Bently Nevada 330101-00-61-15-12-05 3300 XL 8 mm Proximity Probe

Description

The 330101-00-61-15-12-05 is a high-reliability, non-contact 3300 XL 8 mm proximity probe designed by Bently Nevada for industrial machinery protection and condition monitoring. This specific configuration is engineered with a 6.1-inch fully threaded stainless steel case (0.0-inch unthreaded length) and a total lead cable length of 1.5 meters (4.9 feet). A key differentiator for this variant is the integrated FluidLoc cable (option 12), which features a patented internal barrier to prevent turbine oil, synthetic lubricants, and other process fluids from leaking or migrating out of the machine housing through the interior of the coaxial cable. Built with a polyphenylene sulfide (PPS) molded tip and high-quality gold-plated ClickLoc connectors, this probe provides continuous shaft displacement, vibration, and speed measurement in severe operational environments. It is fully certified for explosive atmospheres under the -05 CSA, ATEX, and IECEx approvals package.

Features

• Molded 8 mm tip engineered from rugged polyphenylene sulfide (PPS) to withstand high temperatures and chemical exposure.
• FluidLoc cable construction prevents oil and moisture migration through the cable inner core, preserving pressure seals in wet machine environments.
• Extended 6.1-inch fully threaded case (0.0-inch unthreaded) provides optimal mounting depth flexibility in thick bearing housings.
• Gold-plated ClickLoc coaxial connector offers a secure, tool-free connection that clicks when locked to prevent loosening due to high-frequency vibration.
• Eddy-current operating principle delivers outstanding accuracy, temperature stability, and complete interchangeability without recalibration.
• CSA, ATEX, and IECEx approvals allow safe deployment in hazardous locations and explosive gaseous atmospheres.

Applications

• Steam and gas turbine rotor radial vibration and axial position measurement.
• Displacement and shaft movement tracking on centrifugal compressors and high-speed pumps.
• Fluid-film bearing oil casing installations where preventing oil leakage is crucial.
• Keyphasor speed, timing, and phase reference measurements.

Installation Guidelines

• Mount the probe with the correct probe gap (typically 1.27 mm or 50 mils) to match the calibrated linear range of the Proximitor sensor.
• Observe the maximum rated case torque of 11.2 N-m (100 in-lbf) during installation into standard threaded housings.
• Ensure the gold-plated ClickLoc connector is joined finger-tight until an audible click is felt; do not use pliers or other mechanical tools.
• Route the FluidLoc cable carefully to protect it from sharp edges, and maintain a minimum bend radius of 25.4 mm (1.0 in).

Compliance and Certifications

• CSA approvals: Certified for safe operation in Class I, Divisions 1 & 2, Groups A, B, C, and D hazardous environments.
• ATEX certifications: Compliant for use in Zone 0, Zone 1, and Zone 2 explosion-risk zones.
• IECEx certifications: Meets international requirements for hazardous area electrical equipment.
• RoHS: Compliant with European environmental restrictions.
