Global PLC Spare HUB's Insight

• The Bently Nevada 330905-00-03-10-01-00 is our top recommendation for radial vibration monitoring on small-diameter shafts.
• Its design allows it to be gapped at the same distance as larger probes while maintaining a linear signal.
• The 330905-00-03-10-01-00 is electrically interchangeable with the previous 3300 RAM series, simplifying legacy system upgrades.
• We advise using the included connector protector to prevent signal contamination from oil or moisture in the junction box.

Target Equipment & Application Scenarios

• Core Equipment: High-speed centrifugal compressors, small radial bearings, and turbo-expanders.
• Measurement Types: Shaft vibration, axial thrust position, and tachometer speed sensing.
• Industrial Use: Oil and gas refining, chemical processing, and power generation turbines.

Selection Comparison & Technical Advice

• Standard Version: 330905-00-03-10-01-00 (Optimized for global projects and standard inventory).
• CN Version: 330905-00-03-10-01-CN (Certified specifically for the China market with local compliance).
• Technical Suggestion: For shaft diameters smaller than 13mm, always perform a loop calibration to verify the scale factor accuracy.

• Warranty: 12-Month Factory Warranty.
• Processing: Ships within 24 to 48 hours.
• Express Shipping: Worldwide delivery via FedEx, UPS, or DHL.

Professional FAQ

• What is the primary advantage of the 3300 NSv over the older 3000-series 190 probe?
• The 330905-00-03-10-01-00 has much smaller "side-view" characteristics, allowing it to ignore nearby metal and focus only on the target.
• Does the 330905 probe come pressure tested from the factory?
• While designed to seal differential pressure via a Viton O-ring, they are not pressure tested prior to shipment unless specifically requested.
• What is the maximum field wiring length allowed for the 330905-00-03-10-01-00?
• You can run up to 305 meters (1,000 feet) of field wiring between the Proximitor sensor and the monitoring rack.
• Can I install this probe without a torque wrench?
• For the connector, finger-tight is recommended. For the case, we strongly advise using a torque wrench to meet the 11.3 N•m specification.
• Is the cable on the 330905-00-03-10-01-00 resistant to oil?
• Yes, the FEP-insulated coaxial cable is specifically designed to withstand exposure to most industrial lubricants and chemicals.
