Bently Nevada 330101-00-57-10-02-05 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-57-10-02-05 is a high-precision, non-contact 8 mm Proximity Probe belonging to the industry-standard 3300 XL machinery protection series. This specific configuration features a fully threaded 5.7-inch (145 mm) stainless steel case with no unthreaded portion (0.0-inch unthreaded length), enabling maximum depth adjustability during installation. Designed to be coupled with a 3300 XL extension cable and Proximitor sensor, this 1.0-meter probe plays a critical role in non-contact vibration and shaft position measurements. It is engineered without mechanical armor protection and incorporates a standard ClickLoc coaxial connector. With option 05 agency approval, this proximity probe complies with ATEX, IECEx, and CSA standards for use in explosive and hazardous industrial environments.

Features

• Rugged 8 mm tip diameter optimized for non-contact eddy-current displacement measurement.
• Fully threaded stainless steel body (0.0 in unthreaded length) allows maximum flexibility and fine-tuning of the probe gap.
• Extended 5.7-inch (145 mm) case length is ideal for deeper mechanical recesses, thick bearing housings, and sleeve-mounting.
• Features a standard, high-performance FEP-insulated triaxial cable (1.0 meter total length) without mechanical armor.
• Equipped with a gold-plated miniature coaxial ClickLoc connector providing secure connection feedback.
• Certified with the 05 approval option, meeting CSA, ATEX, and IECEx hazardous area safety requirements.
• Interchangeable with other standard 3300 XL components, preserving consistent system calibration.

Applications

• Steam and gas turbine shaft vibration and radial position monitoring.
• Thrust position and axial displacement measurements in critical rotating machinery.
• Centrifugal compressor, expander, and industrial pump shaft protection.
• Bearing oil film thickness and relative casing vibration analysis.
• Severe-duty industrial machinery monitoring in petrochemical, power generation, and refining plants.

Installation Guidelines

Proper installation of the proximity probe is critical to system performance and accuracy. Mount the probe securely in its bracket or bearing casing, ensuring the probe gap is set to the correct operating voltage (typically -9 Vdc or approximately 1.27 mm / 50 mils for radial vibration applications). Do not exceed the maximum rated thread torque of 33.9 N-m (300 in-lbf) during installation; the recommended mounting torque is 11.2 N-m (100 in-lbf) to prevent casing damage. Ensure that the gold ClickLoc connectors are connected finger-tight. Observe the minimum cable bend radius of 25.4 mm (1.0 in) during cable routing. Ground and shield all cables appropriately per Bently Nevada installation standard practices to avoid electromagnetic interference.
