Product Overview
The Bently Nevada 330907-05-30-05-12-00 is a 3300 NSv Reverse Mount Probe designed for demanding process compressor applications. This industrial automation module provides superior chemical resistance compared to the 3300 RAM probe and improved side-view characteristics over the 3000-series 190 probe. With M10X1 threads, a 0.5 meter (20 inch) total length, and a miniature coaxial ClickLoc connector with FluidLoc cable, the 330907-05-30-05-12-00 delivers reliable vibration and position monitoring in harsh environments.

Performance and Reliability
The 330907-05-30-05-12-00 uses gold-plated brass ClickLoc connectors that lock securely to prevent loosening. The patented TipLoc molding method ensures a robust bond between the probe tip and body. These features reduce the risk of connection failures and signal degradation, making the probe ideal for continuous operation in process compressors.
Installation and Field Wiring
For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) conductors, or 0.25 to 0.75 mm² (18 to 23 AWG) with ferrules. A three-conductor shielded triad cable is recommended, with a maximum length of 305 meters (1,000 feet) between the 3300 XL NSv Proximitor Sensor and the monitor. The probe case torque for reverse mount probes is rated at 22.6 N•m (200 in•lb) maximum and 7.5 N•m (66 in•lb) recommended. Ensure the M10x1 threads engage at least 15 mm for secure mounting.
Applications
This probe excels in process compressor applications where chemical resistance is critical. Its side-view characteristics make it suitable for measuring shaft vibration and position in turbomachinery, pumps, and other rotating equipment. The robust construction withstands extreme temperatures and pressures, ensuring accurate monitoring in challenging industrial environments.
Selection Guide
When selecting the Bently Nevada 330907-05-30-05-12-00, verify the thread type (M10X1) and total length (0.5m) match your installation requirements. Confirm the connector option (miniature coaxial ClickLoc) is compatible with your extension cable and Proximitor.
