This Bently Nevada 21000-16-10-00-144-03-02 includes one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and a cable seal grip with grommets for cable sizes from 1/8 to 3/8 inches.
Industry Applications
The 21000-16-10-00-144-03-02 excels in critical rotating equipment such as turbines, compressors, and pumps. Its rugged construction and CSA Type 4 enclosure rating make it suitable for hazardous areas classified as Class 1 Divisions 1 and 2, Groups C and D, and Class 2 Divisions 1 and 2, Groups E, F, and G. This housing provides a stable platform for proximity probes, ensuring accurate vibration and position measurements even in demanding environments.
Installation Guidance
Proper installation is essential for reliable performance. For probe penetration lengths between 1.0 and 2.0 inches, consider counter boring the machine case to reduce side or rear view effects. If the combined probe penetration (C plus D) exceeds 300 mm (12 in), add sleeve support near the probe to prevent resonance. The adjustment range for option D is 13 mm (±0.5 in), allowing fine-tuning of probe position.
Maintenance & Reliability
Regular inspection of the housing assembly ensures long service life. Check the O-rings and thread seals periodically to maintain the explosion-proof integrity. The aluminum body with 304 stainless steel sleeve resists corrosion, reducing maintenance frequency and downtime. This reliability translates directly to lower total cost of ownership.
Selection Guide
When ordering, verify the probe option, cable length, and penetration requirements match your machine specifications. PLC Source PRO offers this Bently Nevada 21000-16-10-00-144-03-02 as new and original in factory packing, backed by a 12-month warranty. Ensure you select the correct fittings and mounting thread for your installation.
