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.
