Applications
The Bently Nevada 330905-05-13-10-12-05 is engineered for critical machinery monitoring in industries such as oil & gas, power generation, and chemical processing. Its enhanced chemical resistance makes it particularly suitable for process compressors where exposure to aggressive media is common. The probe's superior side-view characteristics ensure accurate gap measurements, reducing the risk of misalignment and improving overall machine reliability. Whether used in turbomachinery, pumps, or motors, this probe delivers dependable data for predictive maintenance programs.
Installation & Setup
Proper installation is crucial for optimal performance. Follow these guidelines:
- Mount the probe with the M10x1 thread, ensuring the case threads engage at least 15 mm but do not exceed recommended torque (7.5 N•m or 66 in•lb).
- Use the recommended torque for the probe case: finger tight initially, then apply maximum 0.56 N•m (5 in•lb) for the connector.
- Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable to prevent damage.
- Set the recommended gap to 1.0 mm (40 mils) using the linear range starting at 0.25 mm (10 mils) from the target.
- For field wiring, use a three-conductor shielded triad cable with cross-section 0.2 to 1.5 mm² (16 to 24 AWG). Keep total cable length under 305 meters (1000 feet) to avoid signal rolloff.
Maintenance & Reliability
The 330905-05-13-10-12-05 is built for long service life, but regular inspection ensures continued accuracy. Check the probe tip and cable for signs of wear or chemical attack, especially in harsh environments. Verify the connector torque periodically to avoid loosening due to vibration. The Viton O-ring provides a reliable pressure seal, but if your application requires pressure testing, contact our custom design department. With proper care, this probe minimizes downtime and reduces total cost of ownership.
Buying Guide
When ordering the Bently Nevada 330905-05-13-10-12-05, verify the following: unthreaded length (50 mm), overall case length (130 mm), total length (1.0 m), and connector type (miniature coaxial ClickLoc). Ensure your monitoring system is compatible with the 3300 NSv series. PLC Source PRO offers this new, original unit with a 12-month factory warranty, backed by fast worldwide shipping.
