidelines

Proper installation ensures accurate system measurement. Observe the following engineering guidelines:

• Depth Positioning: Prior to threading, ensure the reverse-mount bracket is clean of debris. Do not exceed the maximum thread engagement limit of 15 mm.
• Gap Adjustment: Tighten the probe until it contacts the target face, then back it off to the required gap. A voltage reading of -9 Vdc at the Proximitor output indicates the nominal mid-range gap of 1.27 mm (50 mils).
• Cable Mating: Wipe connector surfaces clean of dust and oil before assembly. Push and turn the ClickLoc connectors until they click; do not use locking pliers on standard connectors.
• Bend Protection: Support and secure the coaxial lead using cable clamps or conduits. Maintain a bend radius greater than 25.4 mm (1.0 in) to prevent coaxial insulation degradation.

Compliance and Certifications

This model is built to standard industrial quality guidelines but is configured without pre-configured hazardous area regional approvals. Ideal for applications outside classified explosive zones:

• RoHS compliant for material hazardous substance restrictions.
• CE compliant for industrial electromagnetic compatibility when installed within an approved Bently Nevada monitor rack system.
• Built in accordance with ISO 9001 quality management system manufacturing procedures.
