Bently Nevada 21000-34-05-00-050-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-34-05-00-050-04-02 are listed below for quick reference:

Application-Driven Design for Harsh Environments

This housing assembly is engineered for externally mounted proximity probes on critical rotating machinery. The aluminum body with a 304 stainless steel sleeve provides corrosion resistance and mechanical strength. With a 0.5 m probe cable and 5.0 in probe penetration, it suits installations where space is constrained or where the probe must reach through a housing wall. The 3/4-14 NPT mounting thread and single NPT plug fitting simplify conduit connections, reducing installation time.

Installation and Setup Guidance

When installing the 21000-34-05-00-050-04-02, ensure the mounting surface is clean and flat. Use the 3/4-14 NPT thread for a secure fit. The probe cable length of 0.5 m limits the distance to the monitor; plan cable routing accordingly. The housing includes O-rings and a thread seal for environmental protection. For hazardous area compliance, verify that the selected probe option matches the area classification.

Maintenance and Reliability

Periodically inspect the housing for signs of corrosion or damage, especially in harsh environments. Check the O-rings and seals during routine maintenance to maintain the CSA Type 4 enclosure rating. The 304 stainless steel sleeve resists wear, but verify probe tip clearance during shutdowns.

Selecting the Right Proximity Probe Housing for Critical Machinery Protection

When protecting rotating assets like turbines and compressors, the housing assembly is as vital as the probe itself. The Bently Nevada 21000-34-05-00-050-04-02 provides a robust, sealed enclosure for reliable vibration and position measurement in demanding environments. This guide helps you evaluate its specifications against your application needs.

Compatibility and Integration

This housing is designed for use with Bently Nevada 3300 XL 8 mm proximity probes and compatible monitors. The CSA approval ensures it meets hazardous area requirements. The assembly complies with API 670 for externally mounted housings, making it suitable for refinery and pipeline applications.

Purchasing Advice from AutoDCSTech

The 21000-34-05-00-050-04-02 is supplied as new and original in factory packing with a 12-month warranty. Please verify current lifecycle status and availability with AutoDCSTech before ordering. Our team can help confirm compatibility with your existing monitoring system.

Troubleshooting Common Issues

If you encounter signal instability, check the probe cable for damage and ensure the connector is properly seated. Verify that the housing is not loose on the machine. If the probe does not fit, confirm the probe penetration (5.0 in) and mounting thread (3/4-14 NPT) match your installation.
