330701-00-26-10-11-CN 3300 XL 11mm Probe Bently Nevada

Product Overview

The Bently Nevada 330701-00-26-10-11-CN is an 11 mm eddy current proximity transducer probe belonging to the industry-standard 3300 XL series. Purpose-built for non-contact measurement of shaft vibration, axial position, and speed monitoring, this extended-range probe is designed for critical rotating machinery including steam turbines, heavy gas turbines, industrial compressors, and large gearboxes.

This specific part configuration (330701-00-26-10-11-CN) features a fully threaded 1/2-20 UNF stainless steel case, an overall case length of 2.6 inches, an integrated 1.0-meter (3.3 feet) FluidLoc coaxial cable equipped with ClickLoc miniature coaxial connectors and a connector protector, and China-specific (CN) hazardous area agency approvals. Weighing a total shipping weight of approximately 0.17 kg (0.37 lbs), the unit incorporates Viton® O-ring pressure sealing and operates reliably in extreme industrial environments from -51°C to +177°C (-60°F to +351°F).

Core Technical Advantages

• FluidLoc Cable Protection: Features an internal cable barrier that prevents oil and liquid ingress from traversing through the inside of the cable assembly.
• Extended Measurement Range: The larger 11 mm tip configuration provides a wider linear measurement range and larger clearance gaps compared to standard 8 mm probes.
• Secure ClickLoc Connection: Equipped with gold-plated ClickLoc miniature coaxial connectors and protective boots to maintain continuous signal continuity under harsh vibration.
• Hazardous Area Certified: Carrying China-specific (CN) agency approvals for seamless deployment in hazardous plant zones and localized compliance frameworks.

Technical Specifications

Installation & Gap Calibration Guide

• Mechanical Installation: Thread the 1/2-20 UNF probe body into the mounting bracket or housing. Tighten to the recommended torque of 15.2 N•m (133 in•lb), keeping within the maximum engagement depth of 0.750 inches.
• Gap Adjustment: Mechanically set probe clearance until the paired 3300 XL Proximitor Sensor output registers proper gap voltage according to system calibration curves.
• Connector Connection & Routing: Hand-tighten coaxial ClickLoc connectors (max 0.565 N•m), apply the connector protector over the joint, and observe the minimum bend radius limit of 25.4 mm (1.0 in).
