Bently Nevada 330101-00-68-10-12-05 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-68-10-12-05 is a high-performance 8 mm proximity probe engineered for non-contact shaft vibration and position measurements. As a specialized component of the 3300 XL 8 mm Proximity Transducer System, this configuration features a patented FluidLoc cable to prevent machine lubricating oil and other process fluids from leaking out of the machine housing through the inner core of the coaxial cable. Designed with a fully threaded 6.8-inch case (0.0 inches of unthreaded length) and a 1.0-meter total length, it provides exceptional measurement stability and mechanical longevity in heavy industrial environments. Armed with a miniature coaxial ClickLoc connector and certified for hazardous areas under ATEX, IECEx, and CSA standards, this probe is ideally suited for permanent installation on critical rotating machinery such as steam/gas turbines, centrifugal compressors, and high-pressure pumps.

Features

• Non-contact eddy-current technology provides continuous, highly accurate shaft displacement and position measurements.
• FluidLoc cable construction blocks oil and moisture propagation through the cable interior, protecting the terminal connection environment.
• PPS (polyphenylene sulfide) tip material molded into a stainless steel case for exceptional chemical, temperature, and wear resistance.
• Fully threaded 3/8-24 UNF body with an overall case length of 6.8 inches for deep-reach installation scenarios.
• Integrated gold-plated ClickLoc coaxial connector offers secure, vibration-resistant, finger-tight connections.
• Hazardous area approved (CSA, ATEX, IECEx) for intrinsic safety installations in explosive atmospheres.

Applications

• Steam and gas turbine shaft vibration and axial displacement monitoring
• Centrifugal compressor rotor position tracking and oil-seal protection
• Boiler feed pumps and high-pressure petrochemical pump shaft displacement
• Industrial gearboxes, electric motors, and generator bearing machinery protection

Installation Guidelines

• Mount the proximity probe using an appropriate probe gap per system calibration (typically gapped to output a nominal target voltage of -10 Vdc).
• Ensure the probe cable is routed away from high-power electrical interference and protected with conduit where mechanical damage is a risk.
• Ground the cable shielding properly at the Proximitor sensor end to minimize environmental electrical noise.
• Securely tighten the mounting lock nut to maintain proper gapping under persistent machinery vibration.

Compliance and Certifications

• ATEX: Ex ia IIC T5...T1 Ga (when paired with appropriate barriers)
• IECEx: Ex ia IIC T5...T1 Ga
• CSA: Intrinsic Safety approvals for hazardous environments
