Product Introduction
Vibration monitoring in rotating machinery demands precise and durable proximity probes. The Bently Nevada 330709-016-240-50-02-00 3300 XL 11 mm Proximity Probes offer reliable measurement with robust construction. This probe features a 5.0 meter total length, M16 x 1.5 thread, and a miniature coaxial ClickLoc connector. Designed for demanding industrial environments, it ensures accurate shaft vibration and position data for predictive maintenance and machine protection.
Technical Specifications Breakdown
The following key specifications define the performance of the Bently Nevada 330709-016-240-50-02-00 3300 XL 11 mm Proximity Probes:
-
Probe Length: 5.0 meters (16.4 feet) – designed exclusively for use with the 5-meter Proximitor Sensor.
-
DC Resistance (RPROBE): 7.2 ± 0.8 ohms from center conductor to outer conductor.
-
Temperature Range: Operating and storage -52°C to +177°C (-62°F to +351°F).
-
Probe Tip Material: Polyphenylene sulfide (PPS) for chemical resistance.
-
Probe Case Material: AISI 304 stainless steel (SST) for corrosion resistance.
-
Probe Case Torque: Recommended 21.1 N·m (187 in·lb); maximum 63.3 N·m (560 in·lb).
-
Cross-talk Limitation: Minimum flat target diameter 30.5 mm (1.2 in); minimum shaft diameter 152 mm (6.0 in).
-
60 Hz Magnetic Field Effect: Output variation measured at specific gaps (e.g., at 0.5 mm gap: 0.001 V pp/Gauss).
-
Connector: Miniature coaxial ClickLoc, standard cable.
Troubleshooting & Common Issues
Common failure modes in proximity probes include signal interference and environmental damage. The Bently Nevada 330709-016-240-50-02-00 3300 XL 11 mm Proximity Probes address these with specific design parameters. The recommended minimum target and shaft diameters prevent cross-talk between adjacent probes. The wide temperature range and 100% condensing humidity rating (non-submersible with protected connectors) reduce risk of seal failure. Proper torque application is critical: use recommended torque of 21.1 N·m on the probe case to avoid thread damage, and finger-tight torque (max 0.565 N·m) on the connector. The minimum bend radius of 25.4 mm protects the cable from stress fractures.
Installation & Setup Guidance
Correct installation ensures optimal performance of the Bently Nevada 330709-016-240-50-02-00 3300 XL 11 mm Proximity Probes. Thread engagement should not exceed 24 mm on M16x1.5 threads. Use a torque wrench set to recommended values. The flexible cable (75 Ω triaxial FEP insulated) should be routed with a minimum bend radius of 25.4 mm (1.0 in). Ensure the probe tip is clean and free from debris. For systems using the 5-meter Proximitor Sensor, verify cable length compatibility. The miniature coaxial ClickLoc connector provides a secure connection without special tools.
Compatibility & Integration
The Bently Nevada 330709-016-240-50-02-00 3300 XL 11 mm Proximity Probes are designed for seamless integration with Bently Nevada monitoring systems. The 5.0 meter probe length is paired specifically with the five-meter Proximitor Sensor (sold separately). The standard cable and ClickLoc connector are compatible with Bently Nevada extension cables and panel feed-through systems. No additional adapters are required for typical rack-based monitoring systems like the 3500 or 3300 series.
Selection Guide & Purchasing Advice
When selecting the Bently Nevada 330709-016-240-50-02-00 3300 XL 11 mm Proximity Probes, verify system requirements: confirm probe length (5.0 m), thread type (M16 x 1.5), and connector (miniature coaxial ClickLoc). This model is non-armored; if armored probe is needed, consider other options. For replacement applications, ensure the existing Proximitor Sensor matches the 5-meter length.
