Bently Nevada 330905-00-10-05-02-CN 3300 NSv Proximity Probe

The Bently Nevada 330905-00-10-05-02-CN serves as the primary 3300 NSv Proximity Probe utilized to execute shaft vibration and position measurement across 3300 NSv Proximity Transducer System platforms.

Hardware Specifications

Rotor Dynamics & Eddy-Current Probe Scaling

The 330905-00-10-05-02-CN proximity probe generates a high-frequency RF field from its compact 5 mm sensing tip to track dynamic shaft behavior in restricted clearance envelopes. Precision eddy-current probe scaling delivers a nominal scale factor of 7.87 V/mm across a 0.25 mm to 2.0 mm linear dynamic range. Standard field calibration utilizes gap voltage validation targeting nominal -10 VDC offsets at the midpoint of travel. This architecture minimizes cross-talk suppression issues during close-proximity mounting on small rotating machinery shafts, delivering stable voltage output transitions between -4 VDC and -20 VDC.

Frequently Asked Questions

Q: What is the primary physical design advantage of the 3300 NSv probe over standard 8 mm probes?

A: The compact 5 mm sensing tip and M10 x 1 body allow installation in tight clearance spaces where standard 8 mm probes cannot physically fit due to side-wall clearance constraints.

Q: Does the 330905-00-10-05-02-CN probe require field recalibration when connected to a 3300 NSv Proximitor?

A: No, the probe matches the fixed electrical length and transfer function of the 3300 NSv Proximitor sensor directly, allowing plug-and-play installation without field recalibration.

Field Installation Guidelines

• Thread the probe body into the M10 x 1 port, ensuring a minimum of 5 full thread turns to maintain structural mounting rigidity.
• Set the mechanical gap by monitoring the Proximitor output voltage with a digital multimeter until the target -10 VDC gap setting is reached.
• Torque all mounting lock nuts to specified engineering limits to prevent probe drift under severe machinery vibration.
• Protect coaxial cable connections using weatherproofing boots or terminal enclosures to preserve the IP67 ingress rating.
