This probe is part of the 3300 series, designed for harsh industrial environments. With a 1/4-28 UNF thread and a robust PPS tip, it ensures consistent performance even in demanding applications.
Technical Specifications of the 330171-00-08-10-02-CN
The Bently Nevada 330171-00-08-10-02-CN offers detailed specifications critical for system integration:
-
Power Supply: Requires -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. Operating beyond -23.5 Vdc may reduce linear range.
-
Output Resistance: 50 W (50 ohms) for standard load condition.
-
Probe DC Resistance: 7.59 ± 0.50 Ω for the 1.0 meter cable length (as configured).
-
Temperature Range: -35°C to +177°C for the probe, with specific temperature classifications for hazardous areas (see temperature schedule below).
-
Magnetic Field Susceptibility: At 60 Hz up to 300 Gauss, output voltage variation is minimal (e.g., at 50 mil gap, XL Proximitor Sensor output is 0.0131 mil pp/gauss).
-
Torque Limits: Probe case torque recommended 5.1 N·m, maximum 7.3 N·m. Connector-to-connector torque maximum 0.565 N·m.
-
Cable Bend Radius: Minimum 25.4 mm (1.0 in).
-
Weight: 0.323 kg.
Installation Guidance for Optimal Performance
Proper installation of the Bently Nevada 330171-00-08-10-02-CN is critical to avoid common failure modes such as thread stripping or misalignment. Follow these guidelines:
- Thread engagement: maximum 0.375 inches for the 1/4-28 UNF thread. Use a #3 or larger tap drill when drilling and tapping mounting holes.
- Apply recommended torque: 5.1 N·m (45 in·lb) for probe case, never exceed 7.3 N·m (65 in·lb) to prevent case damage.
- Ensure the probe cable has a minimum bend radius of 25.4 mm (1.0 in) to avoid cable fatigue.
- Use the miniature coaxial ClickLoc connector for secure connection. Torque to maximum 0.565 N·m.
Maintenance and Reliability Tips
Maintaining the 330171-00-08-10-02-CN involves regular inspection of cable integrity and connector tightness. The probe's temperature range (-35°C to +177°C) allows operation in extreme conditions, but avoid prolonged exposure below -34°C as it may cause pressure seal failure. The probe's robust construction with AISI 304 stainless steel case and PPS tip resists corrosion and wear, ensuring long service life. Periodic checks of torque values and magnetic field exposure will prevent drift.
Troubleshooting Common Issues
Common issues with proximity probes include signal noise due to magnetic fields or improper grounding. The Bently Nevada 330171-00-08-10-02-CN is designed to mitigate these effects; however, if output voltage variations occur, verify the probe gap and target material. Refer to the table for magnetic field effects at different gaps. For example, at 50 mil gap, the probe output is 0.0014 mil pp/gauss, indicating low susceptibility. Ensure the system power supply is within -17.5 Vdc to -26 Vdc and load is 10 kW as per specifications.
Selection Guide and Purchasing Advice
Before purchasing the Bently Nevada 330171-00-08-10-02-CN, verify your system requirements: cable length (1.0 meter), connector type (ClickLoc), and agency approval (CN). This probe is ideal for applications requiring high reliability in vibration monitoring, such as turbines, compressors, and pumps.
