Product Overview
The Bently Nevada 330905-00-13-10-01-05 is a 3300 NSv proximity probe engineered for precise shaft vibration and position monitoring in critical rotating machinery. This industrial automation module delivers reliable performance in process compressor applications, where chemical resistance and accurate gap measurement are essential.
This probe is mechanically and electrically compatible with previous 3300 RAM models, enabling straightforward upgrades. Its side-view characteristics outperform the 3000-series 190 probe, providing more consistent readings when gapping at the same target distance.

Performance and Reliability
The 330905-00-13-10-01-05 provides a deviation from best fit straight line (DSL) of less than ±0.06 mm (±2.3 mils), ensuring accurate displacement measurement over the full linear range. With a recommended gap setting of 1.0 mm (40 mils), this probe is optimized for standard rotating machinery clearance.
Its increased chemical resistance compared to the 3300 RAM probe makes it ideal for harsh process environments. The Viton O-ring seal prevents differential pressure leakage between the probe tip and case.
Installation Guidance
Mount the probe with finger-tight torque; maximum recommended torque is 0.56 N•m (5 in•lb). For M10x1 threads, use a maximum of 22.6 N•m (200 in•lb) rated torque, but recommended is 7.5 N•m (66 in•lb). Ensure the minimum bend radius of 25.4 mm (1.0 in) for the cable is respected to avoid damage.
When routing field wiring, use a three-conductor shielded triad cable with a maximum length of 305 meters (1,000 feet) between the 3300 XL NSv Proximitor Sensor and the monitor. This ensures optimal frequency response and signal integrity.
Applications
This proximity probe suits a wide range of turbomachinery, including compressors, pumps, and turbines. In process compressor applications, the 330905-00-13-10-01-05 delivers stable readings despite chemical exposure. Its side-view characteristics also improve accuracy when measuring axial position on shafts smaller than 13 mm (0.5 in) diameter.
For vibration monitoring on large rotating equipment, the probe provides a linear range starting at 0.25 mm from the target, enabling early detection of shaft misalignment or bearing wear.
Selection Guide
Before purchasing, verify your required unthreaded length, overall case length, and total cable length. The 330905-00-13-10-01-05 features a 00 mm unthreaded length, 130 mm overall case length, and 1.0 meter total length. It uses a miniature coaxial ClickLoc connector with connector protector and standard cable.
Ensure your monitoring system is compatible with the 3300 NSv series. PLC Source PRO supplies this new, original factory-packed unit with a 12-month warranty, ensuring reliable operation for your critical assets.
