Applications
The Bently Nevada 330905-00-15-05-02-00 is ideal for radial and axial position monitoring in turbomachinery, compressors, and pumps. Its increased chemical resistance makes it a preferred choice for process compressor applications where exposure to aggressive media occurs. The probe's stable side-view characteristics ensure accurate gapping even in tight installations, reducing measurement errors.
Installation & Setup
For optimal performance, install the probe with finger-tight torque, never exceeding 0.56 N•m (5 in•lb). Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable. Use three-conductor shielded triad cable for field wiring; the maximum length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). Ensure the target surface is flat and at least 8.9 mm (0.35 in) in diameter; for axial measurements on shafts smaller than 13 mm (0.5 in), expect scale factor changes—reduce the gap to minimize variation.
Maintenance & Reliability
Regularly inspect the probe tip for contamination or damage, as build-up can affect linearity. Verify cable integrity and connector tightness during routine maintenance. The PPS tip and stainless steel case offer excellent durability, but periodic checks ensure long-term accuracy. With proper care, this probe maintains its specified performance, reducing downtime and replacement costs.
Compatibility & Integration
The 3300 NSv probe is mechanically and electrically compatible with Bently Nevada's previous 3300 RAM system, allowing direct replacement. It works seamlessly with 3300 XL NSv Proximitor Sensors and standard monitoring systems. The miniature coaxial ClickLoc connector simplifies installation and ensures secure connections.
