Bently Nevada 330101-00-67-20-02-00 3300 XL 8 mm Proximity Probe

Description

The 330101-00-67-20-02-00 is a 3300 XL 8 mm proximity probe featuring a 3/8-24 UNF thread and a non-armored design. This specific configuration includes a 0.0 in unthreaded length (Option 00), a 6.7 in case length (Option 67), and a 2.0 m total system length (Option 20). It utilizes a miniature coaxial ClickLoc connector on a standard cable (Option 02) and is supplied without hazardous area agency approvals (Option 00).

As a core component of the 3300 XL 8 mm Proximity Transducer System, this probe is engineered for non-contact measurement of shaft vibration and axial position on critical rotating machinery. The system provides an accurate voltage output proportional to the distance between the probe tip and the observed conductive surface, making it essential for monitoring turbine, compressor, and pump train dynamics.

Features

• 3/8-24 UNF-2A threads for precise mounting in standard transducer housings.
• Non-armored, 8 mm diameter probe tip with rugged PPS material.
• 6.7 in overall case length for deep-reach installation requirements.
• 2.0 m total system length including integral lead.
• Miniature coaxial ClickLoc connector, standard cable type.
• Compatible with all 3300 XL Proximitor sensors and extension cables.
• Electrical and physical interchangeability with legacy 3300 5 mm and 8 mm components.

Applications

• Radial vibration measurement on fluid-film bearing machines.
• Axial position (thrust) monitoring.
• Rotor speed and phase reference (keyphasor) signaling.
• Reciprocating compressor rod drop and rod position monitoring.
• High-temperature or harsh industrial environments in power generation and petrochemical sectors.

Installation Guidelines

Ensure correct probe gap settings using the appropriate gap voltage methodology to maximize linear range. When mounting, do not exceed the recommended case torque of 11.2 Nm (100 in-lbf) for forward-mounted probes. Route cables away from high-voltage lines and ensure the minimum cable bend radius of 25.4 mm (1.0 in) is maintained to prevent signal degradation. All connectors should be kept clean and dry; hand-tighten the ClickLoc connectors until the internal locking mechanism clicks.

Compliance and Certifications

This unit (Option 00) is designated for standard applications where specific hazardous area certifications (CSA, ATEX, IECEx) are not required. Ensure installation adheres to local electrical codes for general-purpose industrial equipment.
