Description

The Bently Nevada 330101-00-43-10-02-05 is a high-precision 8 mm proximity probe designed for non-contact machinery vibration and shaft position measurements in critical rotating equipment. This specific configuration features a fully threaded 3/8-24 UNF steel body with 0.0 inches of unthreaded length, allowing it to be threaded directly into tapped holes without needing a clear bore. The 4.3-inch (109 mm) overall case length provides an extended mechanical reach, suitable for deeper bearing housings or thick machinery casings. It is supplied with a 1.0-meter (3.3 feet) unarmored coaxial cable terminated with a Miniature coaxial ClickLoc connector, and is fully certified for hazardous area operations under CSA, ATEX, and IECEx agency approvals.

Operating on the eddy-current principle, this probe continuously measures the distance between the sensor tip and the target shaft. When integrated within a complete 3300 XL transducer chain—consisting of the probe, a standard extension cable, and a 3300 XL Proximitor sensor—it outputs a highly accurate voltage signal directly proportional to the gap. This setup is key to identifying shaft vibration, radial displacement, and axial rotor position on steam turbines, gas turbines, heavy-duty compressors, and cooling pumps, supporting predictive maintenance and safeguarding critical plant assets.

Features

• 8 mm tip diameter engineered for highly reliable, non-contact eddy-current distance tracking.
• Fully threaded 3/8-24 UNF body (0.0 in unthreaded length) enables solid mounting along the entire case.
• Extended 4.3-inch (109 mm) case length accommodates mounting configurations requiring deep reach.
• Standard unarmored cable routing provides flexibility and is ideal for installation within protective conduits.
• Gold-plated Miniature coaxial ClickLoc connector ensures a secure, low-loss electrical connection to extension cabling.
• Polyphenylene sulfide (PPS) probe tip and AISI 303/304 stainless steel case resist extreme chemical and industrial environments.

Applications

• Continuous radial shaft vibration monitoring in steam and gas utility turbines.
• Axial thrust position tracking in heavy-duty industrial centrifugal compressors.
• Casing expansion and shaft displacement measurement on high-pressure water and petrochemical pumps.
• Condition monitoring and safety-critical protection on gearboxes, fans, and auxiliary rotating plant equipment.

Installation Guidelines

• Mount the probe into the bearing housing or casing thread, maintaining the standard recommended target gap (typically 1.27 mm / 50 mils for standard calibration systems).
• Ensure the maximum thread engagement does not exceed 14.3 mm (0.563 inches) to prevent physical binding during insertion.
• Observe the minimum bend radius of 25.4 mm (1.0 inch) during cable routing to prevent attenuation or damage to the triaxial conductor.
• Use standard plant conduit networks or cable clamps to route the unarmored cable, avoiding potential hot surfaces or high-voltage lines.

Compliance and Certifications

• CSA Class I, Division 1 and 2 Hazardous Areas (with Option 05)
• ATEX Zone 0, Zone 1, and Zone 2 explosive environments (with Option 05)
• IECEx certification for global explosive gas atmospheres (with Option 05)
