Product Overview
The Bently Nevada 330907-05-30-70-12-00 is a 3300 NSv Reverse Mount Probe designed for demanding industrial vibration monitoring. This industrial automation module offers superior chemical resistance compared to standard RAM probes, making it ideal for process compressor applications where exposure to aggressive media is common. Its side-view characteristics provide accurate gap measurements even when mounted at the same distance from the target as other probes.
With a 7.0-meter total length and M10x1 threads, the 330907-05-30-70-12-00 integrates seamlessly into existing 3300 XL monitoring systems. The miniature coaxial ClickLoc connector with FluidLoc cable ensures a secure, reliable connection that resists loosening. All transducer components feature gold-plated brass connectors for excellent conductivity and corrosion resistance.
Key Features & Benefits
-
Enhanced Chemical Resistance: The NSv probe withstands harsher environments than the 3300 RAM probe, extending service life in process compressors.
-
Superior Side-View Performance: Provides accurate readings even when gapped at the same distance as the 3000-series 190 probe.
-
Robust Construction: Probe tip material is polyphenylene sulfide (PPS), and the case is AISI 304 stainless steel for durability.
-
Secure Connections: ClickLoc connectors lock into place, preventing loosening, while the patented TipLoc molding ensures a robust bond between tip and body.
-
Wide Temperature Range: Operates from -52°C to +177°C (-62°F to +351°F), suitable for extreme industrial conditions.

Industry Applications
The 330907-05-30-70-12-00 excels in process compressor monitoring, where its chemical resistance prevents premature failure. It is also suitable for turbomachinery protection, pump vibration monitoring, and general rotating equipment in oil & gas, petrochemical, and power generation plants.
When upgrading from older 3300 RAM probes or 190 probes, the NSv offers improved reliability and easier installation, reducing downtime and maintenance costs.
Installation & Setup Guidance
For reverse mount probes, tighten to the recommended torque of 7.5 N•m (66 in•lb) — do not exceed the maximum rated torque of 22.6 N•m (200 in•lb). Ensure thread engagement does not exceed 15 mm to avoid damaging the probe. When routing field wiring, use a three-conductor shielded triad cable and keep the length under 305 meters to maintain signal integrity.
Maintenance & Reliability
Inspect the probe tip regularly for contamination or damage. Avoid sustained exposure to temperatures below -34°C (-30°F), which can compromise the pressure seal. The Viton O-ring sealing material provides reliable differential pressure sealing, but periodic checks are recommended in high-vibration environments.
Selection Guide & Purchasing Advice
Before ordering, verify your system requirements: confirm the thread type (M10X1), total length (7.0 m), and connector style (ClickLoc). Ensure compatibility with your 3300 XL Proximitor. For genuine Bently Nevada parts, trust PLC Source PRO for fast delivery and competitive pricing.
