Product Overview
The Bently Nevada 330903-00-05-05-02-00 is an industrial automation module designed for precise proximity measurement in rotating machinery. This 3300 NSv probe features an M8X1 thread, a 0.5-meter cable, and a miniature coaxial ClickLoc connector. It is a direct replacement for the earlier 3300 RAM probe, offering improved chemical resistance for demanding process compressor applications.
With a linear range of 1.5 mm and an incremental scale factor of 7.87 V/mm, the 330903-00-05-05-02-00 delivers reliable vibration and position data to protect critical assets.

Applications
The 330903-00-05-05-02-00 is ideal for radial and axial position monitoring in turbines, compressors, pumps, and other rotating equipment. Its enhanced chemical resistance makes it suitable for process compressor applications where exposure to aggressive media is common. The probe provides accurate gap measurements for machinery protection and condition monitoring systems.
Thanks to its superior side-view characteristics, this module delivers consistent readings even when the probe is gapped at the same distance as older models, simplifying retrofits.
Installation and Setup
Install the Bently Nevada 330903-00-05-05-02-00 by threading it into a properly prepared mounting hole. Use the recommended torque of 5.1 N·m (45 in·lb) for the probe case; do not exceed 7.3 N·m (65 in·lb). Finger-tighten the connector and avoid over-torquing. Ensure the cable bend radius does not exceed 25.4 mm to prevent damage.
For field wiring, use a three-conductor shielded triad cable with 0.2 to 1.5 mm² (16 to 24 AWG) conductors. The maximum cable length between the Proximitor Sensor and the monitor is 305 meters (1000 feet).
Maintenance and Reliability
Routine inspection should focus on the probe tip and cable for signs of wear or chemical attack. The NSv design offers improved chemical resistance, reducing maintenance frequency in harsh environments. Verify the probe's DC resistance periodically to ensure it remains within tolerance (4.0 ± 0.5 ohms). If the resistance drifts, check cable integrity and connector tightness.
Operating and storage temperature ranges of -52°C to +177°C allow use in extreme conditions, but prolonged exposure to temperatures near the upper limit may accelerate aging of the PPS tip.
Selection and Purchasing Advice
When ordering this module, confirm the exact part number 330903-00-05-05-02-00 to match your application requirements. Verify thread size, overall length, and connector type. For assistance with compatibility or custom pressure testing, consult the manufacturer's guidelines.
