Product Overview
The Bently Nevada 330905-00-08-10-02-CN is a 3300 NSv proximity probe designed for precise vibration and position monitoring in rotating machinery. This industrial automation module features an M10X1 thread, a 1.0-meter (39-inch) total length, and a miniature coaxial ClickLoc connector with standard cable. It is mechanically and electrically compatible with previous 3300 RAM probes, offering enhanced chemical resistance for demanding process compressor applications.
With a linear range of 1.5 mm (60 mils) and an incremental scale factor of 7.87 V/mm (200 mV/mil), this probe delivers reliable, accurate measurements. Its robust construction—polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case—ensures durability in harsh environments.

Industry Applications
The 330905-00-08-10-02-CN is ideal for vibration monitoring on turbines, compressors, pumps, and motors. Its superior side-view characteristics improve gapping accuracy, making it a preferred choice for axial position and radial vibration measurements. In chemical processing plants, the probe's increased chemical resistance ensures reliable performance even in aggressive media.
Installation & Setup Guidance
For optimal performance, mount the probe with finger-tight torque and avoid exceeding 0.56 N•m (5 in•lb). Ensure the target surface is flat and meets the minimum diameter of 8.9 mm (0.35 in); for best results, use a target of at least 13 mm (0.5 in). The recommended gap setting is 1.0 mm (40 mils). When routing the cable, maintain a minimum bend radius of 25.4 mm (1.0 in) to prevent damage.
Compatibility & Integration
This probe works seamlessly with Bently Nevada 3300 XL NSv Proximitor Sensors and monitors. Field wiring should use a three-conductor shielded triad cable with a maximum length of 305 meters (1,000 feet) between sensor and monitor. The probe is compatible with standard Bently Nevada extension cables featuring ClickLoc connectors.
Selection Guide & Purchasing Advice
Before ordering, verify your system's thread type (M10X1) and total length requirements. The -00-08-10-02-CN configuration indicates a 0 mm unthreaded length, 80 mm overall case length, and 1.0 meter cable. For trusted sourcing, PLC Source PRO offers new, original units with full factory warranty.
