Bently Nevada 330101-00-41-15-12-05 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-41-15-12-05 is a specialized, non-contact eddy-current proximity probe from the 3300 XL 8 mm Proximity Transducer System family. This variant is specifically engineered with a patented FluidLoc cable (Option 12), which prevents process oil or other lubricating liquids from migrating and leaking out of the machine casing through the interior of the cable. It is a critical instrumentation component for heavy-duty industrial rotating machinery applications where sealing integrity is vital.

This probe configuration incorporates a standard 3/8-24 UNF threaded body without protective armor, featuring an overall case length of 4.1 inches and no unthreaded length (fully threaded). With a total cable length of 1.5 meters (4.9 feet) and a miniature ClickLoc coaxial connector, the probe pairs seamlessly with a 3.5-meter or 7.5-meter extension cable to complete a 5-meter or 9-meter monitoring chain. This unit is certified for hazardous environments under the Option 05 agency approval, carrying CSA, ATEX, and IECEx certifications.

Features

• FluidLoc Cable Protection: Patented cable technology blocks internal liquid migration, ensuring oil cannot escape through the core of the probe's lead.
• Completely Threaded Case: A 3/8-24 UNF threaded body with an overall case length of 4.1 inches and 0.0 inches unthreaded.
• Unarmored Design: Compact, non-armored body (without armor option) suitable for clean installations and conduit runs.
• Gold-Plated ClickLoc Connector: Miniature coaxial ClickLoc connector offers a robust, vibration-resistant connection with a simple finger-tight 'click' lock.
• Rugged System Integration: Employs TipLoc molding for an exceptionally strong bond between the 8 mm tip and the stainless steel body.
• Hazardous Location Approvals: Option 05 provides approvals for hazardous areas including ATEX, IECEx, and CSA.

Applications

The Bently Nevada 330101-00-41-15-12-05 is ideal for machine protection in extreme environments, including:

• Steam and gas turbine shaft vibration and axial position measurements.
• High-pressure compressor rotor displacement monitoring.
• Pumps and gearboxes where lubricating oil containment is crucial.
• Industrial rotating machinery requiring intrinsically safe instrumentation.

Installation Guidelines

To ensure proper function and safety when installing the 330101-00-41-15-12-05 proximity probe:

• Mounting Torque: Avoid over-tightening. The maximum recommended thread engagement is 0.563 inches for the 3/8-24 thread.
• Cable Management: Route the FluidLoc cable carefully to protect it from mechanical damage, keeping bend radii within specified limits.
• Probe Gap: Calibrate the physical gap according to the system specification (typically -10 Vdc bias at nominal center of range) for proper linear response.
• ClickLoc Connectors: Tighten only finger-tight until the connector clicks. Do not use wrenches or other tools, which can damage the miniature gold-plated contacts.

Compliance and Certifications

The Bently Nevada 330101-00-41-15-12-05 is approved for use in hazardous areas under Option 05:

• CSA: Intrinsically safe for Class I, Division 1 and 2, Groups A, B, C, and D.
• ATEX: Ex ia IIC T4/T5 Ga for explosive gas environments (Category 1G).
• IECEx: Internationally certified intrinsically safe Ex ia IIC Ga.
