Industry Applications
The 330172-00-08-10-02-05 excels in monitoring shaft vibration and position in steam turbines, compressors, and pumps. In petrochemical plants, it detects early signs of bearing wear by measuring radial vibration. Its PPS tip withstands exposure to lubricants and process fluids, while the stainless steel case resists corrosion in offshore and refining environments. The probe’s sensitivity to magnetic fields (effects documented up to 300 Gauss) makes it suitable for integration with XL Proximitor sensors in existing Bently Nevada systems.
Installation & Setup Guidance
Proper mounting is critical for accurate readings. Use a #3 or larger tap drill when tapping a hole for the 1/4-28 thread. Maximum thread engagement is 0.375 in to avoid stress on the probe case. Apply the recommended torque of 5.1 N·m (45 in·lb) when tightening the probe case; do not exceed 7.3 N·m. For cable connectors, the max torque is 0.565 N·m (0.42 ft·lbf). Ensure the cable bend radius stays above 25.4 mm to prevent internal damage. When gapping the probe at 1.27 mm (50 mils), use a -24 Vdc power supply and 10 kΩ load for standard calibration.
Maintenance & Reliability
Regularly inspect the probe cable for cuts or abrasion, as the FEP insulation can degrade if exposed to temperatures below -34°C (-30°F). The probe temperature rating of -35°C to +177°C defines its safe operating window; exceeding these limits may compromise the pressure seal. In high-vibration areas, verify the connector torque periodically. The effects of 60 Hz magnetic fields up to 300 Gauss are minimal at typical gaps but should be considered in environments with large motors or transformers. Adhering to the temperature schedule for hazardous locations (EPL Ga, Gc, Dc) ensures safe operation in explosive atmospheres.
Selection Guide & Purchasing Advice
When ordering the 330172-00-08-10-02-05, confirm that your system requires a 5mm probe with 1.0 meter cable and ClickLoc connector. This model suits applications needing armored cable protection. For longer cable runs, consider alternative lengths (0.5, 2, 5, or 9 meters). Verify that your Proximitor sensor is compatible with 75 Ω triaxial cable.
