Industry Applications
The 330905-00-13-05-02-CN excels in demanding environments where chemical resistance and reliable measurement are critical. Process compressor applications benefit from the NSv probe's enhanced chemical resistance compared to the 3300 RAM probe. In steam turbine monitoring, the probe's superior side-view characteristics allow accurate gap measurements even when space is limited. For axial position monitoring on shafts smaller than 13 mm, the recommended gap setting of 1.0 mm helps maintain scale factor stability. This Industrial Automation Module is also suitable for general rotating machinery protection systems, providing accurate vibration and displacement data essential for predictive maintenance.
Installation & Setup Guidance
Proper installation ensures optimal performance. Mount the probe with the recommended torque: finger tight for initial positioning, with a maximum torque of 0.56 N•m (5 in•lb). For the probe case, use the rated torque of 33.9 N•m (300 in•lb) maximum, or 11.3 N•m (100 in•lb) recommended. When routing the cable, maintain a minimum bend radius of 25.4 mm (1.0 in) to prevent damage. Field wiring should use a three-conductor shielded triad cable with 0.2 to 1.5 mm² (16 to 24 AWG) conductors; with ferrules, 0.25 to 0.75 mm² (18 to 23 AWG) is acceptable. The maximum field wiring length between the Proximitor Sensor and the monitor is 305 meters (1,000 feet). Ensure the probe tip is clean and free of debris before installation.
Maintenance & Reliability
Routine inspection of the probe and cable is essential for long-term reliability. Check the probe tip for wear or contamination, as this can affect measurement accuracy. The Viton O-ring seal maintains differential pressure integrity, but probes are not pressure-tested prior to shipment; if pressure testing is required, contact the custom design department. The probe's PPS tip and stainless steel case resist corrosion, extending service life in harsh environments. The cable's FEP insulation provides excellent chemical resistance, reducing the risk of failure. Regular calibration checks against the recommended gap setting of 1.0 mm (40 mils) help maintain measurement precision over time.
Compatibility & Integration
The 330905-00-13-05-02-CN is mechanically and electrically compatible with Bently Nevada's previous 3300 RAM proximity probe and extension cable, ensuring seamless upgrades. The miniature coaxial ClickLoc connector provides secure and reliable connections. This probe works with 3300 XL NSv Proximitor Sensors and supports field wiring lengths up to 305 meters (1,000 feet). Its frequency response of 0 to 10 kHz makes it suitable for most rotating machinery monitoring systems. The probe's compatibility with existing Bently Nevada systems simplifies integration into current vibration monitoring setups.
Selection Guide & Purchasing Advice
When ordering the 330905-00-13-05-02-CN, verify the unthreaded length (00 mm), overall case length (130 mm), total length (0.5 m), and connector type (miniature coaxial ClickLoc) to ensure it matches your application. Confirm the thread type (M10X1) is compatible with your mounting configuration. PLC Source PRO offers this product as new and original in factory packing, backed by a 12-month warranty.
