Key Benefits & Applications
This probe offers superior chemical resistance compared to earlier models, making it ideal for process compressor applications. Its side-view characteristics are enhanced, providing more accurate gapping at the same distance from the target. Typical applications include:
- Vibration monitoring on centrifugal and reciprocating compressors
- Shaft radial and axial position measurement in turbines
- Eccentricity monitoring in large electric motors
- Thrust bearing wear detection in pumps
Compatibility & Integration
The Bently Nevada 330903-00-05-05-01-05 is mechanically and electrically interchangeable with the previous 3300 RAM probe and extension cable. It works seamlessly with 3300 XL NSv Proximitor Sensors, ensuring a straightforward upgrade path. Field wiring recommendations include three-conductor shielded triad cable, with a maximum length of 305 meters (1,000 feet) between sensor and monitor.
Installation & Setup Guidance
For optimal performance, follow these guidelines:
- Mount the probe with finger-tight torque; do not exceed 0.56 N•m (5 in•lb).
- Maintain a recommended gap setting of 1.0 mm (40 mils) from the target.
- Ensure the target surface is flat and at least 13 mm (0.5 in) in diameter for accurate readings.
- Route the cable with a bend radius of at least 25.4 mm (1.0 in) to prevent damage.
- Use the specified field wiring (0.2 to 1.5 mm²) and keep connections clean and secure.
Maintenance & Reliability
Regular inspection of the probe tip and cable is recommended to ensure consistent measurements. The 3300 NSv design offers increased chemical resistance, reducing the risk of degradation in harsh environments. With proper installation and routine checks, this probe provides long-term reliability, minimizing downtime and maintenance costs.
Selection Guide & Purchasing Advice
When ordering, verify the thread type (M8x1), unthreaded length (00 mm), overall case length (50 mm), and total length (0.5 m) to match your application. The connector type (ClickLoc) and agency approvals (Multiple Approvals) are already configured for this part. For genuine, factory-sealed components with a 12-month warranty, consider PLC Source PRO as your trusted supplier.
