Industry Applications

The 330191-00-33-05-05 is ideal for vibration monitoring on turbines, compressors, pumps, and electric motors. Its robust 8 mm design withstands harsh industrial environments, reducing downtime and maintenance costs. The patented TipLoc molding and CableLoc design provide 330 N (75 lbf) pull strength, ensuring long-term reliability. Whether in petrochemical plants or power generation facilities, this probe delivers accurate data for predictive maintenance.

Installation & Setup Guidance

Proper installation is critical for optimal performance. 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 damage. For systems without extension cables (one-meter systems), verify the total length matches your requirements. Always follow the manufacturer's installation drawing and use compatible extension cables from Bently Nevada.

Maintenance & Reliability

Regular inspection of the probe and cable is recommended to detect wear or damage. The stainless steel case and PPS tip resist corrosion and physical abuse. The optional FluidLoc cable option prevents oil leakage, extending service life. For safety-rated applications, follow the manufacturer's safety manual for periodic testing and verification.

Compatibility & Integration

This probe works with Bently Nevada 3300 XL extension cables and monitors. It is designed for use with nonincendive circuits per installation drawing 140979. Multiple approvals ensure broad acceptance in various industries. Verify compatibility with your existing monitoring system before ordering.

Selection Guide & Purchasing Advice

When selecting a replacement probe, confirm the thread size (3/8-24 UNF), total length (0.5 m), and cable type.
