Industry Applications
The 330905-00-13-05-02-05 excels in process compressor applications where chemical resistance is critical. It also suits general rotating machinery monitoring, including turbines, pumps, and fans, providing accurate shaft vibration and position data. Its superior side-view characteristics make it ideal for applications requiring precise gap settings.
Installation & Setup Guidance
Install the probe with finger-tight torque, then apply maximum 0.56 N•m (5 in•lb) for final seating. Ensure the target surface meets the minimum diameter requirements (8.9 mm flat target). For optimal linearity, set the gap to 1.0 mm (40 mils). Use three-conductor shielded triad cable for field wiring, maintaining a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and monitor.
Maintenance & Reliability
Periodically inspect the probe cable for bends exceeding the 25.4 mm minimum bend radius. Verify the O-ring seal integrity, especially in high-pressure applications. Regular calibration checks against the ISF tolerance help maintain measurement accuracy. The robust stainless steel case and PPS tip resist corrosion, extending service life in harsh environments.
Compatibility & Integration
The 330905-00-13-05-02-05 is fully compatible with Bently Nevada 3300 XL NSv Proximitor Sensors and monitors. It replaces older 3300 RAM probes without system modifications. The miniature coaxial ClickLoc connector ensures secure, quick connections with extension cables.
Selection Guide & Purchasing Advice
Before ordering, confirm your required thread size (M10X1), overall case length (130 mm), and total length (0.5 m). Verify the connector type (miniature coaxial ClickLoc) and agency approval options.
