Bently Nevada 330104-00-10-10-02-00 3300 XL 8mm Proximity Probe

Description

The Bently Nevada 330104-00-10-10-02-00 is a high-performance, metric-threaded 3300 XL 8 mm Proximity Probe supplied with stainless steel armor, designed as a core component of the 3300 XL 8 mm Proximity Transducer System. Operating on eddy-current principles, the system provides an output voltage directly proportional to the static or dynamic distance between the probe tip and an observed conductive target surface, typically AISI 4140 steel. It provides precision static position measurements for axial thrust or thermal expansion, and dynamic measurements for fluid-film bearing vibration monitoring, speed tracking, and Keyphasor references.

This standard 8 mm proximity probe features a rugged polyphenylene sulfide (PPS) tip molding that encapsulates the internal probe coil via a patented TipLoc design, delivering extreme physical durability and structural integrity in harsh industrial environments. The body is constructed from premium AISI 303 or 304 stainless steel and incorporates a patented CableLoc junction providing up to 330 N (75 lbf) of pull strength to eliminate cable detachment risks. Equipped with a gold-plated miniature coaxial ClickLoc connector, the probe enables reliable, tool-free finger-tight connections that lock into place to prevent accidental loosening under machine vibration. The 330104-00-10-10-02-00 is natively matched to provide accurate proximity data in critical machinery across power generation, oil and gas processing, and heavy industrial rotating machinery applications.

Features

• API 670 Compliant Performance: The complete 5-metre transducer system fulfills all stringent mechanical configuration, linear range, accuracy, and temperature stability specifications of the American Petroleum Institute (API) 670 Standard.
• Interchangeable Design Architecture: Complete system components allow total interchangeability without individual component matching or manual bench recalibration.
• Patented TipLoc Molding Mechanism: Features a highly robust bond between the polyphenylene sulfide (PPS) probe tip and the stainless steel probe body for high-pressure sealing.
• Integrated CableLoc Pull-Strength: Delivers an exceptional 330 N (75 lbf) maximum rated pull strength between the probe case and the probe lead wire.
• Corrosion-Resistant ClickLoc Connector: Gold-plated brass or gold-plated beryllium copper connectors click when finger-tightened, ensuring a secure joint without extra tools.
• Flexible Stainless Steel Armor Protection: Features an integrated flexible AISI 302 or 304 stainless steel protective armor jacket with a fluoroethylene propylene (FEP) outer jacket for maximum mechanical routing security.
• Backward System Compatibility: Seamlessly interchangeable and backward compatible with standard non-XL Bently Nevada 3300 series 5 mm and 8 mm proximity transducer system configurations.

Applications

• Fluid-Film Bearing Machinery: Radial vibration monitoring and axial position tracking on high-speed turbines, compressors, and pumps.
• Hydroelectric and Steam Turbines: Large rotating shaft displacement and absolute casing expansion analysis.
• Keyphasor and Phase Reference System: Delivers accurate once-per-turn timing pulses for vibration phase analysis and absolute rotational speed acquisition.

Installation Guidelines

• Probe Gap Adjustment: Ensure that during installation, the mechanical distance between the PPS tip and the rotating shaft is set exactly using a feeler gauge to 1.27 mm (50 mils) to establish a voltage gap reading of approximately -10 Vdc at the center of the linear profile.
• Thread Engagement Torque: Tighten the M10 x 1 metric thread case to the recommended torque level of 7.5 Nm (66 in-lbf). Do not exceed the maximum rated ceiling of 22.6 Nm (200 in-lbf) to prevent casing damage.
• Cross-Talk Minimization: Maintain a minimum separation distance of at least 40 mm (1.6 in) for axial position layout measurements or 38 mm (1.5 in) for radial displacement installations to hold cross-talk below 50 mV.
• Connector Tightening Protocol: Connectors must be joined finger-tight until an audible "click" is felt. If joining a non-XL stainless steel connector with a 3300 XL style connector, use pliers to tighten finger tight plus an additional 1/8 turn up to a maximum torque limit of 0.565 Nm (5 in-lbf).
• Moisture and Oil Protection: Use the provided connector protectors for every installation. Apply silicone tape only in non-oil environments, avoiding locations directly exposed to aggressive turbine lubricants.

Compliance and Certifications

• CE Mark Directive: Fully complies with standard European CE mark guidelines for industrial instrumentation.
