Bently Nevada 21000-28-05-00-028-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-28-05-00-028-04-02 are listed below for quick reference:

Industry Applications and Cost Impact

The 2.8-inch probe penetration (Option D) allows precise gap adjustment for accurate vibration and position measurements. By enabling early detection of shaft vibration or thrust position changes, operators can schedule maintenance proactively, avoiding catastrophic failures that can cost hundreds of thousands in lost production and repairs. The CSA Type 4 explosion-proof rating ensures safe operation in hazardous areas, reducing the need for additional protective enclosures.

Installation and Setup Guidance

For probe penetration lengths between 1.0 and 2.0 inches, counter boring the machine case may be necessary to reduce side view or rear view effects. If the combined probe penetration (C plus D) exceeds 300 mm (12 in), sleeve support near the probe is required to prevent resonance. The adjustment range of Option D is 13 mm (± 0.5 in), allowing fine-tuning of the gap voltage. Use the 3/4-14 NPT mounting thread (Option F) for secure installation. Always follow the manufacturer's guidelines for conduit connections and hazardous area wiring.

Maintenance and Reliability

Inspect the housing assembly periodically for signs of corrosion or mechanical damage, especially in harsh environments. The aluminum body with 304 stainless steel sleeve provides corrosion resistance, extending service life. Verify that O-rings and thread seals are intact during routine maintenance to maintain the explosion-proof integrity. Regular calibration checks of the proximity probe system ensure measurement accuracy, minimizing false alarms and unplanned shutdowns.

Cost-Effective Vibration Monitoring with the Bently Nevada 21000-28-05-00-028-04-02
