Where It Excels in Industrial Use

• Compact Shaft Vibration and Position Monitoring:
The Bently Nevada 330905-05-10-10-12-05 is a 3300 NSv Proximity Probe designed for non-contact measurement of shaft displacement, radial vibration, and rotor position. It uses eddy-current sensing technology and is part of the 3300 XL NSv Proximity Transducer System.

• Small-Clearance Rotating Machinery Applications:
This probe uses an M10 × 1 metric thread and a non-armored construction, making it suitable for applications where installation space is limited. The 3300 NSv system is commonly used on centrifugal compressors, refrigeration compressors, process gas compressors, pumps, and other rotating equipment requiring compact shaft monitoring.

• FluidLoc Cable Configuration for Harsh Environments:
The -12 connector/cable option specifies a miniature coaxial ClickLoc connector with FluidLoc cable, helping prevent oil or fluid migration through the cable assembly and improving reliability in industrial installations.

• Machinery Protection and Predictive Maintenance:
When paired with a compatible 3300 XL NSv Proximitor Sensor and monitoring system, the probe provides shaft vibration and displacement signals used for machinery protection, alarm monitoring, and predictive maintenance.
