Description

The Bently Nevada 330101-00-71-05-01-05 is a high-performance 3300 XL 8 mm proximity probe engineered for precise, non-contact shaft vibration and position measurement in critical industrial machinery. This specific configuration features a fully threaded probe case with an unthreaded length of 0.0 inches and an overall case length of 7.1 inches featuring standard 3/8-24 UNF threads, lacking external mechanical armor. Designed for highly demanding condition monitoring chains, the unit provides a 0.5-meter (1.6-foot) standard coaxial cable terminated with a miniature ClickLoc connector and an integrated connector protector. The configuration is fully certified with CSA, ATEX, and IECEx approvals, ensuring safe operation within hazardous environments, distinguishing this assembly from uncertified variants or those with unprotected connectors.

Features

• Precise Eddy-Current Technology: Delivers reliable, non-contact measurement of radial shaft vibration, axial position, and speed.
• Fully Threaded Case: Features a 7.1-inch overall case length with 0.0-inch unthreaded length, allowing maximum thread engagement in 3/8-24 UNF mounts.
• Connector Protection: Coaxial cable terminated with a miniature ClickLoc connector including an integrated protector to shield against moisture, dust, and process fluids.
• Short Lead Configuration: Equipped with a 0.5-meter (1.6-foot) probe cable for compact routing to a nearby junction box or extension cable connection.
• Hazardous Area Approval: Decoded with agency approval code 05, certifying compliance with CSA, ATEX, and IECEx standards for explosion-proof and intrinsically safe environments.
• Unarmored Mechanical Style: Configured as a standard unarmored probe, minimizing outer diameter for clean routing inside conduits or protective enclosures.

Applications

• Steam and Gas Turbines: Dynamic shaft vibration and axial thrust position tracking in power generation plants.
• Compressor Rotor Displacement: High-reliability monitoring of radial shaft movement in petrochemical and pipeline compressors.
• Industrial Pump Shaft Protection: Monitoring shaft runout and thermal expansion in critical boiler feed and process pumps.
• Critical Rotating Machinery: Part of permanent machinery protection systems matching API 670 standards.

Installation Guidelines

• Probe Gap Setting: Mount the probe at the specified gap distance (typically 1.27 mm or 50 mils) to match the calibration curve of the 3300 XL system.
• Thread Engagement: Ensure proper thread engagement limits are respected during mounting. Avoid over-torquing the threaded probe case.
• Cable Routing: Route the standard coaxial cable away from high-temperature areas and sources of heavy EMI. Ensure there is minimal cable tension at the probe exit.
• Connector Care: The ClickLoc connector is equipped with an integrated connector protector. Ensure it is fully locked (finger-tight) to prevent moisture or lube oil ingress into the electrical junction.

Compliance and Certifications

• ATEX: Certification for Zone 0 / Zone 2 hazardous areas
• IECEx: Certification for explosive gas atmospheres
• CSA: Division 1 and Division 2 North American safety standards
