Description
The Bently Nevada 330901-00-08-10-02-CN is a high-performance 3300 NSv (Near-Switch) proximity probe designed for precision vibration and position monitoring in constrained environments. This transducer system is engineered specifically for applications where standard 5 mm or 8 mm probes cannot be utilized due to side-view, rearview, or counter-bore restrictions.
Features
- Optimized for tight installation requirements and small target applications.
- Standard scale factor of 7.87 V/mm (200 mV/mil).
- Equipped with a miniature coaxial ClickLoc connector for secure, reliable signal transmission.
- Designed for compatibility with fluid-filmed bearing machinery.
- Supports integration with Bently Nevada condition monitoring platforms.
Applications
This probe is ideal for small-diameter shafts (less than 51 mm / 2 in) and small flat targets (less than 15 mm / 0.6 in). Common industrial applications include:
- Radial vibration and position measurements.
- Axial (thrust) position monitoring.
- Tachometer and zero-speed sensing.
- Phase reference (Keyphasor) signal acquisition.
- Health monitoring for centrifugal compressors, steam/gas turbines, pumps, and gearboxes.

Installation Guidelines
- Ensure the probe is mounted in a secure, vibration-free bracket to prevent false signal noise.
- Use caution when tightening the 1/4-28 UNF thread; do not exceed torque specifications to avoid damaging the probe casing.
- Maintain proper clearance from the target to ensure the probe operates within its linear range (typically starting 0.25 mm from the target).
- Route coaxial cables away from high-voltage power lines and sources of electromagnetic interference (EMI).
- Verify that the Proximitor sensor impedance matches the NSv probe requirements before system power-up.
FAQ
What is the primary purpose of the 330901 NSv probe?
It is designed for machinery where conventional probes are too large, specifically for small-diameter shafts or constrained spaces where side-view clearance is limited.
Is this probe interchangeable with standard 3300 XL 8mm probes?
No. The NSv system requires a dedicated NSv Proximitor sensor due to different impedance characteristics and is not directly interchangeable with standard 3300 XL 8mm components.
Does this probe require special handling?
Yes, as a precision measurement device, the probe tip must be kept clean and free of debris. Ensure the ClickLoc connector is fully seated to maintain signal integrity.
