Bently Nevada 330104-00-10-20-12-05 3300 XL 8 mm Reverse Mount Proximity Probe

Description

330104-00-10-20-12-05: 3300 XL 8 mm reverse mount proximity probe, 3/8-24 UNF thread, 1.0 inch case length, 2.0 meter total system length, standard cable with connector protector, and CSA/ATEX/IECEx hazardous area approvals. This sensor is designed for non-contact eddy-current displacement measurement, serving as a component within 3300 XL 8 mm monitoring chains to measure shaft vibration and axial position on critical rotating machinery.

The 330104 series features a reverse mount configuration, allowing the probe to be installed through the machine case or a bearing housing where the connector is positioned on the exterior, protecting the connection from process fluids. This configuration differs from standard 330101 probes by the absence of a thread adjustment nut on the exterior, utilizing a fixed installation design. This specific unit includes a factory-installed connector protector (Option 12), which provides environmental sealing and mechanical protection for the coaxial cable interface.

Features

• 8 mm probe diameter compatible with 3300 XL Proximitor sensors
• Reverse mount installation design for specific machine housing requirements
• Standard cable construction with connector protector (Option 12)
• 2.0 meter system length (Option 20)
• CSA, ATEX, and IECEx hazardous area approvals (Option 05)
• Fully threaded 3/8-24 UNF steel body (Option 00)

Applications

• Turbine-generator shaft vibration monitoring
• Compressor rotor position and axial displacement
• Fluid film bearing health monitoring
• Critical machinery protection in petrochemical and power generation environments

Installation Guidelines

Ensure the probe is installed in a rigid bracket or housing to prevent vibration-induced measurement errors. For reverse mount configurations, verify the probe tip extends the appropriate distance into the machine cavity to maintain the required gap (typically 1.27 mm nominal). The probe coaxial cable must be routed away from high-voltage lines and secured to prevent chafing. Use the included connector protector to seal the cable interface against moisture and contaminants in external installations.

Compliance and Certifications

This product meets the requirements for hazardous area installation under CSA, ATEX, and IECEx directives for the classifications specified in the 3300 XL documentation suite. Ensure local electrical codes are followed regarding grounding and barrier requirements for intrinsically safe loops.
