Bently Nevada 330704-000-050-10-02-00 3300 XL 11 mm Proximity Probe

Description

Fully threaded M14 x 1.5 metric steel probe case with stainless steel armor (Option 000 unthreaded, Option 050 case length) defines the 330704-000-050-10-02-00, a ruggedized 3300 XL 11 mm Proximity Probe equipped with a 1.0 m standard coaxial cable and ClickLoc miniature coaxial connector without connector protector.

This eddy-current probe is used in fluid-film bearing monitoring systems, delivering non-contacting vibration and axial displacement measurements on critical rotating machinery. Operating with a 3.94 V/mm (100 mV/mil) output scale factor, its large 11 mm tip provides an extended 4.0 mm (160 mils) linear range, making it suitable for axial thrust position and ramp differential expansion measurements. The built-in flexible AISI 302 stainless steel armor protects the triaxial FEP-insulated cable against mechanical wear, abrasions, and harsh industrial environments. The probe integrates with a 3300 XL 11 mm extension cable and a 330780 Proximitor Sensor for an engineered transducer system configuration.

Installation Guidelines

• Target Calibration: System accuracy specifications apply when utilizing standard AISI 4140 steel targets.
• Gap Setting: Position the probe tip at a physical gap of 2.5 mm (100 mils) from the target surface for centered linear range performance.
• Torque Limits: For M14 x 1.5 metric cases, limit thread installation torque to the recommended 21.1 N-m (187 in-lb) to avoid binding. Do not exceed the maximum rated limit of 63.3 N-m (560 in-lb).
• Thread Engagement: Maintain thread engagement within maximum limits (typically 21 mm) to prevent physical thread stress.
• Cable Routing: Ensure minimum bend radius of 25.4 mm (1.0 in) is maintained along the armored lead route. Prevent mechanical tension on the cable-to-sensor junctions.
• Connector Protection: Ensure the miniature ClickLoc connector remains free of contaminants and fluids. Connector protectors or oil-resistant heat-shrink sleeves should be utilized if the connection is exposed to environments containing turbine oil.

Compliance and Certifications

• Agency Approvals (EE Option 00): No specialized hazardous area approvals are required or supplied for this specific configuration.
• Electromagnetic Compatibility (EMC): Meets industrial standards including European Community Directive 2014/30/EU, EN 61000-6-2 (Immunity), EN 61000-6-4 (Emissions).
• Environmental Directives: Compliant with European Union RoHS Directive 2011/65/EU and meets relevant China RoHS guidelines.
