Product Overview
When process compressor applications demand reliable vibration monitoring in harsh chemical environments, the Bently Nevada 330907-05-30-10-12-CN 3300 NSv Reverse Mount Probe delivers the performance you need. This industrial automation module is engineered for side-view proximity sensing, offering superior gap measurement accuracy compared to earlier probe designs.
The 330907-05-30-10-12-CN features M10X1 threads, a 1.0 meter (39 inches) total length, and a miniature coaxial ClickLoc connector with FluidLoc cable. Its country-specific agency approval (CN) ensures compliance for your region. Built in the U.S.A., this probe is part of the trusted 3300 NSv series, designed for demanding machinery monitoring.
Key Technical Specifications
The 330907-05-30-10-12-CN provides precise, repeatable measurements across a defined linear range. Below are the critical parameters you can rely on:
-
Linear Range: 1.5 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target, extending to 1.75 mm (70 mils) with output from -1 to -13 Vdc.
-
Recommended Gap Setting: 1.0 mm (40 mils).
-
Probe DC Resistance: 4.2 ± 0.5 ohms (for 1.0 meter length).
-
Operating & Storage Temperature: -52°C to +177°C (-62°F to +351°F).
-
Probe Tip Material: Polyphenylene sulfide (PPS).
-
Probe Case Material: AISI 304 stainless steel (SST).
Performance and Design Advantages
The 330907-05-30-10-12-CN offers increased chemical resistance compared to the 3300 RAM probe, making it ideal for process compressor environments. Its side-view characteristics outperform the 3000-series 190 probe when gapping at the same distance from the target.
All transducer system components feature gold-plated brass ClickLoc connectors that lock securely, preventing loosening. The patented TipLoc molding method ensures a robust bond between the probe tip and body, enhancing durability and measurement stability.
Installation and Setup Guidance
For reverse mount probes, tighten to a maximum torque of 22.6 N·m (200 in·lb), with a recommended torque of 7.5 N·m (66 in·lb). The M10x1 thread requires a maximum engagement length of 15 mm. Ensure the probe tip is clean and properly positioned to achieve the recommended gap setting of 1.0 mm (40 mils).
Field wiring should 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 Proximitor Sensor and the monitor.
Maintenance and Reliability
The 330907-05-30-10-12-CN is designed for long-term reliability. The Viton O-ring seals against differential pressure between the probe tip and case. Avoid sustained exposure to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. Routine inspection of the probe tip and connector integrity will ensure consistent performance.
Compatibility and Integration
This probe is compatible with the 3300 XL NSv Proximitor Sensor system. It is designed for use with Bently Nevada monitoring systems that accept eddy-current proximity probes. The ClickLoc connector ensures a secure connection to extension cables and Proximitor sensors.
Selection Guide and Purchasing Advice
Before purchasing, verify your application's thread type, length, and connector requirements. The 330907-05-30-10-12-CN is a reverse mount probe with M10X1 threads, 1.0 meter length, and a miniature coaxial ClickLoc connector with FluidLoc cable. This model is ideal for process compressors and similar applications where chemical resistance is critical.
