Bently Nevada 330101-00-28-10-02-05 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-28-10-02-05 is a high-precision proximity probe engineered for non-contact shaft vibration and displacement measurements in rotating machinery. Part of the industry-proven 3300 XL 8 mm Proximity Transducer System, this eddy-current sensor delivers high reliability and linearity to companion 3300 XL Proximitor sensors. This specific configuration is distinguished by its completely threaded 2.8-inch case (0.0-inch unthreaded length), 1.0-meter total cable length, and standard miniature coaxial ClickLoc connector with unarmored standard cable. Certified with CSA, ATEX, and IECEx agency approvals, this probe is optimized for critical machinery protection programs in hazardous atmospheres, such as steam and gas turbines, high-pressure compressors, and turbine-generator sets.

Features

• Proximity probe with an 8 mm tip diameter optimized for eddy-current displacement measurements.
• Threaded 3/8-24 UNF-2A body style constructed without protective armor casing.
• Fully threaded 2.8 in overall case length with 0.0 in unthreaded length configuration.
• Standard 1.0-meter total cable length terminated with a gold-plated miniature coaxial ClickLoc connector.
• Equipped with hazardous area Option 05 agency approvals (CSA, ATEX, IECEx).
• Constructed with a polyphenylene sulfide (PPS) tip and AISI 303/304 stainless steel case for extreme environmental resistance.
• Electrically and physically interchangeable with older non-XL 3300 5 mm and 8 mm components.

Applications

• Steam turbine and gas turbine shaft vibration monitoring.
• Compressor and pump rotor dynamic displacement and axial thrust measurement.
• Machinery protection systems in oil and gas refineries, chemical plants, and power generation facilities.
• Critical rotating machinery installations in hazardous environments requiring ATEX or IECEx intrinsically safe certifications.

Installation Guidelines

• Mount the probe with the correct probe gap matching the specific calibration (typically 1.27 mm or 50 mils for standard systems).
• Observe a maximum thread engagement of 0.563 inches for the 3/8-24 UNF threads to prevent mechanical binding.
• Do not exceed the maximum rated installation torque of 33.9 N-m (300 in-lbf). Tighten to the recommended 11.2 N-m (100 in-lbf) torque using standard mounting practices.
• Ensure proper grounding and shielding procedures are followed per installation drawing 141092 during hazardous area mounting.
• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) during cable routing to prevent internal conductor damage.

Compliance and Certifications

• CSA certified for hazardous areas (Option 05)
• ATEX intrinsically safe and non-sparking zones (Option 05)
• IECEx certified for explosive gas and dust environments (Option 05)
• CE compliant
