Bently Nevada 330105-02-12-05-12-05 3300 XL 8 mm Reverse Mount Proximity Probe

Description

330105-02-12-05-12-05 specifies a 3300 XL 8 mm reverse mount proximity probe featuring a 0.2 in unthreaded length (Option 02), 1.2 in overall case length (Option 12), a 0.5 meter total length (Option 05), a specialized FluidLoc cable with ClickLoc coaxial connector (Option 12), and CSA/ATEX/IECEx hazardous area agency approvals (Option 05).

This specific configuration incorporates a FluidLoc cable (Option 12), which is designed to prevent liquid or oil leakage along the interior of the cable jacketing into surrounding areas. This is particularly critical in applications where standard cable configurations (such as Option 02) cannot prevent oil or fluid bypass. With its reverse mount form factor and 3/8-24 UNF-2A threads, this probe is installed from the rear of the machine housing, making it highly suitable for confined spaces and heavy industrial turbine or compressor casing assemblies.

Features

• FluidLoc coaxial cable (Option 12) prevents internal fluid bypass along the cable sheath.
• Reverse mount configuration allows easy rear-entry installation in tight machine casings.
• Integrated gold-plated ClickLoc miniature coaxial connector for secure, reliable connection.
• 0.5-meter total length matches specific 3300 XL system calibration standards.
• Agency approval (Option 05) provides CSA, ATEX, and IECEx compliance for hazardous area zones.

Applications

• Fluid-film bearing machines (turbines, compressors, pumps, and generators).
• Shaft vibration and axial position measurements in environments with high oil or moisture presence.
• Keyphasor reference and speed measurement systems in confined casing geometries.
• Industrial rotating machinery protection systems.

Installation Guidelines

When installing the reverse mount probe, thread engagement should be monitored carefully to prevent binding. Ensure the coaxial connectors are tightened finger-tight only (for gold ClickLoc type). Route the FluidLoc cable securely through the designated probe sleeve or conduit to prevent mechanical wear. Proper isolation and grounding of the shield are recommended to maintain signal integrity.

Compliance and Certifications

Agency Approvals: CSA, ATEX, and IECEx (Intrinsically Safe and Non-Incendive classifications for Class I, Division 1/2 and Zone 0/1/2 environments). Standard international package (does not include -CN NEPSI/CCC China hazardous area package).
