Industry Applications

The 330191-00-16-50-05 is ideal for monitoring shaft vibration and position in turbines, compressors, pumps, and other rotating equipment. Its robust design and precise measurement capabilities help prevent unplanned downtime and extend machinery life. In oil and gas, power generation, and manufacturing, this probe provides the data needed for predictive maintenance and condition monitoring.

Installation & Setup

Proper installation is critical for accurate readings. Ensure the probe is mounted with the correct gap and torque. The maximum connector torque is 0.565 N•m (5 in•lbf) to avoid damaging the connector. The probe case thread is 3/8-24 with a maximum engagement of 0.563 inches. Always follow the installation drawing and use the recommended Proximitor sensor. For 5-meter probes, only use the 5-meter Proximitor sensor to ensure compatibility.

Maintenance & Reliability

The 330191-00-16-50-05 is built for long-term reliability. The patented TipLoc molding method provides a robust bond between probe tip and body, while the CableLoc design offers 330 N (75 lbf) pull strength. The probe's PPS tip and stainless steel case resist harsh environments. Regular inspection of the cable and connectors is recommended to maintain signal integrity. The probe is designed to seal differential pressure between the tip and case, using a Viton® O-ring. Note that probes are not pressure tested before shipment.

Selection Guide & Purchasing Advice

When ordering, verify the total length (5.0 meters), thread type (3/8-24 UNF), and absence of armor. Confirm that your system uses the 5-meter Proximitor sensor. For applications requiring liquid sealing, consider the optional FluidLoc cable.
