Industry Applications
The Bently Nevada 21000-16-05-00-084-04-02 excels in monitoring critical rotating equipment such as turbines, compressors, pumps, and motors. Its explosion-proof design makes it suitable for oil and gas facilities, chemical plants, and power generation stations where hazardous atmospheres exist. By providing accurate shaft vibration and position data, it helps prevent catastrophic failures and unplanned downtime.
Installation & Setup Guidance
When installing the 21000-16-05-00-084-04-02, ensure the mounting surface is clean and the 3/4-14 NPT thread is properly sealed to maintain the enclosure rating. Position the probe so that the 8.4 in penetration is correctly set, and the 0.5 m cable is routed without sharp bends. Verify the probe gap according to the system's calibration requirements before energizing the monitoring system.
Maintenance & Reliability
Regularly inspect the housing for signs of damage, corrosion, or loose fittings. Check the O-rings and thread seal periodically to maintain the explosion-proof integrity. Clean the exterior with a non-abrasive cloth to prevent buildup. With proper care, this assembly provides long-term reliability, reducing total cost of ownership.
Selection Guide & Purchasing Advice
Before ordering, verify the probe type, cable length, and mounting thread match your existing system. Confirm the 8.4 in probe penetration and fitting options align with your installation requirements.
