Industry Applications
This probe is ideal for monitoring shaft vibration and radial position in turbines, compressors, pumps, and motors. The 330173-00-02-20-02-05 delivers accurate gap measurements even in high-temperature environments, reducing unplanned downtime.
In a typical petrochemical plant, the probe's PPS tip resists chemical degradation, while the stainless steel case ensures long-term stability. Its 2-meter cable simplifies routing to junction boxes without signal loss.
Installation & Setup Guidance
Proper installation is critical for accurate readings. Follow these steps:
- Verify the thread size (M8 x 1) and ensure the mounting hole is clean and free of debris.
- Apply the recommended probe case torque of 5.1 N·m (45 in·lb) — do not exceed 7.3 N·m (65 in·lb) to avoid damage.
- Route the cable with a bend radius of at least 25.4 mm (1.0 in) to prevent stress on the internal conductors.
- Use the ClickLoc connector to secure the extension cable, tightening to a maximum of 0.565 N·m (0.42 ft·lbf).
For systems with high magnetic fields, refer to the provided 60 Hz magnetic field effect data to anticipate potential interference.
Maintenance & Reliability
Routine inspection of the probe and cable is recommended every 12 months. Check for physical damage, loose connections, and signs of wear on the PPS tip. The probe's stainless steel construction minimizes corrosion, but environmental factors such as excessive moisture or chemical exposure should be monitored.
If the probe is exposed to temperatures below -34°C (-30°F), the pressure seal may fail prematurely. Keep the probe within its specified temperature range to ensure a long service life.
Compatibility & Integration
This probe is designed for use with Bently Nevada 3300 XL 5mm systems. It works with 3300 XL Proximitor sensors and extension cables. The 75 Ω triaxial cable ensures signal integrity over distances up to 9 meters. For system integration, pair the 330173-00-02-20-02-05 with compatible Bently Nevada monitoring hardware.
Selection Guide & Purchasing Advice
Before purchasing, confirm the required probe length, connector type, and agency approvals. The 330173-00-02-20-02-05 is a specific configuration with a 2.0-meter cable and ClickLoc connector. If your system requires a different cable length or connector, consider other part numbers in the 3300 series.
